Cake:
1 box devil�s food cake mix
3 eggs
1 cup buttermilk
1/3 cup vegetable oil
2 cups peanut butter and milk chocolate swirled chips
Ganache:
1 1/2 cups semi sweet chocolate chips
1 cup heavy cream
4 tablespoons butter
1/2 cup peanut butter
1 cup powdered sugar
Recipe
Grease two round cake pans. Then in a bowl combine the cake mix, eggs, buttermilk and vegetable oil, mixing on high for two minutes. Stir in peanut butter/milk chocolate chips. Bake at 350 degrees for 30 minutes (check early) and cool on a wire rack.
In a small saucepan melt the butter, chocolate chips, cream and sugar. Stir constantly until smooth and melted. Stir in peanut butter and bring to a gentle boil. Cool. If needed, place in freezer, stirring every ten or fifteen minutes until it reaches spreadable consistency then frost cake in between the layers and over the outside, garnishing with extra peanut butter/milk chocolate chips.
My notes: I used a Betty Crocker triple fudge cake mix instead of the devils food; I used 1 cup or so of peanut butter chips and 1/2 cup or so of semi-sweet chips in the cake since my store didn't have the swirled chips; didn't bake the cake quite 30 minutes so check it early; I never did bring the ganache to a boil because I didn't want to scorch the chocolate; and after the ganache cooled, I beat it with a mixer before I spread it on the cake. I also topped the whole cake w/chopped up Reeses peanut butter cups so people would know it was a chocolate and peanut butter cake. I don't have any cake left, but I would have probably stored it in the fridge because I think the icing was getting a little soft after a while.
