Ingredients
Cake
- 2 cups sugar
- 1 3/4 cups all purpose flour
- 3/4 cup unsweetened cocoa powder
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- 1 teaspoon salt
- 2 large eggs
- 1 cup Dr. Pepper®
- 1/2 cup milk
- 1/2 cup vegetable oil
- 2 teaspoons vanilla extract
- 1 cup boiling water
Glaze
- 1/4 cup butter
- 1 tablespoon unsweetened cocoa powder
- 5 tablespoons Dr. Pepper®, divided
- 2 1/4 cups powdered sugar
Instructions
- Preheat and prepare pan: Gather all ingredients and preheat the oven to 350 degrees F (175 degrees C). Grease a 9x13-inch baking pan thoroughly to prevent sticking.
- Mix dry ingredients: In a large bowl, stir together sugar, all purpose flour, unsweetened cocoa powder, baking powder, baking soda, and salt until well combined.
- Add wet ingredients: Add eggs, Dr. Pepper, milk, vegetable oil, and vanilla extract to the dry mixture. Beat using an electric mixer on medium speed for 2 minutes to create a smooth batter.
- Incorporate boiling water: Carefully stir in the boiling water into the batter. The batter will be thin, which is expected for a moist cake.
- Bake the cake: Pour the batter into the prepared baking pan. Bake in the preheated oven for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean.
- Cool cake: Remove the cake from the oven and allow it to cool in the pan on a wire rack for at least 30 minutes. The cake should be cooled enough before glazing.
- Make the glaze: In a medium saucepan, combine butter, cocoa powder, and 3 tablespoons of Dr. Pepper. Cook and stir over medium-high heat until the mixture comes to a boil.
- Finish the glaze: Remove the saucepan from heat and whisk in powdered sugar until the glaze is smooth and creamy, about 2 minutes. Stir in the remaining 2 tablespoons of Dr. Pepper to achieve a smooth glaze consistency.
- Glaze the cake: Pour the prepared glaze evenly over the cooled cake, spreading if necessary to cover the entire top.
- Set and serve: Allow the glaze to set by letting the cake stand for 1 hour before serving to achieve the best texture and flavor.
Notes
- Ensure the boiling water is added carefully to avoid splashing and to maintain cake batter consistency.
- For an even moister cake, measure ingredients accurately and do not overbake.
- Store any leftover cake covered at room temperature for up to 3 days or refrigerate for longer freshness.
- Using full-fat milk and vegetable oil contributes to the cake’s moist texture.
- This cake pairs wonderfully with a scoop of vanilla ice cream for extra indulgence.
