Chocolate and Peanut Butter Mousse Cake
Chocolate Cake Layers
Makes 3, 8 inch layers4 cups + 2 T sugar
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 Mousse2 cups creamy peanut butter (not natural)
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 Ganache18 oz. dark chocolate, chopped
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.
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.
