Pretty Girl Makes Cupcakes

Hi everyone. Good news, I’m neither dead, nor retired from blogging. It’s just been a busy few months, and I haven’t had the time / energy to do much baking, and even less to do posting. Since my last post I’ve graduated from law school (hooray), started studying for the bar exam (boooo), and have started packing for a move to DC at the end of the summer. All in all, a busy time. Because of the bar don't expect many, or even any, new posts for awhile, but I thought I'd try for at least this one update.

This weekend though, I was fortunate enough to have a pretty girl help me make cupcakes (hence the title of the post). Hattie (the aforementioned pretty girl) and I made Chocolate-Banana-Peanut butter cupcakes for a Fourth of July party. These aren’t exactly new for me, as I’ve done a pretty fair number of chocolate peanut butter desserts, but I thought the addition of banana made these excellent. The cake is my basic chocolate, filled with a chocolate banana ganache, and frosted with a peanut butter frosting. The combination was excellent, if I can say so, and the banana really came through as a flavor in the ganache, even though you wouldn't suspect it (it just has the texture and appearance of regular whipped ganache).

Chocolate Cupcakes

Makes ~26

2 sticks unsalted butter

½ cup cocoa-powder

¾ cup water

2 cups sugar

2 eggs

½ cup well-shaken buttermilk

1 T vanilla

2 cups flour

1 tsp baking soda

1 t cinnamon

¼ tsp salt

1. Preheat oven to 350. Sift together the flour, baking soda, cinnamon and salt.

2. Melt the butter in a heavy bottomed sauce pan over low heat. Add in the cocoa powder and whisk until smooth. Then add the water and mix until smooth again. Remove from heat

3. One at a time mix in the sugar, egg, buttermilk, and vanilla

4. Sift the dry ingredients over the wet, and whisk until well combined.

5. Fill cupcakes using a ¼ cup measure. Bake for about 18-20 minutes, or until a tester comes out clean. Let them cool thoroughly before frosting.

Chocolate-banana ganache

8 oz. dark chocolate

½ cup heavy cream

½ cup banana puree

1. Chop the chocolate, and place it in a heat proof bowl.

2. Bring the cream to a simmer, pour over the chocolate, allow to sit for a minute, then stir until fully combined.

3. Stir in the banana puree. Allow to cool until set.

4. Pour cooled ganache into the bowl of a mixer, beat with whisk attachment until light in color and fluffy

Peanut Butter frosting

1 cup peanut butter

4 oz cream cheese, softened

1 ½ cups whipped cream (from about 1 cup cream)

1 cup powdered sugar

½ cup banana puree

1. Beat together the peanut butter, cream cheese, and powdered sugar until smooth.

2. Add the whipped cream and beat to combine. Beat in the banana puree.

Assembly

Use the cone method to fill the cupcakes with the whipped ganache. Top with the peanut butter frosting.

The Snickers

I’ve had the idea for this cupcake in my head since I first started baking a little over two years ago. I took a shot at it last year in the form of a cake, which was good, but not entirely what I was after. Largely because the nougat just didn’t work out. This weekend, however, I decided to take another shot, this time in a cupcake form. The result was a cupcake that I think definitely captured the essence of snickers, though at least some of my tasters thought that these were too much on the sweet side. I used a cocoa-based buttercream, mostly because I was lazy, I think a buttercream made with full chocolate might have been better. Either way, you might want to reduce the sugar from what I’ve listed. What I failed to keep in mind while tasting was that the nougat and caramel are both pretty sweet. For the cake I just used my favorite chocolate cupcake recipe, which held up well here with a nice chocolate flavor. The caramel recipe is from Martha Stewart’s Chocolate-Salted Caramel cupcakes

These are some of the most challenging cupcakes I’ve ever made, mostly because of the nougat. It’s taken me a good 5 or 6 tries to make it successfully, including two yesterday. For me I think the real problem is that nougat is just not common enough for lots of people to have written about, and so there aren’t a lot of instructions out there on how to make it. I followed the instructions here. I’ve done my best to write my full set of impressions below, but I think it is just one of those things to try a few times until you get the hang of it. The important thing is to coordinate everything in terms of timing, the egg whites and sugar need to be ready at the same time. Unfortunately, the recipe is in grams, which is what I did it in, but I got my grams scale for $5 at Kmart, and it’s worth having, so go out and get one.

