Recipe: The Ultimate Gooey Peanut Butter Cup Dump Cake
- Prep time: 5 minutes
- Bake time: 40–45 minutes
- Servings: 10–12 people
Ingredients
- 1 box chocolate cake mix (approx. 430g)
- 1 package (100g) instant chocolate pudding mix
- 2 cups cold milk
- 1 bag (approx. 300g) mini Reese’s Peanut Butter Cups
- 1/2 cup peanut butter chips
- 1/2 cup unsalted butter, cut into thin slices
Instructions
- Prep the Base: Preheat your oven to 175°C (350°F). Lightly grease a 9×13-inch baking dish.
- The Candy Layer: Evenly scatter the mini peanut butter cups and peanut butter chips across the bottom of the dish.
- Dry Mix: Sprinkle the dry chocolate cake mix evenly over the candy layer. Do not stir.
- The Creamy Layer: In a bowl, whisk together the milk and instant pudding for about 2 minutes. Pour this mixture over the dry cake mix as evenly as possible.
- The Butter: Place the thin butter slices across the entire surface to ensure the dry mix is fully saturated during baking.
- The Bake: Bake for 40 to 45 minutes. The edges should be set, but the center should remain slightly “wobbly” or gooey.
- Serve: Let it rest for 10 minutes to set slightly before serving warm, preferably with vanilla ice cream.

Pro-Tips for Success
- To Prevent Dry Spots: Ensure the butter slices cover as much of the dry cake mix as possible. Any uncovered powder may remain dry after baking.
- The “Gooey” Factor: Using a prepared pudding layer instead of just plain liquid creates a fudge-like barrier that keeps the center molten.
- Customization: You can add dollops of chunky peanut butter over the candy layer for extra saltiness and texture.
Frequently Asked Questions (FAQ)
How do I make it extra gooey?
The secret to maximum “gooeyness” is the pudding layer. By pouring prepared instant pudding over the dry cake mix instead of just water or milk, you create a fudge-like barrier that prevents the cake from drying out. For an even more molten result, drizzle 1/2 cup of sweetened condensed milk or warmed peanut butter over the top halfway through baking.
Why is my dump cake dry?
A dry dump cake is almost always caused by uneven liquid distribution. If you see patches of dry flour on top after baking, it means the butter or pudding didn’t reach that spot. To fix this next time, ensure your butter slices cover as much surface area as possible, or use melted butter and pour it carefully in a zig-zag pattern over every inch of the dry mix.
Why is the center too gooey/liquid?
If your cake is “soupy” rather than “gooey,” it likely needs more time to set. Dump cakes continue to firm up as they cool. If it’s still liquid after 45 minutes, check your oven temperature. Also, remember that a dump cake is meant to be eaten with a spoon; it will never be firm enough to slice like a traditional sponge cake.
Can I use chunky peanut butter?
Yes! While the recipe calls for peanut butter cups and chips, you can absolutely dollop chunky peanut butter over the candy layer before adding the cake mix. This adds a fantastic saltiness and a crunch that cuts through the sweetness of the chocolate.
