Chocolate Cake with Chocolate Peanut Butter Frosting

If you put a bag of Reese’s in front of me, consider it gone almost immediately. It’s one of my vices, and I know I can’t keep that kind of stuff in my house. When my husband and I went shopping at Sam’s Club a few weeks ago, however, I saw Reese’s minis…in bulk. Ugh. I totally bought it, justifying that I would bake with them. Haha. Yeah…

Well, 1 bag mysteriously disappeared :-P, but then I was asked to bake up a simple cake for my work’s birthday club. Every month, they have a cake to celebrate birthdays for those in the office who had a birthday that month. Previously, they would just buy a sheet cake from a grocery store, but since my coworkers know I love to bake, they asked me to do it from now on. Um…how could I say no to that?!

I figured a Reese’s cake would be a tasty one, so I made chocolate cake with a chocolate peanut butter frosting, and then topped it with chopped Reese’s minis. The cake may not be the prettiest (ugh…my cake totally stuck to the pan in the corners so I used frosting to glue it back together), but darnit…it was GOOD! I had to pour dish soap on the leftover frosting or I seriously would have eaten the rest with a spoon. So good!

Ingredients:

For the cake:

  • 1 3/4 cups all-purpose flour
  • 2 cups sugar
  • 3/4 cups cocoa powder
  • 2 tsp. baking soda
  • 1 tsp. baking powder
  • 1 tsp. kosher salt
  • 1 cup buttermilk, shaken
  • 1/2 cup vegetable oil
  • 2 large eggs, at room temperature
  • 1 tsp. vanilla extract
  • 1 cup freshly brewed hot coffee

For the frosting:

  • 2 sticks unsalted butter, softened
  • 3 1/2 cups confectioners sugar, sifted
  • 1/2 cup cocoa powder, sifted
  • 1/2 tsp. salt
  • 2 tsp. vanilla extract
  • 1/4 cup peanut butter
  • 5 tbsp. heavy cream
  • optional: Reese’s minis (chopped), for decoration

Directions:

  1. Preheat the oven to 350 degrees. Prepare an 9×13 inch cake pan by lining the inside with baking spray or butter/flour
  2. Sift the flour, sugar, cocoa powder, baking soda, baking powder and salt into the bowl of an electric mixer, and mix on low speed with the paddle attachment until combined. In another large bowl, mix the buttermilk, oil, eggs and vanilla together. Turn the mixer on low speed again, and slowly add the wet ingredients to the dry. Scrape down the bowl with a spatula, and then slowly add the coffee and mix until everything is just combined.
  3. Pour the cake batter into the prepared 9×13 inch pan, and bake for 30-40 minutes, until a toothpick or cake tester comes out clean. Cool the cake in the pan for 30 minutes, and then turn it out onto a cooling rack to finish cooling.
  4. While the cake is cooling, make the frosting. Place the two sticks of butter in a clean bowl of your electric mixer, fitted with the paddle attachment and cream it on medium-high for 2 minutes, until light and fluffy. Turn the mixer to low and add the confectioners sugar, cocoa powder and salt until well-mixed. Scrape the bowl down, and then, add the vanilla extract, peanut butter and heavy cream and mix on low for 30 seconds to incorporate the ingredients. Turn the speed up to medium and whip up the frosting for 2-3 minutes, until fluffy.
  5. Once the cake is completely cool, frost your cake and if preferred, add the chopped Reese’s on top for decoration.
