Instructions

  1. Preheat the oven to 350°F. Spray 2 (8-inch round) cake pans with nonstick spray and set aside.
  2. In a large bowl, beat the cake mix, water, vegetable oil, peanut butter, and eggs together until just combined. Divide evenly between the two cake pans (about 534 grams per pan).
  3. Place into the oven to bake for 24 minutes, or until a toothpick inserted comes out clean. Once baked, remove from the oven and place onto a cooling rack to cool to room temp.
  4. While the cake is cooling, make the peanut butter frosting by combining the peanut butter, powdered sugar, butter, and vanilla in the bowl of a stand mixer fitted with a paddle attachment. Mix on low speed for 1 minute to allow the powdered sugar to be incorporated. Increase speed to high and beat for 3-4 minutes. Fill a piping bag fitted with a tip or a Ziplock bag with the corner cut off with ⅓ cup of the frosting. Set aside.
  5. To make the ganache, place the heavy cream into a microwave-safe bowl and heat for 60 seconds. Pour the heated heavy cream over the chocolate chips and let them set for a minute. Using a whisk or a fork, stir until the chocolate chips have completely melted and a smooth, chocolate ganache has formed. Set aside to cool.
  6. Once the cakes are cooled, place the first layer onto a cake stand or plate. Spread the remaining frosting onto the cake layer. Place the second cake layer on top, making sure the sides meet up and that there is no overhang on any of the sides. Pour the chocolate ganache onto the top of the cake. Using an offset spatula or spoon, spread the ganache to the edges of the cake and let it drip down the sides of the cake if you wish. Place the cake into the refrigerator for 15 minutes to allow the ganache to finish setting up.
  7. Once the ganache has set, remove the cake from the fridge and pipe peanut butter swirls onto the top of the cake around the edge in a circle formation. Slice and serve.

Notes

  • Storage: Store peanut butter layer cake in an airtight container at room temperature for up to 2 days or in the refrigerator for up to 4 days.
