Ingredients You’ll Need
Getting ready to bake this cake couldn’t be easier because the ingredient list is straightforward yet thoughtfully chosen to deliver incredible flavor and texture. Each component plays its part—whether it’s adding moisture, depth, or that luscious glossy frosting.
- 1 16 oz Devil’s Food box cake mix: The base for our rich and chocolaty cake, a foolproof shortcut that still bakes up beautifully.
- 1 cup Dr Pepper: Replaces the water in the mix, infusing the cake with those signature spiced soda flavors.
- ½ cup Dr Pepper: Used again in the frosting for a concentrated, reduced glaze of irresistible taste.
- ½ cup unsweetened cocoa powder: Adds deeper chocolate complexity to the frosting’s richness.
- ½ cup (1 stick) unsalted butter: Brings creaminess to the frosting and balances the sweetness perfectly.
- 1 teaspoon vanilla extract: Enhances aromas and layers in warmth to the frosting’s flavor.
- 4 cups sifted powdered sugar: The essential sweetness that transforms the reduced soda and cocoa into a smooth, spreadable frosting.
- Optional ½ cup chopped walnuts or pecans: Adds a delightful crunch and nutty contrast to the luscious frosting, if you’re feeling adventurous.
How to Make Dr. Pepper Cake Recipe
Step 1: Prepare and Bake the Cake
Start by mixing the devil’s food cake according to the box instructions, but here’s the twist—replace the water called for in the recipe with a full cup of Dr. Pepper. This substitution is what sets the mood for our cake, adding moistness and a subtle spice that you won’t forget. Pour the batter into a greased 9×13 pan and bake it exactly as directed on the box. Once baked, allow your masterpiece to cool completely before moving on to the frosting stage.
Step 2: Reduce Dr. Pepper for the Frosting
While your cake cools, pour the remaining ½ cup of Dr. Pepper into a small saucepan and bring it to a simmer over medium-high heat. You’ll want to reduce this liquid for about 15 minutes—watching closely as it thickens and intensifies in flavor—because this reduction is the secret behind your frosting’s unique character.
Step 3: Make the Chocolate Frosting
Add the unsweetened cocoa powder directly into the reduced Dr. Pepper and stir until fully dissolved. Next, soften in the butter by stirring it through until the mixture is silky and homogenous. Remove it from the heat and let it cool for about 10 minutes to avoid melting the powdered sugar in the next step.
Step 4: Finish the Frosting
Now for the sweet magic—gradually mix the sifted powdered sugar into your cooled chocolate-Dr. Pepper blend. Do this in increments to achieve a smooth, spreadable consistency. If you want to add a little textural surprise, fold in the optional chopped walnuts or pecans.
Step 5: Frost the Cake
Pour the warm frosting generously over the cooled cake, allowing it to spread out evenly. This decadent glaze will set into a beautiful shell as it cools, offering a perfect balance of gooey and firm textures. Let it rest until the frosting firms up, and your Dr. Pepper Cake is ready to dazzle the crowd.
How to Serve Dr. Pepper Cake Recipe
Garnishes
A simple dollop of freshly whipped cream or a scoop of creamy vanilla ice cream on the side elevates this cake to dessert perfection. These mild accompaniments complement the rich chocolate and subtle caramel notes without overpowering them. For an extra festive touch, sprinkle a few chopped nuts or drizzle a bit of chocolate syrup right before serving.
Side Dishes
This cake pairs beautifully with a cup of hot coffee or a chilled glass of milk—both balance the sweetness and help cleanse the palate. If you’re looking for a more elaborate pairing, consider fresh berries on the side or a citrus salad to cut through the richness of the cake.
Creative Ways to Present
For special occasions, try cutting the cake into small squares and serving them on decorative plates with a mint leaf on top for color contrast. You could also layer the cake with whipped cream and fresh fruit in parfait glasses for an elegant twist that showcases the beloved Dr. Pepper Cake Recipe in a new light.
Make Ahead and Storage
Storing Leftovers
Once frosted, keep your Dr. Pepper Cake covered at room temperature if you plan to eat it within a day. For longer storage, wrapping it tightly with plastic wrap or storing it in an airtight container in the refrigerator will keep it moist and flavorful for up to 3 days.
