How to Make It
Creating this cake is simple and rewarding.
Prepare the Cake
Bake the chocolate cake in two 8-inch round cake pans according to the box instructions. Allow the cakes to cool completely before proceeding to the next step.
Make the Filling
Beat the softened cream cheese with an electric mixer until smooth. Add in the peanut butter and powdered sugar, continuing to mix until the filling is creamy and well-blended.
Assemble the Cake
Place one layer of the cake on a serving plate. Generously spread the peanut butter filling over the top. Carefully place the second cake layer on top.
Make Ganache
Heat the heavy cream in a saucepan until it begins to simmer. Pour the hot cream over the chopped dark chocolate, letting it sit for 5 minutes before stirring until smooth and glossy.
Top the Cake
Pour the ganache over the cake, allowing it to drip down the sides. Use a spatula to smooth it out as needed.
Garnish
Sprinkle crushed peanuts over the top of the cake. For extra flair, add chocolate bars or peanut butter cups as decorations if desired.
Chill and Serve
Chill the completed cake for at least 1 hour before slicing to make serving easier and to allow the flavors to meld beautifully.
How to Store It
Fridge: Store covered for up to 5 days.
Freezer: No, the ganache may not freeze well.
Reheat: Microwave in short bursts for about 10 seconds if desired.
Tips for Best Results
