Ingredients
The magic of Peanut Butter Cup Dump Cake comes from a short list of simple ingredients that work together to create layers of flavor and texture.
1 box (15.25 oz / 432 g) chocolate cake mix
1 cup (240 ml) milk
½ cup (115 g) unsalted butter, melted
1 cup (200 g) creamy peanut butter
1 cup (180 g) mini peanut butter cups, halved
½ cup (90 g) chocolate chips
½ cup (120 ml) sweetened condensed milk
1 tsp vanilla extract
¼ tsp salt
Optional toppings:
½ cup whipped cream or vanilla ice cream
2 tbsp chocolate syrup
2 tbsp crushed peanut butter cups
The cake mix forms the base layer, while peanut butter and condensed milk add creamy richness. Peanut butter cups melt into the cake during baking, giving Peanut Butter Cup Dump Cake its signature gooey pockets of chocolate and peanut butter.
Pro Tips
Great dump cakes rely on layering and timing. These tips help you create the perfect Peanut Butter Cup Dump Cake every time.
Distribute the Butter Evenly
Pour melted butter slowly over the cake mix layer so it spreads across the surface. This step ensures the top bakes into a golden, slightly crisp crust rather than dry powder patches.
Use Chopped Peanut Butter Cups
Cut peanut butter cups in halves or quarters before adding them. Smaller pieces melt more evenly and create delicious pockets of creamy peanut butter flavor throughout the cake.
Do Not Overmix
Dump cakes work best when ingredients stay layered. Avoid stirring everything together. Let the oven naturally combine the flavors while baking.
Following these techniques helps you achieve the perfect gooey center and crisp topping that makes Peanut Butter Cup Dump Cake so irresistible.
Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or cooking spray to prevent sticking.
Step 2: Prepare the Base Layer
In a medium bowl, whisk together milk, peanut butter, vanilla extract, and sweetened condensed milk until smooth. Pour this mixture evenly into the prepared baking dish.
Step 3: Add the Peanut Butter Cups
Sprinkle halved peanut butter cups and chocolate chips evenly across the mixture. This step creates the signature gooey chocolate-peanut butter pockets.
Step 4: Add the Cake Mix
Carefully sprinkle the chocolate cake mix evenly across the top. Do not stir. The dry mix will bake into a tender cake layer.
Step 5: Pour the Butter
Slowly drizzle melted butter across the cake mix, covering as much of the surface as possible. This step creates the golden crust that makes Peanut Butter Cup Dump Cake so delicious.
Step 6: Bake the Cake
Place the baking dish in the oven and bake for 40–45 minutes. The top should appear golden and slightly crisp while the center remains soft.
Step 7: Cool Slightly
Allow the cake to rest for about 10 minutes. This helps the layers settle and makes serving easier.
Step 8: Serve Warm
Scoop generous portions into bowls and top with vanilla ice cream or whipped cream for the ultimate dessert experience.
Fresh from the oven, Peanut Butter Cup Dump Cake delivers a rich combination of melted candy, fluffy cake, and warm chocolate flavor.
Variations
One of the best things about Peanut Butter Cup Dump Cake is how easily you can customize it.
Peanut Butter Brownie Dump Cake
Replace the chocolate cake mix with brownie mix for a richer texture similar to peanut butter brownie bars.
Salted Caramel Version
Add ¼ cup caramel sauce and a pinch of flaky sea salt before baking. The caramel pairs beautifully with peanut butter and chocolate.
Crunchy Peanut Butter Version
Swap creamy peanut butter for crunchy peanut butter. This adds small peanut pieces that create extra texture in every bite.
These variations allow you to adapt Peanut Butter Cup Dump Cake to match your favorite chocolate and peanut butter combinations.
Storage and Serving Suggestions
Store leftover Peanut Butter Cup Dump Cake in an airtight container in the refrigerator for up to four days. The flavors actually deepen overnight, making the dessert even richer the next day.
To reheat, warm individual portions in the microwave for about 15–20 seconds. This restores the gooey chocolate texture and soft cake layers.
For serving, scoop the warm cake into dessert bowls and add vanilla ice cream. The cold ice cream melts into the warm cake and creates a creamy sauce.
You can also drizzle chocolate syrup, caramel sauce, or peanut butter sauce over the top. For parties, garnish with chopped peanut butter cups and whipped cream for a bakery-style presentation.
