Ingredients
Here’s what you’ll need to make this peanut butter dream come to life:
Peanut Butter Cups: These little bites of chocolate and peanut butter are the stars of the show. Their creamy, melty goodness takes this cake to a whole new level. If you’re feeling extra indulgent, feel free to chop up a few more and throw them on top for extra richness.
Cake Mix: The secret to a quick and easy dump cake is a box of cake mix. It creates the perfect, fluffy base while keeping everything super simple. No need to make the batter from scratch when the box mix does the job just fine.
Butter: Butter is the magic ingredient that makes this cake ooey, gooey, and wonderfully rich. It melts right into the cake mix, making everything come together perfectly.
Peanut Butter: For that extra peanut buttery goodness. It adds a creamy, rich flavor that pairs perfectly with the peanut butter cups and chocolate.
Milk: A splash of milk is the key to helping the cake bake up just right—giving it that moist, melt-in-your-mouth texture.

Instructions
Let’s dive in and get this cake ready to impress:
Preheat Your Oven: Start by preheating your oven to 350°F (175°C). This ensures your cake will bake evenly and reach the perfect golden-brown crust.
Prepare Your Baking Dish: Grab a 9×13-inch baking dish and lightly grease it. You want the cake to come out easily, and a little greasing goes a long way in preventing sticking.
Layer the Peanut Butter Cups: Take your peanut butter cups and layer them evenly across the bottom of the dish. You want them to be spread out well so every bite gets a bit of that melty chocolate-peanut butter goodness.
Add the Cake Mix: Sprinkle the dry cake mix evenly over the peanut butter cups. Don’t worry about mixing or spreading it out too much—this is a dump cake, so the more rustic the better.
Add Peanut Butter and Milk: Pour the peanut butter and milk over the cake mix. The milk helps everything come together, while the peanut butter gives it that extra richness. No need to stir anything—just let it all sit on top.
Top with Butter: Slice the butter into small pieces and scatter it across the top of the cake. This will melt and create a golden, crisp topping as it bakes.
Bake: Pop the dish in the oven and bake for 30-40 minutes. You’ll know it’s ready when the top is golden and the cake is bubbling around the edges. The aroma will be absolutely irresistible!
Serve and Enjoy: Let the cake cool for just a few minutes, then serve it up warm. I recommend a scoop of vanilla ice cream on top—because, why not? The combination of the warm cake and cold ice cream is pure dessert heaven.

How to Serve Peanut Butter Cup Dump Cake
This indulgent dessert is great on its own, but here are a few ways to elevate it even more:
- A Scoop of Ice Cream: A scoop of vanilla or chocolate ice cream is the perfect way to cool down the warm, gooey cake.
- Whipped Cream: Top with a dollop of freshly whipped cream for a light, fluffy contrast to the rich cake.
- Fresh Berries: For a little pop of freshness, serve the cake with fresh berries like raspberries or strawberries. The tangy sweetness balances the richness of the cake beautifully.
- Drizzle of Chocolate Sauce: If you’re a chocolate lover, drizzle a bit of chocolate sauce over the top. The extra chocolate never hurt anyone, right?
Additional Tips
Here are some handy tips to make sure your Peanut Butter Cup Dump Cake turns out perfect:
- Don’t Stir: Resist the urge to stir the ingredients together. The beauty of a dump cake is that the layers remain distinct, creating a gooey, melty center.
- Add More Peanut Butter Cups: If you’re feeling extra indulgent, you can always add more peanut butter cups to the mix. More chocolate and peanut butter? Yes, please!
- Try Different Cake Mix Flavors: Want to change things up? You can swap the cake mix for other flavors, like chocolate, vanilla, or even a spice cake mix for something unique.
- Storage Tips: Store leftovers in an airtight container for up to 3 days. Reheat in the microwave for 20-30 seconds for a quick fix when the craving strikes.
