Peanut butter and chocolate anyone?

So my new goal is to really only make and eat a treat one day a week. I'm going to go with Mondays for FHE......because family home evening is just better with treats. And since I'm only eating a treat once a week it's gonna be a good one. This cake was delicious!!! It was really easy since it uses a cake mix. Mine fell apart while I was trying to move it onto a different plate..... that's why it is in a bowl. If you want to see what it should look like you can check out bakerella.com.

1 box devil's food cake mix
3 eggs
1 c. buttermilk
1/2 c. oil
1-2 c. chopped peanut butter cups, plus more to put on top (I only put about a cup in the batter and it was still really good)
8 oz. chocolate (semi-sweet or dark), chopped (I used chocolate chips)
1 c. heavy cream
1/2 c. peanut butter

Beat cake mix, eggs, buttermilk, and oil on low for 30 seconds. Increase speed to medium and beat for 2 minutes. Fold in the peanut butter cups. Pour into two greased and floured (and waxed papered) round cake pans. Bake at 350 degrees for about 25 minutes or until done. Let sit in pans for 15 minutes and then remove to a wire rack to cool all the way. Heat the cream to just boiling and pour over the chocolate. Whisk until chocolate melts and then add the peanut butter. Stir until melted. Pour about 1 cup of frosting over the first layer of the cake. Top with other layer and pour rest of frosting on the top. Let it run down the sides of the cake and smooth the top and sides with a spatula. Top with more chopped peanut butter cups. Keep in the fridge.
