I knew from the moment I saw this cake on Annie’s blog that I had to make it. I love the chocolate and peanut butter combination, and I would probably say that it’s my favorite kind of dessert. I decided to make this cake for our young adult group dinner. It was a big hit! I thought it looked so pretty with the Reeses Cups- this cake makes for a fun presentation.
This cake starts with a chocolate cake from Dorie Greenspan. This is a great chocolate cake recipe. It’s very moist and fluffy and would be good with any kind of frosting. I really cannot say enough about Ina Garten’s peanut butter frosting. It’s amazing! I doubled the recipe and had some left over after frosting the cake. I must admit, I’ve been dipping my fingers and eating it straight :) This is a great peanut butter frosting recipe and would be good with other cakes, cupcakes, and brownies. This is a fabulous cake and one I would definitely make again!
Reese’s Cup Chocolate Peanut Butter Cake
For the cake:
2 cups all-purpose flour
½ cup unsweetened cocoa powder
½ tsp. baking powder
½ tsp. baking soda
½ tsp. salt
2 sticks unsalted butter, at room temperature
1 ½ cups sugar
2 large eggs
2 large egg yolks
1 tsp. vanilla extract
1 cup buttermilk
4 oz. bittersweet chocolate, melted and cooled (optional)
1 ½ – 2 batches peanut butter frosting
miniature Reese’s cups, halved and/or chopped
For the cake, center a rack in the oven and preheat the oven to 350°. Butter two 9×2″ round cake pans, dust the insides with flour, tap out the excess and line the bottoms with rounds of parchment paper. Place the pans on a baking sheet.
In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda and salt. Set aside.
In a stand mixer fitted with the paddle attachment, beat the butter on medium speed until soft and creamy. Add the sugar and beat for about 2 minutes, until thoroughly blended into the butter. Add the eggs and yolks one at a time, beating for one minute after each addition and scraping down the sides of the bowl as needed. Beat in the vanilla. Reduce the mixer speed to low and add the dry ingredients alternately with the buttermilk; add the dry ingredients in 3 additions and the buttermilk in 2 (beginning and ending with the dry ingredients). Mix each addition only until it is blended into the batter. Scrape down the bowl and add the melted chocolate, if using, folding it in with a spatula. Divide the batter between the prepared cake pans.
Bake for 26-30 minutes or until the cakes feel springy to the touch and start to pull away from the sides of the pans. Transfer to wire racks to cool for about 5 minutes, then run a knife around the sides of the cakes, unmold them and peel off the paper liners. Invert and cool to room temperature right side up.
To assemble the cake, place one cake layer on a cardboard circle covered in foil. Spread peanut butter frosting on top of the cake layer. (If desired, sprinkle with chopped Reese’s cups.) Place the second cake layer on top of the frosting. Frost the top and outside of the cake with remaining peanut butter frosting. Decorate with halved and chopped Reese’s cups as desired.