The other challenge with these is the assembly. I cut my disks of nougat a little large (mostly because it was the smallest cutter I had). As a consequence I had to hollow out a lot of a large amount of cupcake. The thickness of the nougat also meant the holes had to be very deep. Especially since a layer of nuts and caramel also had to get in there. It’s definitely doable, but takes some effort. Also, the caramel needs to be spooned while it’s still hot, so I filled the cupcakes with the nougat and nuts first, then made the caramel.

Chocolate Cupcakes

Makes ~26

2 sticks unsalted butter

½ cup cocoa-powder

¾ cup water

2 cups sugar

2 eggs

½ cup well-shaken buttermilk

1 T vanilla

2 cups flour

1 tsp baking soda

¼ tsp salt

1. Preheat oven to 350. Sift together the flour, baking soda and salt.

2. Melt the butter in a heavy bottomed sauce pan over low heat. Add in the cocoa powder and whisk until smooth. Then add the water and mix until smooth again. Remove from heat

3. One at a time mix in the sugar, egg, buttermilk, and vanilla

4. Sift the dry ingredients over the wet, and whisk until well combined.

5. Fill cupcakes using a ¼ cup measure. Bake for about 18-20 minutes, or until a tester comes out clean. Let them cool thoroughly before filling.

Peanut Butter Nougat

Makes 1 9 x 13" pan

400 grams sugar

150 grams glucose (white corn syrup)

125 grams water pinch salt

60 grams egg whites (2 large eggs)

125 grams peanut butter

1. line the pan with parchment paper, and oil it. Place the peanut butter in a microwave safe bowl, put it in the microwave, set it for 1 minute, and set aside. Put the eggs and the salt in the bowl of a mixer set with the whisk attachment. Put the sugar, corn syrup, and water in a heavy bottomed saucepan, whisk until combined, and place over high heat.

2. Turn on the mixer to high speed, whisking the eggs up to stiff peaks. Ideally you want the eggs to reach stiff peaks at the same time the sugar gets to the right temperature, but it’s hard to coordinate, and it’s easier to stop egg whites from beating than caramel from cooking. If the eggs get to stiff peaks before the caramel ready, turn off the mixer.

3. While the egg whites are whipping, heat the sugar to 270F. When the sugar hits about 250, turn on the microwave to melt the peanut butter (it’s just a lot easier to mix in melted peanut butter than solid).

4. As soon as the caramel hits 270, turn the mixer on high, and slowly pour the caramel down the side of the bowl.

5. Continue beating the mixture until it cools off slightly, and becomes just slightly doughy. It should still be pretty hot. Remove from the mixer, and gently fold in the melted peanut butter. DO NOT OVERBEAT, or you will make it crumbly. It should still be pourable when you’re done. My first batch needed to be scooped out of the bowl, and didn’t spread at all, it was also immediately crumbly. The second, successful batch poured out of the bowl and flowed properly to fill the pan.

6. Set aside to let cool completely.

This is the successful nougat

This is what the failed nougat looked like

Assembly stage 1

Nougat

Chocolate Cupcakes

Lightly salted peanuts

1. Using a small, circular cutter, cut out disks of nougat. It should cut fairly easily.

2. Cut large, deep cones in the cupcakes. You may need to do some extra hollowing out with the tip of your knife.

3. Place a disk of nougat into each cupcake, top with a few peanuts.

4. Cut the bottoms off of the cones you removed, so that you only have the top, place it back on the cupcake it came from, just to keep track of the proper caps.

I don't know why blogger keeps rotating my images, anyone know how to fix it?

