Creating Cherry Dr Pepper Cake can be straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
2. Combine Dry Ingredients: In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking powder, and salt until evenly combined.
3. Mix Wet Ingredients: In another bowl, combine the Cherry Dr Pepper, vegetable oil, eggs, and vanilla extract. Whisk until well mixed.
4. Combine Mixtures: Gradually pour the wet ingredients into the dry ingredients. Stir until just combined, making sure not to overmix.
5. Add Cherry Pie Filling: If desired, gently fold in the cherry pie filling for added flavor and texture.
6. Divide the Batter: Evenly distribute the batter between the prepared cake pans.
7. Bake: Place the pans in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
8. Cool the Cakes: Once baked, remove from the oven and let them cool in the pans for about 20-30 minutes. After cooling, carefully transfer the cakes to wire racks to cool completely.
9. Frost the Cake: Once the cakes are completely cool, frost with your choice of frosting. Cream cheese frosting pairs exceptionally well with this cake.
10. Serve: Slice and serve the cake, enjoying the delightful combination of flavors.
