Ingredients

Dr Pepper Chocolate Cake

1 box (13.25 oz) german chocolate cake mix
3 large eggs
1¼ cups Dr Pepper (not diet soda)
1/3 cup vegetable oil
1/2 cup mini chocolate chips

Chocolate Fudge Frosting

1/2 cup (1 stick) salted butter melted
1/3 cup whole milk
1/2 cup cocoa powder
2½ cups powdered sugar
1 teaspoon vanilla extract
1/3 cup chopped walnuts

Instructions

Preheat the oven to 350℉. Spray a 9x13 baking pan with nonstick cooking spray. Set aside.
In a large bowl, using an electric mixer, beat together the dry cake mix, eggs, Dr Pepper soda, and vegetable oil until combined well. About 1 minute. Start at low speed and increase speed as needed.
1 box (13.25 oz) german chocolate cake mix, 3 large eggs, 1¼ cups Dr Pepper, 1/3 cup vegetable oil
Stir in the mini chocolate chips. Pour the chocolate cake batter into the prepared pan and spread into an even layer.
1/2 cup mini chocolate chips
Bake for 26-35 minutes.
^{* The cake is done when a toothpick comes out clean, the cake bounces back when tapped, and the edges of the cake have slightly pulled away from the sides of the pan.}
Remove the cake from the oven and allow it to cool at room temperature while you prepare the frosting.
Make The Chocolate Fudge Frosting :
- Add the melted butter into a medium sized mixing bowl. Slowly whisk in the milk, while whisking constantly, until a creamy mixture forms. If the batter starts to clump, warm the bowl in the microwave for about 10 seconds.
- Add in the cocoa powder and whisk until it's smooth and combined (about 1-2 minutes). Again if the butter is clumping up, microwave the bowl for about 10 seconds to warm everything back up again.
- Add in the powdered sugar, 1/2 cup at a time, whisking continuously until smooth and completely incorporated. Whisk in the vanilla extract until smooth.
1/2 cup (1 stick) salted butter, 1/3 cup whole milk, 1/2 cup cocoa powder, 2½ cups powdered sugar, 1 teaspoon vanilla extract
Pour/spread the chocolate frosting over top of the warm cake. Immediately add the chopped pecans on top of the frosting.
1/3 cup chopped walnuts
Slice and serve the cake warm! The cake is really yummy served with a scoop of vanilla ice cream.

Notes

Cake Mix : I used the Betty Crocker Delights German Chocolate Cake Mix. It comes in the 13.25 oz box. The other brands are a 15.25 oz box - those will work just fine in the recipe if you can't find the Betty Crocker brand one. For some reason the Betty Crocker brand cake mixes are only 13.25 oz. Any chocolate cake mix variety can be used - chocolate, chocolate fudge, etc.