Freezing
This cake freezes wonderfully, which makes it great for prepping in advance. Wrap individual slices or the entire cake in plastic wrap and aluminum foil, then place them in a freezer-safe container or bag. Frozen, it will maintain quality for up to 2 months. When ready to enjoy, thaw in the refrigerator overnight.
Reheating
Warm slices gently in the microwave for about 15 to 20 seconds if you prefer the cake a bit softer and the frosting slightly gooey again. Avoid overheating as the frosting shell can melt too much and become overly sticky.
FAQs
Can I use regular soda instead of Dr. Pepper in this recipe?
While Dr. Pepper’s unique blend of flavors is key to this cake’s character, you could experiment with other sodas, but the taste will be different. Cola might work, but the spicy notes of Dr. Pepper are hard to replicate exactly.
Is it necessary to substitute Dr. Pepper for all the water in the cake mix?
Yes, substituting all the water with Dr. Pepper lets the cake fully absorb those flavors and moisture. Using less might reduce the cake’s distinct taste and texture.
Can I make this cake gluten-free?
If you find a gluten-free devil’s food cake mix that works similarly, you can try this recipe. Just ensure the other ingredients like vanilla extract and soda are gluten-free as well.
What texture should the frosting have once it cools?
After cooling, the frosting firms up forming a lightly crisp, shell-like coating while remaining soft inside. This contrast is one of the best parts of the Dr. Pepper Cake Recipe experience.
Can I add nuts to the cake batter itself?
Absolutely! Adding walnuts or pecans to the batter can give the cake an enjoyable crunchy surprise throughout. Just fold them in gently before baking.

Ingredients
Cake
- 1 16 oz devil’s food box cake mix (plus ingredients listed on box to prepare cake mix minus water)
- 1 cup Dr Pepper (to replace water called for in cake mix)
Frosting
- ½ cup Dr Pepper
- ½ cup unsweetened cocoa powder
- ½ cup (1 stick) unsalted butter
- 1 teaspoon vanilla extract
- 4 cups sifted powdered sugar
- Optional: ½ cup chopped walnuts or pecans
Instructions
- Prepare Cake Batter: Follow the package instructions for the devil’s food cake mix intended for a 9×13 inch pan, substituting 1 cup of Dr Pepper for the water. Mix all ingredients thoroughly to achieve a smooth batter.
- Bake the Cake: Pour the batter into the prepared 9×13 inch pan and bake according to the time and temperature specified on the cake mix box. Once done, remove from the oven and allow the cake to cool completely in the pan on a cooling rack.
- Reduce Dr Pepper for Frosting: In a medium saucepan over medium-high heat, simmer ½ cup Dr Pepper for about 15 minutes until it reduces and thickens slightly, intensifying the flavor.
- Add Cocoa Powder: Stir in the ½ cup unsweetened cocoa powder into the reduced Dr Pepper until fully dissolved to create a rich chocolate base for the frosting.
- Melt Butter: Add the ½ cup (1 stick) unsalted butter to the cocoa mixture and stir continuously until melted and combined. Remove the pan from heat and allow the mixture to cool for about 10 minutes.
- Combine with Sugar and Vanilla: Gradually stir in the 4 cups sifted powdered sugar into the cooled butter mixture, blending well after each addition until the frosting is smooth and glossy. Mix in 1 teaspoon vanilla extract. If desired, fold in the optional ½ cup chopped walnuts or pecans for texture.
- Frost the Cake: Pour the warm frosting evenly over the cooled cake surface. The heat will cause the frosting to spread and then firm up, creating a shiny shell coating.
- Serve: Once the frosting has set, cut the cake into squares. Serve each slice with a dollop of whipped cream or a scoop of vanilla ice cream for extra indulgence and enjoy!
Notes
- Substituting Dr Pepper for water in the cake batter adds a unique caramel and fruity flavor to the cake.
- Ensure the cake is fully cooled before frosting to prevent the frosting from melting excessively.
- The frosting will harden to form a shell; if you prefer a softer frosting, serve the cake shortly after applying the icing.
- Chopped walnuts or pecans are optional but add great texture and flavor.
- This cake pairs wonderfully with whipped cream or vanilla ice cream for a delicious dessert experience.