Salted Caramel

2 & 1/2 cups sugar

2/3 cup water

1 tablespoon light corn syrup

3/4 cup heavy cream

1 & 1/2 teaspoons sea salt

1. Place sugar, water, and corn syrup in a heavy bottomed saucepan, stir until clear. Stop stirring and bring to a boil. Continue heating until caramel reaches 360 degrees.

2. Remove from heat. Immediately stir in cream, be careful, the caramel will bubble up and steam. Add the salt and continue stirring.

Assembly Stage 2

Cupcakes from stage

1 Caramel

1. As soon as the caramel becomes manageable, remove the caps from the cupcakes, pour caramel in over the nuts, and reaffix the cupcake tops.

Chocolate Buttercream

3 sticks unsalted butter, softened

1 ½ cups cocoa powder

~4 cups powdered sugar

¼ cup milk

1. Beat the butter until smooth. Add the cocoa, the milk. Beat in the sugar 1 cup at a time, until the frosting reaches a flavor and consistency you like.

2. This frosting was too thick to pipe, so I just spread it on with a spoon. Top with a sprinkling of peanuts.

Chocolate Peanut Butter Mousse Cake

So, I’ve become negligent about posting again. Unfortunately it’s been busy lately. Fortunately though, this cake is an excellent return. It is, admittedly, pretty much the cake version of a cupcake I made over the summer. But that didn’t stop it from being excellent. I also used the “Deep Dark Chocolate Cake” recipe from bakewise as the cake, which was an excellent choice. Very chocolaty and moist. This recipe makes more peanut butter mousse than I needed, but I imagine you can find a creative use for the extra. Special thanks, as always, go to my friend Jessica, who helped me a great deal in making this cake (particularly by making the actual cake part).

Chocolate and Peanut Butter Mousse Cake

Chocolate Cake Layers

Makes 3, 8 inch layers

4 cups + 2 T sugar

1 tsp salt

1 cup + 2 T Dutch Process Cocoa Powder

1 ½ tsp baking soda

1 ½ cup water

1 ½ cup canola oil

3 tsp vanilla extract

2 ½ + 2 T Spooned and Leveled AP flour

6 large egg yolks

3 large eggs

3/8 cup buttermilk

1. Preheat oven to 350 degrees. Generously butter cake pans, line with parchment, and butter the parchment.

2. In a heavy saucepan stir together the sugar, salt, cocoa, and baking soda. Bring the water to a boil, stirring constantly, pour the water slowly into the cocoa mixture. Stir the mixture. Place on the heat and bring back to a boil. Turn off and allow to stand for 10 minutes.

3. Pour the cocoa mixture into a large mixing bowl, add the oil and vanilla and beat on low speed for 10 seconds. Still on low speed add the flour, and then quickly add the eggs, yolks, and buttermilk. Pour the batter into the prepared pans, filling about 2/3 full. If you have extra, make them into cupcakes (that’s what I did).

4. Bake for about 30 minutes, until the cake is set, pulls away from the sides of the pan, and a tester comes out clean. Let cool in the pans for 10 minutes, and then invert onto cooling racks to cool completely.

Peanut-Butter Mousse

2 cups creamy peanut butter (not natural)

2 8oz package cream cheese, room temperature

2 cup powdered sugar

2 T vanilla

2 cup chilled whipping cream

1. Beat the peanut butter, cream cheese, powdered sugar, and vanilla together until smooth and well blended.

2. Using clean, chilled beaters, and a chilled bowl, beat the cream to stiff peaks.

3. Fold ¼ of the whipped cream into the peanut butter mixture. Fold in the remaining whipped cream ¼ at a time. Fold until smooth and well mixed. Chill in the fridge until ready to use.

Peanut-butter Ganache

18 oz. dark chocolate, chopped

1 cup creamy peanut butter

2 cups heavy cream

1. Put the peanut butter and chocolate in a bowl.

2. Heat the heavy cream to a simmer, pour over the chocolate

3. Let the cream sit for a minute, then stir until thoroughly mixed. Let the ganache cool until it thickens enough to be spreadable.

