If you love the classic combination of chocolate and peanut butter, this Peanut Butter Cup Dump Cake is about to become your new favorite dessert. It’s rich, gooey, warm, and unbelievably simple — the kind of recipe you keep forever because it never disappoints. Dump cakes are known for being effortless, and this version takes that convenience to the next level by incorporating creamy peanut butter, chocolate cake mix, and melty Reese’s peanut butter cups. With no mixer needed, no complicated steps, and barely any mess, this dessert is perfect for busy nights, holiday gatherings, potlucks, or whenever you want a decadent sweet treat without spending hours in the kitchen.
What makes this dump cake truly special is its texture. As it bakes, the melted butter and milk transform the dry cake mix into a molten, pudding-like chocolate base. The melted peanut butter adds creaminess, while the candy pieces create tiny pockets of peanut butter richness. Every scoop delivers a layered experience: soft cake, gooey center, melty chocolate, and chewy peanut butter cups. It’s comfort food in dessert form — warm, indulgent, and guaranteed to be the first dish empty on the table.
Ingredients
•1 box (15.25 oz) chocolate cake mix
•1 cup milk (or amount required on the cake mix box)
•½ cup creamy peanut butter, melted
•½ cup butter, melted
•1 bag (10–12 oz) mini Reese’s Peanut Butter Cups
•1 cup chocolate chips (optional)
Instructions
1. Prepare Your Dish
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish or spray it with nonstick cooking spray. Dump cakes bake best in wide, shallow pans, so a glass or metal dish works perfectly.
2. Add the Dry Cake Mix
Pour the dry chocolate cake mix directly into the baking dish. Spread it out evenly using a spatula or spoon. Do not mix it with anything yet—this is the classic dump-cake method.
3. Mix the Wet Ingredients
In a separate bowl, whisk together the milk and melted peanut butter until smooth and combined. This mixture adds richness and helps hydrate the cake mix during baking. Pour it evenly across the dry cake mix.
Next, drizzle the melted butter over the top. The butter creates pockets of moistness and helps achieve that irresistible gooey center.
4. Add the Candy and Chocolate
Sprinkle the mini peanut butter cups over the entire dish, making sure they’re evenly distributed. As they melt, they’ll create creamy ribbons of peanut butter flavor throughout the cake. If you want a richer, more indulgent dessert, add chocolate chips as well.
5. Bake to Perfection
Place the baking dish in the oven and bake for 35–45 minutes. The top should look set, the edges should be bubbling, and the center should remain slightly soft — that’s the signature dump-cake texture.
Let the cake cool for about 10 minutes to thicken before serving.
Serving Suggestions
This dessert is phenomenal on its own, but even better paired with:
•Vanilla ice cream
•Whipped cream
•A drizzle of peanut butter or chocolate syrup
This Peanut Butter Cup Dump Cake is the perfect dessert for anyone who craves bold flavors with minimal effort. Its gooey texture, rich chocolate base, and pockets of melted peanut butter make it incredibly satisfying and dangerously addictive. Whether you’re preparing a last-minute treat, bringing dessert to a gathering, or simply indulging your sweet tooth, this dump cake guarantees compliments and empty plates. It’s fast, easy, and always a hit — the true definition of a crowd-pleasing dessert.
