Easy Chocolate Peanut Butter Pudding Dump Cake Recipe
This chocolate peanut butter dump cake combines a soft chocolate pudding layer, creamy peanut butter, chocolate cake mix, and peanut butter chocolate chips in one baking dish. The top bakes into a buttery chocolate crust while the center remains warm and spoonable.
Unlike a traditional fruit-based dump cake, this version begins with prepared instant pudding. The cake mix is still added dry and should not be stirred into the pudding. Careful layering gives the dessert its distinct textures.
Serve the cake warm after a brief cooling period. Vanilla ice cream is a natural addition, although the pudding cake is rich enough to stand on its own.

Ingredients
- Nonstick cooking spray or softened butter, for the pan
- 1 package (5.9 ounces or 167 grams) instant chocolate pudding mix
- 3 cups (710 milliliters) cold whole milk
- 3/4 cup (190 grams) creamy peanut butter
- 1 cup (170 grams) semisweet chocolate chips, peanut butter chips, or a mixture
- 1 box (13.25 to 15.25 ounces or 376 to 432 grams) chocolate cake mix
- 1 cup (226 grams) salted butter, melted
- Vanilla ice cream or lightly sweetened whipped cream, for serving, optional
Instructions
Heat the oven to 350°F (175°C). Lightly grease the bottom and sides of a 9-by-13-inch baking dish.
Pour the cold milk into the prepared dish. Add the instant chocolate pudding mix and whisk for about two minutes, scraping the corners so no dry pudding remains. Let the mixture stand for five minutes. It should begin to thicken but does not need to become completely firm.
Place the peanut butter in a microwave-safe measuring cup or small bowl. Warm it for 20 to 30 seconds, just until loose enough to drizzle. Avoid overheating it.
Spoon or drizzle the peanut butter over the pudding. It does not need to cover the entire surface. Scatter the chocolate and peanut butter chips evenly over the peanut butter layer.
Sprinkle the dry chocolate cake mix over the dish. Break apart any large clumps and spread the mix from edge to edge. Do not stir it into the pudding.
Slowly drizzle the melted butter over the cake mix. Give special attention to the corners and any visibly dry areas. Some small patches of cake mix may remain exposed, but most of the surface should be moistened.
Bake for 40 to 50 minutes. The edges should be bubbling, and the top should look set with a few soft, fudgy areas. A toothpick is not a useful doneness test because the pudding underneath remains moist.
Set the dish on a heatproof surface and cool for at least 20 minutes. The pudding will thicken as the cake rests. Spoon into bowls and serve warm.
Why the Layers Should Remain Separate
The pudding supplies the moisture beneath the dry cake mix. During baking, steam rises from the pudding while butter soaks into the mix from above. Stirring everything together changes the texture and can leave the dessert heavy and pasty.
The peanut butter belongs between the pudding and cake mix. That position protects it from direct oven heat and distributes pockets of peanut butter through each serving. Warming it briefly makes it easier to spread without disturbing the pudding.
Butter coverage determines how evenly the topping bakes. Large dry sections can remain powdery, especially around the edges. Pour the butter in a thin stream and move methodically across the entire pan. If a patch still looks dry after several minutes in the oven, spoon a little melted butter over that spot and return the dish to the oven.
Choosing the Cake Mix, Pudding, and Peanut Butter

Devil’s food cake mix produces a deep chocolate flavor, while a standard chocolate or chocolate fudge mix makes a slightly milder chocolate cake mix dessert. Package sizes vary by brand. A box between 13.25 and 15.25 ounces works in a 9-by-13-inch pan without changing the other ingredients.
Use instant pudding rather than cook-and-serve pudding. Instant pudding thickens in cold milk before the cake enters the oven. Cook-and-serve mixes rely on stovetop heat and may not set predictably in this preparation.
Conventional creamy peanut butter is the most reliable choice. Natural peanut butter often separates into oil and solids, which can make the baked layer greasy in places and dry in others. If natural peanut butter is the only option, stir it thoroughly before measuring.
Whole milk produces a fuller pudding layer, but 2 percent milk also works. Plant-based milk may set more softly with some instant pudding brands because the formulas are generally developed for dairy milk. Check the pudding package before making that substitution.
Useful Variations
A few substitutions can change the flavor without altering the basic method.
Peanut Butter Cup Dump Cake
Replace the baking chips with about 1 1/2 cups of chopped miniature peanut butter cups. Scatter most of them beneath the cake mix, where they are less likely to scorch. Reserve a small handful and press them into the warm surface after baking.
Dark Chocolate Version
Use devil’s food cake mix, dark chocolate instant pudding, and bittersweet chocolate chips. A small pinch of flaky salt added after baking can offset the sweetness, particularly if unsalted butter was used.
More Peanut Butter Flavor
Use peanut butter chips for the full cup of baking chips. Increasing the creamy peanut butter itself beyond the listed amount can make the middle unusually dense, so chips are a better way to strengthen the flavor.
Crunchy Topping
Scatter 1/2 cup of chopped roasted peanuts over the cake during the final 10 minutes of baking. Adding them near the end reduces the chance that they will become too dark.
Serving and Storage
This easy chocolate peanut butter dessert is best served warm, once the pudding has had enough time to settle. Serving it immediately from the oven can produce a thin, molten center. After 20 to 30 minutes, it becomes thick enough to spoon while retaining a soft pudding texture.
Refrigerate leftovers within two hours of baking. Cover the dish or transfer portions to airtight containers and keep them refrigerated for up to four days.
Individual servings can be reheated in the microwave in short intervals until warm. The topping softens during storage and will not regain its original crust in the microwave. For a firmer top, place a portion in a small oven-safe dish and warm it at 300°F (150°C) until heated through.
Preventing Common Texture Problems
A powdery top usually means the butter did not reach part of the dry mix. Spread the cake mix in an even layer before adding the butter, then pour slowly rather than emptying the butter in several large pools.
If the center looks loose when the baking time ends, check the edges and top before extending the bake. Bubbling edges and a set surface usually indicate that the cake is ready. The pudding will remain soft while hot and continue thickening during the cooling period. Baking until the center appears completely firm can dry out the topping.
A thin pudding layer may result from using the smaller serving-size pudding package with three cups of milk. For this chocolate peanut butter dump cake recipe, use the 5.9-ounce family-size package and follow the recipe measurement rather than the directions for a different package size.
The dessert should be scooped rather than cut into clean squares. Its soft center is characteristic of a one-pan pudding cake, not a sign that the cake mix was left raw.