Assembly

Place one layer flat side down. Spread about 2 cups of the peanut butter mousse on the cake, all the way to the edge. Place the most imperfect layer in the middle. Spread another 2 cups of peanut butter mousse on the cake. Place the final layer on top, flat side up. Pour about half the ganache over the cake, use an offset spatula to spread it all around the top and sides covering all of the cake. Once this layer of ganache, reheat the remainder just until it flows, and pour it over the cake. I found this ganache was too thick to just let it run down the cake, so I still had to use a spatula to spread it all around. I used a little extra peanut butter mousse to do the decorations.

Double Peanut Double Chocolate Cookies

A friend of mine was hosting a barbeque (cookout of you're a southerner who insists pulled meats must be present for it to be a barbeque). I decided to make up some cookies to bring. I got this recipe from epicurious, but instead of using chocolate chips and peanut butter chips, I used mini peanut butter cups from Trader Joes. These has a nice, cakey texture (if you like a cakey cookie), but I thought they were a little lacking in flavor.

Double Peanut Double Chocolate Cookies

Recipe says it makes 60, but I thought it made closer to 40

1 cup flour

1/2 cup unsweetened cocoa powder

1/2 tsp baking soda

1 tsp baking powder

1 1/2 sticks (3/4 cups) unsalted butter, softened

1/2 cup peanut butter (don't use natural)

3/4 cup white sugar

1/4 cup light brown sugar

2 large eggs

1 tsp vanilla

2 cups mini peanut butter cups

1. Preheat oven to 350. In a large bowl whisk together the flour, cocoa powder, baking soda, and baking powder.

2. In another bowl, cream the butter, sugars, and peanut butter together until light and fluffy. Beat in eggs one at a time, followed by vanilla.

3. Beat in flour mixture, and stir in mini peanut butter cups.

4. Drop dough by teaspoons two inches apart onto a parchment or silpat lined baking sheet. Bake for 10 minutes, remove from oven and cool on cookie sheets for ten minutes before removing to baking racks.

Decadent Chocolate-Peanut Butter Cupcakes

For the end of my summer job, one of my coworkers threw a party so that all of us could celebrate. I, inevitably, made cupcakes (this really has been a cupcake heavy summer, probably because my cupcake pans are all I brought with to DC). For this particular party I let my coworkers vote on cupcake choices. I made the first and third choices (the second was made by another coworker). The number one choice was chocolate-peanut butter cupcakes. For the cupcake base I used one of my standard chocolate-cupcakes, which I filled with a peanut-butter mousse, and frosted with a peanut-butter ganache. The cupcakes were really rich, but excellent. Key to their success was cutting out large cones from the centers of the cupcakes, so that lots of mousse could get in.

Mixed Nut and Chocolate Cookies

It turns out I have had some time to bake while here in DC for the summer, so I decided to make some cookies to bring into the office. My original intention was to make cashew butter cookies with white chocolate, but the store was out of cashew butter, so instead I used almond butter. But, it turns out I didn’t have enough almond butter, so I had to use some peanut butter. And of course, the ground nuts I used (I chopped them with a knife), were cashews. Hence why these are a mixed nut cookie. I also used both white and semisweet chocolate chips in these cookies. Overall, I’m not positive the variety of nuts or nut butters really came through, it might have been easier to just use peanut-butter, but the cookies themselves were excellent. The recipe is based on one I found here. I made these cookies small, and doubled the recipe when I made it, which made a huge number of cookies, nearly 150.

2 1/2 c flour 

1/2 tsp baking powder 

1/2 tsp baking soda 

1 tsp salt 

16 Tbs (2 sticks) unsalted butter, softened but still cool 

1 c brown sugar 

1 c granulated sugar 

1 c almond butter 

2 large eggs 

1 T vanilla 

1 c cashews 

6 oz. white chocolate chips 

6. oz. semi-sweet chocolate chips.

