- 1 package devil's food cake mix
- 1 (12 ounce) can cherry pie filling
- 3 eggs
- 1/3 cup vegetable oil
- 1 cup white sugar
- 5 tablespoons butter
- 1/3 cup milk
- 6 ounces chocolate chips
- Preheat oven to 350 degrees F (175 degrees C). Grease a 9×13-inch baking dish.
- Combine cake mix, cherry pie filling, eggs, and oil in a large bowl with an electric mixer on low speed until moistened, about 30 seconds. Beat at medium speed until a light and fluffy batter forms, about 2 minutes. Pour batter into prepared baking dish.
- Bake in preheated oven until a toothpick inserted into the center comes out clean, 26 to 30 minutes. Cool in the pans for 10 minutes before removing to cool completely on a wire rack.
- Heat sugar, butter, and milk together in a saucepan over medium heat. Simmer, stirring constantly, until smooth and thickened, about 5 minutes. Remove from heat, add chocolate chips, and stir until dissolved. Set aside to cool and thicken to icing consistency, about 20 minutes.
- Poke holes in top of cake. Pour chocolate icing over cake, allowing it to run down edges of cake.
