The combination of chocolate fudge cake mix, instant pudding, and Dr Pepper creates a uniquely fluffy texture and a flavor that keeps everyone coming back for more.

I discovered this cake when I wanted an easy treat for a family gathering and was amazed at how something so simple could taste this indulgent. Now it’s a go-to for celebrations and casual weekend dessert alike.
Ingredients
- One box chocolate fudge cake mix: for a rich base and reliable texture, pick a quality brand with good cocoa
- One small box instant chocolate pudding mix around 3.9 ounces: adds moistness and extra chocolate flavor
- Three large eggs: essential for structure and richness, preferably fresh and room temperature
- One third cup oil: keeps the cake tender, use neutral oil like canola or vegetable
- One cup Dr Pepper soda: the star ingredient that introduces carbonation and subtle spice for lightness and depth
For the frosting
- Half a cup salted butter (one stick): richness and smoothness, use high quality butter for best flavor
- Three tablespoons unsweetened cocoa powder: natural deep chocolate taste, opt for Dutch processed if preferred
- Four to six tablespoons heavy cream or milk: adjust for desired frosting thickness, heavy cream makes it extra creamy
- Two cups powdered sugar also called confectioners sugar: sweetness and structure to the frosting
- One teaspoon vanilla extract: enhances overall flavor
- Half a cup chopped pecans or walnuts optional: adds a pleasant crunch and nutty contrast, choose fresh nuts
Step-by-Step Instructions
- Sauté the Oven and Pan:
- Preheat your oven to 350 degrees Fahrenheit. Lightly spray a 9 by 13 inch baking pan with nonstick spray so the cake won’t stick and you can serve it easily.
- Mix the Batter:
- In a large bowl, combine the chocolate fudge cake mix, instant pudding mix, eggs, oil, and Dr Pepper soda. Use an electric mixer on medium speed for about two minutes until everything is fully blended and smooth. This creates a light, airy batter ready to bake.
- Bake the Cake:
- Pour the batter into the prepared pan and place it in the oven. Bake according to the cake mix package directions, typically around 40 minutes. Expect a slight dip in the center, this is perfectly normal. Insert a toothpick to check doneness when it comes out clean, the cake is ready.
- Prepare the Frosting:
- While the cake bakes, melt the butter in a medium saucepan over medium low heat. Stir in the unsweetened cocoa powder and start with four tablespoons of heavy cream, stirring until smooth. Gradually whisk in the powdered sugar briskly to remove lumps. If the frosting is too thick, add more cream, one tablespoon at a time, to reach a spreading consistency. Remove from heat and stir in the vanilla extract.
- Frost and Garnish:
- Once the cake is cooled slightly but still warm, pour the frosting over it and spread evenly with a spatula. Sprinkle the chopped nuts evenly on top to add texture and extra flavor. Allow the frosting to set a bit as it cools.

Storage Tips
Store any leftover cake covered tightly with plastic wrap or in an airtight container at room temperature for up to three days. Refrigerate if your kitchen is warm, but bring the cake to room temperature before serving to enjoy the soft texture. This cake also freezes well, wrap tightly in foil and plastic and freeze up to three months. Thaw in the fridge overnight before serving.
Ingredient Substitutions
You can swap out Dr Pepper for another dark soda like root beer or cola for a slightly different flavor profile. Use light or regular vegetable oil if you don’t have any other options. For dairy-free frosting, substitute coconut cream for heavy cream and use a dairy-free butter alternative. If you prefer to avoid nuts, toasted coconut flakes or sprinkles can be a fun topping instead.
