Looking for a delicious and easy dessert to satisfy your sweet tooth? Look no further than Dr Pepper Cake, made with a jazzed up cake mix and a delectable homemade frosting!
Preheat oven to 350F degrees. Spray a 9x13-inch baking pan with nonstick cooking spray.
In a large bowl, with an electric mixer, stir together 1 box chocolate fudge cake mix, 3.9 ounce small box instant chocolate pudding, 3 large eggs, ⅓ cup oil and 1 cup Dr Pepper soda for about 2 minutes on medium speed.
Pour batter into prepared baking dish and bake according to package directions. Note: The cake will have a slight dip in the center. This is normal. When it is done, a toothpick will come out clean. Once cake is done, then prepare the frosting.
For the frosting:
In a medium saucepan, over medium-low heat, start melting 1 stick (1/2 cup) salted butter.
Add in 3 Tablespoons unsweetened cocoa powder and 4-6 Tablespoons heavy cream and stir (note: start with 4 Tablespoons - you can always add more to reach your desired thickness after you add in the powdered sugar.)
Then whisk in 2 cups powdered sugar. Stir briskly with a whisk to get all the lumps out.
Take mixture off heat and stir in 1 teaspoon vanilla extract.
Pour frosting over cake and evenly spread it out.
Sprinkle ½ cup chopped pecans or walnuts evenly on top, if using. The frosting sets up more as it cools.
