I don't use cake mixes much. Not because I dislike them per se, it's just that I don't bake cakes that often and when I do, I usually want to make it from scratch! This particular recipes uses a cake mix as a base, and you add a bunch of other ingredients to it, then top it with peanut butter icing. I've made it I think 3 times over the past 5 years. It's really very good, the chocolate cake is dense (in a nice way!), very moist, and very chocolaty because of the added chocolate chips. I love the mini chips. They kind of melt into the cake, adding lots of extra flavor and gooey chocolate, and stay soft. The cake recipe is from AllRecipes, my only change is to replace half the oil with applesauce.
The peanut butter icing is from the Southern Plate blog, I changed it to use all butter instead of a mix of butter and shortening. The icing is perfect for this cake! It's thick, fudgy, sweet, and firms up rather than staying spreadable like regular frosting. The chocolate and peanut butter flavors work fantastically together and neither overpowers the other. This cake is a great choice for a peanut butter-chocolate lover!
Triple Chocolate Cake with Peanut Butter Fudge Icing
1 box devil's food cake mix (use the biggest you can find, mine was 16 oz)
6 oz box instant chocolate pudding mix
1/2 C water
1/2 C vegetable oil
1/2 C applesauce
1 C sour cream
12 oz bag mini chocolate chips
Preheat oven to 350 and grease a 9 by 13 baking dish.
Mix together everything except chocolate chips until smooth, then stir in chocolate chips. The batter will be thick. Spread it in the prepared baking dish and bake until a toothpick inserted into the center comes out mostly clean (the chocolate chips will prevent it from being completely clean), about 45 minutes.
Allow cake to cool completely before making icing.
