Ingredients for Dr Pepper Chocolate Cake

This easy cake recipe starts with the essentials: a boxed chocolate cake mix, fizzy Dr Pepper soda, and a few flavor-enhancing add-ins. What makes this more than just a shortcut is the frost—a glossy, stovetop fudge drizzle that soaks right into the warm cake.

For the Cake

• 1 box (13.25–15.25 oz) chocolate cake mix (German chocolate or classic chocolate both work great)
• 3 large eggs
• 1¼ cups Dr Pepper soda (not diet soda — the sugar and fizz matter)
• ⅓ cup vegetable oil
• ½ cup mini chocolate chips (optional, but gives the cake batter that extra boost)

For the Frost (Fudge Icing)

• ½ cup (1 stick) salted butter
• ⅓ cup whole milk
• ½ cup cocoa powder
• 2½ cups powdered sugar
• 1 tsp vanilla extract
• ⅓ cup chopped pecans (or walnuts if preferred)

What You’ll Need

• Large mixing bowl
• Saucepan (medium-sized)
• 9×13-inch baking pan

This isn’t just any pepper cake recipe — it’s soft, rich, and totally elevated by the thick, chocolatey frost.

How to Make Dr Pepper Cake with Cake Mix

Step-by-Step Instructions to Make the Cake Moist and Fluffy

• Preheat your oven to 350°F. Lightly grease a 9×13-inch baking pan or line it with parchment paper.
• In a large bowl, combine the dry chocolate cake mix, eggs, Dr Pepper soda, and oil. Use an electric mixer to beat everything together until smooth—about 1 minute, scraping down the sides as needed. The cake batter should be silky and slightly airy from the soda.

• Gently stir in the mini chocolate chips. Pour the batter into the prepared pan, smoothing it out with a spatula.
• Bake for 26–32 minutes, or until a toothpick inserted into the center of the cake comes out clean. The edges will slightly pull away and the center should spring back when lightly touched.

• Once baked, remove the cake from the oven and let it rest at room temperature for 10–15 minutes. This allows the surface to set just enough before you make the frosting.

Tips to Frost and Set This Easy Cake Recipe

• In a medium saucepan, melt the butter over medium heat. Don’t let it brown—just melt it fully.
• Remove from heat, and immediately whisk in the milk, followed by the cocoa powder. Whisk until completely smooth and glossy.

• Gradually add in the powdered sugar, ½ cup at a time. Whisk or stir well between additions to avoid clumps. Mix in the vanilla.
• If the mixture thickens too fast, reheat it gently over medium heat until pourable. Once ready, pour the frosting over the still-warm cake.
• Quickly sprinkle the chopped pecans over the top before the frost sets. The warmth helps everything fuse into a gooey, glossy topping.

The key is timing—make the frosting while the cake is still warm, and you’ll get that signature fudge layer that soaks into the sponge perfectly.

Tips for a Moist and Fluffy Dr Pepper Cake

Here’s the truth: even the easiest cake mix can fail you if you rush it. We’ve all had a dry chocolate cake that looked gorgeous but felt like chewing a sponge. The fix? It starts with balance — and ends with timing.

The Secret Sauce (Literally): Fudge Frosting

The frost is not just topping — it’s the heart of this dr pepper cake. When you pour warm fudge over an equally warm cake, something magical happens: it seeps in, marrying that rich chocolate flavor with a sticky, glossy sheen that’s peak comfort food.

• Don’t skimp on the butter and cocoa powder — that’s where your classic chocolate depth comes from.
• Always whisk your powdered sugar in gradually to avoid clumps and keep the frosting smooth.

Baking Tips for a Truly Moist Cake

• Use Dr Pepper soda, not diet soda. The sugar and carbonation are essential. Dr Pepper adds moisture and that distinct pepper chocolate note.
• Keep an eye on your cake batter—overmixing kills the fluff.
• A pinch of baking soda (if you tweak the recipe from scratch) gives it extra lift.
• Don’t wait too long to pour the frosting—a slightly warm cake is key to proper absorption.

Want a moist cake every single time? Remember: timing, temperature, and trusting the process matter more than perfection.

Creative Dr Pepper Cake Variations

You’ve got the base cake down, but what if you want to play with flavor or ingredients? This is where the dr pepper cake becomes a choose-your-own-adventure sheet cake. Whether you’re trying to make this cake pop for a birthday or adapt to what’s in your pantry, here are a few flavor-forward twists.

Cherry Dr Pepper Cake: The Sweetheart Remix

If you love cherry notes in your pepper flavor, lean into it:

• Add halved maraschino cherries to the cake batter just before baking.
• Drizzle cherry syrup over the cooled cake for extra stickiness.
• Swap vanilla in the frost for almond extract for a nutty backdrop.

From-Scratch Option (If You’re Feeling Ambitious)

Want to try a dr pepper cake recipe from scratch? Skip the cake mix and combine:

• 2 cups flour, 1¾ cups sugar
• ¼ cup cocoa powder, 1 tsp baking soda, ½ tsp salt
• 3 eggs, 1¼ cups Dr Pepper soda, ½ cup oil
• Then continue with the same bake and fudge frost process.

Two-Ingredient Hack (No Judgment Zone)

Yep, the viral 2 ingredient Dr Pepper cake is real. Just mix:

• 1 box chocolate cake mix
• 1 cup of Dr Pepper

That’s it. Bake, cool, and top with store-bought frosting if you’re in a pinch for time.

The easy cake magic here is flexibility — you can go full DIY or keep it lazy and still end up with a wildly good pepper cake recipe.

How to Store or Freeze Dr Pepper Cake

One of the best things about this dr pepper cake? It keeps like a champ. Whether you’re prepping ahead for a party or just didn’t manage to finish it in one sitting (rare, but hey), here’s how to stash your cake the right way.

Short-Term Storage

• Keep your cake in an airtight container at room temperature for up to 3 days.
• If your kitchen runs warm, refrigerate it — just bring it back to room temperature before serving so the frost softens.

Freezing Tips

Want to freeze this cake for a later craving?

• First, make sure the frost has fully set and the warm cake has cooled completely.
• Wrap the whole baking pan tightly with plastic wrap, then cover again in foil.
• For easier grab-and-go, cut into individual slices and wrap each one in plastic wrap before placing in a zip-top freezer bag or airtight container.

Thaw slices at room temperature or warm briefly in the microwave if impatience wins.

Pro tip: While the texture of the fudge frosting may shift slightly after freezing, the cake itself stays soft and indulgent — like day one.
