Ingredients You’ll Need

Every ingredient in this Peanut Butter Cup Dump Cake is chosen for maximum flavor and the perfect mix of textures. The best part? You probably already have many of these pantry staples at home, and a few candy aisle treats will make this cake unforgettable.

Yellow Cake Mix: The secret shortcut to creating a fluffy, golden, bake-shop worthy topping with hardly any effort.
Creamy Peanut Butter: Adds richness and that classic nutty flavor we all love—don’t skimp on this layer!
Sweetened Condensed Milk: Gives the cake its luscious, gooey consistency and just the right amount of sweetness.
Mini Peanut Butter Cups, Chopped: Brings bursts of chocolate-peanut butter goodness to every bite; use your favorite brand.
Chocolate Chips: Melt into the base and swirl throughout, ensuring chocolatey decadence in every forkful.
Butter, Melted: Helps the cake mix form that dreamy, slightly crisp top and keeps every bite tender.
Chopped Reese’s or Other Peanut Butter Candies: Extra candy bits on top make each serving a true celebration for peanut butter fans.
Chocolate Syrup (optional, for drizzling): The finishing flourish for anyone who loves a little more chocolate drama.

How to Make Peanut Butter Cup Dump Cake

Step 1: Prep Your Baking Dish

Start by preheating your oven to 350°F (175°C), then lightly grease a 9×13-inch baking dish with butter or your favorite nonstick spray. Taking this step now means you’ll be ready for effortless cake assembly and a perfectly baked result with nothing sticking to the pan.

Step 2: Layer the Chocolate and Peanut Butter Candy

Scatter your chopped mini peanut butter cups and chocolate chips evenly over the bottom of the dish. This creates a chocolatey, gooey foundation that softens and melts as the cake bakes!

Step 3: Add the Sweetened Condensed Milk

Time to pour! Drizzle the sweetened condensed milk right over the candy layer, making sure to coat as evenly as possible. This is what gives Peanut Butter Cup Dump Cake its signature gooey texture.

Step 4: Dollop with Creamy Peanut Butter

Using a spoon, dollop the creamy peanut butter across the dish. You don’t need to mix or spread—just let it sit in little pools across the surface. As it bakes, the peanut butter will melt into the cake, infusing every bite with that irresistible flavor.

Step 5: Sprinkle the Cake Mix

Now sprinkle the yellow cake mix evenly over everything. Don’t stir it in—just let it create a lovely, crumbly layer on top. This is the “dump” part of the dump cake, and the magic happens as it bakes.

Step 6: Pour on the Butter

Evenly pour your melted butter over the entire surface. This gives the cake its fabulous buttery crust and keeps the top tender while helping the cake mix cook to golden perfection.

Step 7: Bake and Finish

Slide your dish into the preheated oven and bake for 40–45 minutes. The top should be golden brown and bubbling around the edges. Let your Peanut Butter Cup Dump Cake cool slightly, then finish with extra chopped candies and a generous drizzle of chocolate syrup if you like. Dessert perfection!

How to Serve Peanut Butter Cup Dump Cake

Garnishes

For that extra bakery-worthy wow factor, sprinkle a handful of chopped Reese’s or your favorite peanut butter candies on top after baking. A drizzle of chocolate syrup puts each piece over the top, and a little sprinkle of flaky sea salt can add a surprising and delicious contrast.

Side Dishes

This rich dessert shines on its own, but a scoop of vanilla ice cream or a dollop of whipped cream cools things down and gives you a beautiful hot-and-cold combo. Pair it with an icy glass of milk or a strong cup of coffee, and you’ve got yourself the ultimate treat.

Creative Ways to Present

Take your Peanut Butter Cup Dump Cake to the next level by serving in mason jars or individual ramekins for the cutest personal portions. For parties, cut into bars or squares and stack them up on a pretty cake plate. Feeling extra? Top each jar or plate with a mini peanut butter cup for an adorable finishing touch.

Make Ahead and Storage

Storing Leftovers

Leftover Peanut Butter Cup Dump Cake keeps incredibly well! Cover the baking dish tightly with foil or transfer servings to an airtight container, then keep in the fridge for up to 4 days. It tastes just as dreamy cold, but is even better when gently warmed.

Freezing

For longer storage, you can freeze individual portions or the whole cake. Wrap slices in plastic wrap and foil, or use a freezer-safe container. It will keep its flavor and texture for up to 2 months—just make sure to thaw overnight in the fridge before reheating.

Reheating

To bring back that fresh-from-the-oven magic, reheat individual portions in the microwave for about 30 seconds, or pop the baking dish, covered with foil, into a 325°F oven until heated through. Don’t forget a fresh chocolate drizzle and a little extra candy for the ultimate second-day treat!

FAQs

Can I use a different cake mix flavor?

Absolutely! While yellow cake mix gives a buttery, classic flavor, feel free to swap in chocolate, devil’s food, or even white cake mix. Each will bring its own delicious twist to your Peanut Butter Cup Dump Cake.

Is it necessary to chop the peanut butter cups and candies?

Chopping them helps them distribute evenly and melt into every layer, but you can leave a few whole minis on top as a decorative touch if you like. The choice is yours!

Can I use crunchy peanut butter instead of creamy?

If you love a little extra texture, crunchy peanut butter works great. You’ll get delightful bits of peanut throughout, which can be a fun variation in your dump cake.

How do I know when the dump cake is fully baked?

The top should look golden brown and set, with some bubbling around the edges where the candies and condensed milk are doing their thing. If you gently shake the dish and the top stays mostly firm, it’s ready!

Can I make this Peanut Butter Cup Dump Cake gluten-free?

Yes! Just use your favorite gluten-free yellow or chocolate cake mix as a substitute and check that all the candy you add is gluten-free as well. The final result will be just as decadent and delicious.

Final Thoughts

If you love the magic of peanut butter and chocolate, this Peanut Butter Cup Dump Cake will steal your heart and save you time in the kitchen. It’s easy, fun, impossible to resist, and guaranteed to impress—give it a try and treat yourself and your loved ones to a dessert that’s pure joy in every scoop!
