If you’ve ever dreamed of combining the rich, nutty flavor of peanut butter with the luscious sweetness of chocolate cake—all in one incredibly easy dessert—then the Peanut Butter Cup Dump Cake is about to become your new guilty pleasure. This is not your average cake recipe. It’s one of those “dump and bake” wonders that turns basic pantry ingredients into a gooey, decadent masterpiece with barely any effort. Whether you’re a seasoned baker or someone who just loves simple, comforting desserts, this treat is bound to make your kitchen smell like heaven.
What Is a Dump Cake?
For those who haven’t tried one before, a dump cake gets its name from the simplicity of its preparation. You literally “dump” your ingredients into a baking dish—no mixing bowls, no fancy equipment, and definitely no need for perfection. Traditionally, dump cakes use canned fruit, dry cake mix, and butter, resulting in a cobbler-like texture that’s gooey inside and slightly crisp on top.
But this Peanut Butter Cup version takes the concept to a whole new level. Instead of fruit, we’re using rich chocolate and peanut butter, turning this rustic recipe into something that tastes like a cross between a molten lava cake and a peanut butter cup brownie. It’s sweet, salty, and perfectly indulgent.
Ingredients You’ll Need
One of the best parts of this recipe is how simple the ingredients are. You probably already have most of them in your pantry:
- 2 cups of mini or chopped full-sized peanut butter cups
- ½ cup of creamy peanut butter, melted
- 1 box of chocolate cake mix (any brand works fine)
- 1 stick (½ cup) of unsalted butter, melted
- ½ cup of chocolate chips (optional, for extra gooeyness)
- Cooking spray or butter for greasing the pan
Optional toppings for serving:
- Vanilla ice cream or whipped cream
- A drizzle of warm chocolate or caramel sauce
- A sprinkle of crushed peanut butter cups for garnish
Step-by-Step Instructions
Step 1: Prepare Your Pan
Start by preheating your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or nonstick spray. This helps prevent the gooey bottom layer from sticking and makes cleanup a breeze.
Step 2: Layer the Peanut Butter Cups
Scatter your chopped peanut butter cups evenly across the bottom of the baking dish. These will melt and create a rich, fudgy base once baked, blending beautifully with the other layers.
Step 3: Add the Melted Peanut Butter
Drizzle the melted peanut butter over the candy layer. You don’t have to be precise—it’s a dump cake, after all! The idea is to create pockets of nutty flavor that will swirl through the chocolate during baking.
Step 4: Sprinkle the Cake Mix
Next, evenly sprinkle the dry chocolate cake mix over the peanut butter and candy layers. Don’t stir! Resist the temptation—keeping the layers separate is what gives dump cakes their signature texture: gooey in the middle and slightly crisp on top.
Step 5: Pour the Butter
Melt your stick of butter and pour it evenly over the top of the dry cake mix. The butter will soak through as it bakes, binding everything together into a decadent, melt-in-your-mouth dessert. You can also add a few splashes of milk or cream if you want a slightly moister texture.
Step 6: Add Chocolate Chips (Optional)
If you’re feeling extra indulgent (and who isn’t when chocolate and peanut butter are involved?), sprinkle chocolate chips over the top for more melty richness.
Step 7: Bake
Place the dish in the oven and bake for 35–40 minutes, or until the top is set and golden. The inside should still look gooey—that’s what makes it divine. If you prefer a firmer cake, add an extra 5 minutes of bake time.
Serving Suggestions
This dessert is best enjoyed warm, fresh from the oven, when the peanut butter cups are still melted and the chocolate is oozing. Here are a few delicious ways to serve it:
- With Vanilla Ice Cream: The contrast of cold and warm makes every bite magical.
- With Whipped Cream: A lighter topping that balances the richness.
- Drizzled with Chocolate or Caramel Sauce: For an extra layer of indulgence.
- As Leftovers: It reheats beautifully in the microwave for 15–20 seconds per serving.