1. Preheat oven to 350 degrees. Whisk together the flour, baking soda, baking powder and salt.

2. Beat the butter until creamy. Add the sugars and beat until fluffy. Add the vanilla, followed by the eggs one at a time.

3. Beat in the almond butter. Stir in the flour mixture, followed by the chopped cashews and the chocolate chips.

4. Roll the cookie dough into 1 T sized balls. Place on cookie sheets 1-2 inches apart. Bake for 11 minutes, or until just browned. Remove from the oven and let cool.

A Dessert to Share

Sorry about the long delay, but it's a busy season in law school. It was my friend Joe's 30^th birthday the other day, and I volunteered to make the cake with the help of my friend Jessica. I was told Joe's favorite kinds of cake were cheesecake, and chocolate cake. Being an indecisive person, I decided that rather than choosing one, I would combine the two. The obvious choice was a brownie bottomed cheesecake. Some quick googling turned up this recipe for a brownie bottomed peanut butter cheesecake. This cheesecake was amazing, good enough that people cursed me out when they felt compelled to go back for more. Which is why this is a cheesecake to share, so that you won't end up eating the whole thing. This recipe does make more cheesecake batter than is needed, so I made a second smaller cheesecake with the extra. I tried to make a pretzel crust for it, but I didn't like it, so I didn't bother to include the recipe for it.

Peanut Butter Cup Brownie Bottom Cheesecake

Brownie Crust

6 Tbsp unsalted butter, melted
1-1/4 cups sugar
1 Tbsp vanilla extract (I used Madagascar Bourbon Vanilla)
2 eggs
1 cup plus 2 tablespoons all-purpose flour
1/3 cup unsweetened cocoa
1/2 tsp baking powder
1/2 tsp salt1 cup semi-sweet chocolate chips 

1 cup peanut butter chips

1. Heat oven to 350°F. Grease 9-inch springform pan with butter.

2. Stir together butter, sugar and vanilla in large bowl with spoon or wire whisk. Add eggs; stir until well blended. Stir in flour, cocoa, baking powder and salt; blend well. Spread in prepared pan.

3. Bake 25 to 30 minutes or until brownie begins to pull away from side of pan. Meanwhile make cheesecake layer (see below).

4. Immediately after removing brownie from oven, sprinkle milk chocolate chips, peanut butter chips and peanut butter cups over brownie surface. Spoon cheesecake mixture over chips. Turn down oven 325°.

Cheesecake Filling
2 lbs cream cheese, softened
5 eggs, at room temperature
1-1/2 cups firmly packed brown sugar
1 cup smooth peanut butter (not natural-style)
1/2 cups whipping cream
1 Tbsp vanilla extract
1 cup mini peanut butter cups*

*These were chocolate chip sized peanut butter cups I got from Trader Joes, if you can’t find them, skip them

1. Beat cream cheese in bowl of electric mixer until smooth.

2. Add eggs, one at a time, beating well after each addition. Add sugar, peanut butter and cream; mix until smooth.

3. Stir in vanilla and mini peanut butter cups.

4. Pour filling into prepared crust. (I poured the rest off into a smaller springform pan)

5. Double-wrap springform pan with aluminum foil to prevent water seeping in. Place springform pan into a larger baking pan. Pour hot water into the larger pan so that the water comes 1 inch up the sides of the springform pan. (This is easiest to do once you have already moved the pan into the oven, that way you don’t have to try to move a pan full of water).

6. Bake at 325 degrees 1-1/2 hours, or until firm and lightly browned.

7. Remove from the oven and allow to cool on a wire rack for one hour.

8. Run a knife along the edge of the cake to loosen it from the pan somewhat.

9. Refrigerate for at least 4 hours before decorating. I tend to make cheesecakes a day ahead to let things set.

Decoration

¼ cup whipping cream 

½ cup chocolate chips 

½ cup peanut butter chips

1. Place all ingredients into a microwave safe bowl. Microwave on medium power in 30 second bursts, whisking after each, until mixture is fully combined.

