Ingredients You’ll Need
The magic of this Peanut Butter Cup Dump Cake Recipe lies in its simple yet thoughtfully chosen ingredients. Each one plays a vital role, from the creamy peanut butter adding luscious richness, to the chocolate cake mix delivering that soft, crumbly texture. Quality and balance are key here, so having these essentials on hand makes all the difference in building layers of flavor and texture.
- Chocolate cake mix: This forms the base and adds a moist, chocolaty crumb that ties everything together.
- Creamy peanut butter: Spread evenly to create a velvety, nutty layer beneath the cake mix.
- Sweetened condensed milk: Acts as a rich, caramel-like binder that keeps the dessert indulgently moist.
- Chopped peanut butter cups: These little pockets of chocolate and peanut butter bring bursts of sweet, nutty crunch throughout.
- Melted butter: Poured on top to help crisp the cake’s surface while adding buttery flavor.
- Milk chocolate chips: Sprinkled for melty chocolate bits that add extra gooeyness and sweetness.
- Optional: Whipped cream or vanilla ice cream: Perfect for serving to add creaminess and contrast the warm cake.
How to Make Peanut Butter Cup Dump Cake Recipe
Step 1: Preheat and Prepare
First things first—set your oven to 350°F (175°C) and grease a 9×13-inch baking dish. Greasing ensures the cake won’t stick and makes clean-up a breeze. This step lays the groundwork for your layers to bake beautifully without any worry.
Step 2: Create the Peanut Butter and Candy Base
Gently spread the creamy peanut butter evenly over the bottom of your prepared pan. This thick blanket not only adds incredible flavor but also keeps the dessert moist. Next, sprinkle half of the chopped peanut butter cups all over the peanut butter, sending waves of sweet, chocolatey, nutty goodness throughout the cake.
Step 3: Pour in the Sweetened Condensed Milk
Pour the entire can of sweetened condensed milk evenly over the peanut butter and candy layer. This luxurious milk creates a sticky, luscious layer that holds everything together and adds a lovely caramel-like sweetness.
Step 4: Add the Chocolate Cake Mix
Now sprinkle the dry chocolate cake mix evenly over the sweetened condensed milk. This creates the signature “dump cake” texture, where the dry mix bakes on top and softens just enough from the moisture beneath.
Step 5: Dot with Butter and Chocolate Chips
Drizzle the melted butter all over the cake mix to help it crisp up and develop a golden brown top while baking. After that, sprinkle the remaining chopped peanut butter cups along with the chocolate chips on top for an extra layer of texture and melting chocolate pleasure.
Step 6: Bake to Perfection
Pop your dish into the oven and bake for 35 to 40 minutes. Look for the top to become bubbly and lightly crisped, signaling that all those layers have melded together into one irresistible dessert.
Step 7: Cool and Serve
Once out of the oven, allow the cake to cool for 10 to 15 minutes. This resting time helps the layers set and makes it easier to serve generous, gooey slices. For an added touch of indulgence, serve warm with a dollop of whipped cream or a scoop of vanilla ice cream.
How to Serve Peanut Butter Cup Dump Cake Recipe

Garnishes
Sprinkling extra chopped peanut butter cups on top just before serving adds a delightful crunch and a visually tempting finish. A fresh dusting of powdered sugar or a drizzle of caramel sauce would also elevate this dessert into something truly special.
Side Dishes
This dump cake pairs wonderfully with light sides like fresh fruit, especially berries or sliced bananas, which balance the dessert’s richness. If you want to embrace decadence fully, a scoop of rich vanilla ice cream or a spoonful of cool whipped cream on the side never goes wrong.
Creative Ways to Present
For a party, consider serving individual portions in clear glass cups to showcase the gooey layers. Alternatively, add some crushed pretzels or toasted pecans on top for added texture and a salty twist. Personalizing presentation adds an extra bit of wow to this simple dessert.
Make Ahead and Storage
Storing Leftovers
Leftover Peanut Butter Cup Dump Cake Recipe keeps beautifully in an airtight container in the refrigerator for up to 3 days. The flavors deepen as it sits, making leftovers even tastier the next day. Just bring pieces to room temperature or warm slightly before serving.
Freezing
If you have extra cake, freeze it in portions wrapped tightly in plastic wrap, then foil, for up to 2 months. Thaw in the fridge overnight before reheating gently in the oven to restore that freshly baked texture and flavor.
Reheating
Reheat slices in a microwave-safe plate for 30 to 45 seconds, or keep them warm in a 300°F oven covered with foil for 10–15 minutes to soften up and bring back that gooey magic.
FAQs
Can I use crunchy peanut butter instead of creamy?
Absolutely! Crunchy peanut butter will add extra texture to your dump cake, giving it a little more bite. Just spread it as evenly as you can for the best results.
Is it possible to make this recipe nut-free?
This recipe relies heavily on peanut butter and peanut butter cups, so it’s tricky to make it nut-free without losing the signature flavor. However, you could experiment with sun butter and nut-free chocolate candies but expect a different taste.
Can I use homemade cake mix or flour instead?
While you can try substituting homemade cake mix or a flour mixture, the convenience and precise leavening of boxed cake mix work best to achieve that perfect texture for this dump cake.
What other candies could I use in place of peanut butter cups?
Feel free to get creative! Pieces of Reese’s Pieces, chocolate-covered pretzels, or even chopped Snickers bars could add unique twists to the flavor and texture.
How do I know when the cake is done baking?
The top should be bubbly and slightly crisp to the touch, with a golden brown color. You can also gently poke with a toothpick; a few moist crumbs are okay, as the cake is meant to be gooey.
