When you want a rich, chocolatey dessert without complicated steps or fancy techniques, Peanut Butter Cup Dump Cake is the answer. This irresistible treat combines deep chocolate flavor, creamy peanut butter, and gooey cake layers—all made with a simple “dump and bake” method. No mixing bowls, no stress, and no baking expertise required.
Dump cakes have become incredibly popular in the United States, United Kingdom, and Canada because they deliver maximum flavor with minimal effort. This version, loaded with chocolate and peanut butter cups, takes the concept to the next level. Whether you’re hosting a party, craving a cozy dessert, or need a last-minute sweet treat, peanut butter cup dump cake never disappoints.
What Is a Dump Cake?
A Dessert Built for Simplicity
A dump cake is exactly what it sounds like—ingredients are “dumped” into a baking dish in layers and baked until bubbly and golden. There’s no need to mix the batter, making it one of the easiest desserts to prepare.
Why Peanut Butter Cup Dump Cake Stands Out
While classic dump cakes often feature fruit fillings, this version leans into pure indulgence. Chocolate cake mix, melted butter, and peanut butter cups combine to create a dessert that’s rich, gooey, and deeply satisfying.
Why Peanut Butter and Chocolate Are a Perfect Match
Chocolate and peanut butter are one of the most beloved flavor combinations in baking. The bitterness of cocoa balances the sweetness and saltiness of peanut butter, creating a dessert that feels rich without being overwhelming.
Using chopped Reese’s Peanut Butter Cups adds pockets of creamy peanut butter throughout the cake, ensuring every bite delivers that iconic flavor pairing.
Ingredients That Make This Dump Cake So Irresistible
Chocolate Cake Mix
A boxed chocolate cake mix forms the base of this dessert. It creates a soft, brownie-like texture once baked with butter and melted peanut butter cups.
Peanut Butter Cups
Chopped peanut butter cups melt slightly as the cake bakes, creating gooey layers of chocolate and peanut butter throughout.
Butter
Melted butter is poured over the cake mix, helping it bake evenly and develop a crisp, golden topping.
Optional Add-Ins
Many bakers like to enhance their peanut butter cup dump cake with:
Chocolate chips
Peanut butter chips
Sweetened condensed milk
Chopped peanuts
These additions make the cake even richer and more decadent.
How Peanut Butter Cup Dump Cake Comes Together
Step 1: Layer the Base
Peanut butter cups are spread across the bottom of a greased baking dish. This creates a molten chocolate-peanut butter layer once baked.
Step 2: Add the Cake Mix
Dry chocolate cake mix is evenly sprinkled over the peanut butter cups. No stirring required—this is the beauty of a dump cake.
Step 3: Pour the Butter
Melted butter is poured evenly over the cake mix, soaking into the dry ingredients and creating a rich, crumbly topping.
Step 4: Bake Until Gooey
As the cake bakes, the layers come together into a dessert that’s soft underneath with a slightly crisp top and pockets of melted peanut butter cups throughout.
Tips for the Best Peanut Butter Cup Dump Cake
Distribute Butter Evenly
Try to cover as much of the cake mix as possible with butter to avoid dry patches. This ensures a moist, evenly baked cake.
Don’t Overbake
The center should be soft and gooey when removed from the oven. Dump cakes firm up as they cool.
Let It Rest Before Serving
Allow the cake to cool for 10–15 minutes after baking. This helps the layers set slightly while keeping the center warm and molten.
Serve Warm for Maximum Impact
Peanut butter cup dump cake is best enjoyed warm, when the chocolate is still melted and the flavors are at their peak.
Serving Ideas and Pairings
This dessert is indulgent on its own, but pairing it with the right topping makes it unforgettable:
Vanilla ice cream for contrast
Whipped cream for a lighter finish
Chocolate or peanut butter drizzle
A sprinkle of crushed peanut butter cups
The warm cake paired with cold ice cream is especially popular for gatherings and celebrations.
Easy Variations to Try
Peanut Butter Lover’s Dump Cake
Add dollops of creamy peanut butter on top of the cake mix before baking for extra richness.
Triple Chocolate Version
Use chocolate fudge cake mix and add dark chocolate chunks or chocolate syrup.
No-Bake Inspiration
While dump cakes are baked, the flavors can inspire no-bake desserts like layered peanut butter cup parfaits or refrigerator cakes.
Gluten-Free Option
Use a gluten-free chocolate cake mix to make this dessert suitable for gluten-sensitive guests.
Storage and Make-Ahead Tips
Peanut butter cup dump cake can be stored in an airtight container in the refrigerator for up to 4 days. To reheat, warm individual portions in the microwave for 20–30 seconds.
This dessert can also be prepared a few hours ahead of serving and gently reheated before guests arrive.