2. Let the ganache sit out until it has firmed up enough to pipe. Use to decorate the cake as you choose.

Stir Fry Noodles with Peanut Sauce

I’ve had some rice noodles in my pantry for a long time now. I bought them way back when I made pad thai last summer, and then set them in the back of the pantry and forgot about them until today. I wanted to make dinner without going shopping, so I decided to use them this week. I combined the method I learned to make pad thai with one of my favorite peanut sauces for stir fry, and I was very pleased with the results. I made this just for myself, so the recipe makes only one serving. Use whatever vegetables you like in stir fry, I used broccoli, grated carrots, green onion, bean sprouts, and water chestnuts. This recipe is easily made vegetarian by replacing the chicken broth with vegetable broth and omitting the chicken and fish sauce.

Stir Fry Peanut Noodles

For sauce:

1 T peanut butter
2 T Chicken Broth
1 T Low Sodium soy sauce
2 t honey
2 t mirin (rice wine)
2 t rice vinegar
1 t fish sauce
1 t thai chili paste (optional / to taste)

 

For Stir Fry

2 cloves garlic, finely diced 

2 tsp diced ginger 

½ cup rice stick noodles 

½ cup diced chicken 

½ cup vegetables to stir fry 

1 T sesame oil

1. Put the rice noodles in a pot of warm water. Let the noodles sit in the water for 15-20 minutes, until noodles are flexible, but still al dente

2. Put the oil in a wok or large pot over medium high heat. When the oil is hot enough that water boils on contact, add the ginger and garlic. Stir fry for 30 seconds.

3. Add the diced chicken and continue stir frying. Add a tablespoon of the sauce. Some of it will burn to the bottom of your pan, don’t worry about it.

4. When the chicken is cooked through, add the noodles, the vegetables, and the rest of the sauce. Stir fry the mix. Cook until the vegetables and noodles are cooked, 1-2 minutes. Immediately remove from heat and serve. 

Peanut Butter Swirl Brownies

I made these brownies to bring to a friend’s football party. The recipe comes from Martha Stewart’s Cookie Book. I’ve got to say, I’ve made a lot of recipes from this book now, and I think they’ve all turned out well. This book is definitely worth the investment if you’re interested in some pretty straightforward baking.

 I used my baker’s edge pan to make these, which is why the pan in the pictures looks a little odd. I did end up with brownies that were all edge pieces though.

Peanut Butter Swirl Brownies

Makes an 8x8 pan

For the Batter:

½ cup (1 stick) unsalted butter cut into small pieces 

2 oz. unsweetened chocolate, coarsely chopped 

4 oz. semisweet chocolate, coarsely chopped 

2/3 cup AP flour 

½ tsp baking powder 

¼ tsp coarse salt 

¾ cup sugar 

3 large eggs 

2 tsp vanilla extract

For the filling

4 tablespoons (1/2 stick) unsalted butter, melted 

½ cup confectioner’s sugar 

¾ cup smooth peanut butter 

¼ tsp salt 

½ tsp vanilla extract

1. Preheat oven to 325 degrees. Butter an 8x8 baking pan and line with parchment, allowing a 2-inch overhand. Butter the lining.

2. Melt the chocolate and butter in a heat proof bowl. Stir until smooth. In a separate bowl whisk together the flour, baking powder, and salt.

3. Whisk the sugar into the chocolate mixture. Add eggs and mix until smooth. Stir in the vanilla

. Add the flour mixture; stir well until combined.

4. Stir together all the ingredients for the filling in a separate bowl.

5. Pour 1/3 of the batter in the baking pan. Put tablespoons of the peanut butter filling on the batter, spread about an inch apart.

6.  Pour the remaining batter over the top, and smooth with a spatula.

7. To make the swirl pattern, place dollops of the remaining peanut butter mixture on top of the brownie batter. Drag a butter knife back and forth through the brownies and peanut butter to create a swirl pattern (see the pictures).
