- Chocolate Cake Mix: An easy shortcut that gives the cake its classic chocolate base and fluffy texture.

- Melted Butter: Adds rich moisture to the batter, making each slice wonderfully tender.

How to Make peanut butter cup dump cake delight
Step 1: Preheat and Prepare
Turn your oven to 350°F (175°C) and let it preheat while you grab a 9×13-inch baking dish. Grease the dish thoroughly—this ensures your cake slices come out perfectly every time, without any sticking or crumbling.
Step 2: Layer the Peanut Butter
Take that glorious cup of peanut butter and use a spatula to spread it smoothly across the bottom of your prepared dish. This creamy base layer will create magic as it bakes, giving each square an irresistible swirl of peanut butter.
Step 3: Mix the Batter
In a medium mixing bowl, pour in the chocolate cake mix. Add the melted butter and milk, then stir it all together until you have a silky, lump-free batter. The buttery richness makes this cake extra special.
Step 4: Assemble the Cake
Carefully pour the chocolate batter over your peanut butter layer, spreading it gently with a spatula so it covers every inch. This layering keeps the peanut butter separate in pockets beneath the cake, ready for that perfect scoop.
Step 5: Add the Toppings
Generously scatter the mini peanut butter cups and chocolate chips over the top of your batter. As the cake bakes, these goodies will melt into the cake and slightly crisp on the surface for a delicious texture contrast.
Step 6: Bake and Finish
Pop the whole pan into your preheated oven and bake for 35-40 minutes. You’ll know it’s done when a toothpick inserted in the center comes out mostly clean (a few moist crumbs are fine!). Allow your peanut butter cup dump cake delight to cool completely before slicing—this patience pays off with perfect, clean servings.
How to Serve peanut butter cup dump cake delight

Garnishes
Try topping each slice with a scoop of vanilla ice cream, a drizzle of chocolate or caramel sauce, or even a few more chopped peanut butter cups for good measure. A dollop of whipped cream adds a light, fluffy contrast to the cake’s richness.
Side Dishes
Pair your peanut butter cup dump cake delight with fresh strawberries or sliced bananas for a fruity touch. For a touch of salt, consider serving alongside salted pretzels or potato chips—trust me, the sweet-and-salty combo is unexpectedly amazing.
Creative Ways to Present
Cut the cake into cute squares and skewer them with small sticks to create dessert kabobs. Or, serve slightly warm in individual bowls, topped with ice cream for a peanut butter cup dump cake delight sundae bar at your next gathering!
Make Ahead and Storage
Storing Leftovers
To keep your cake fresh, cover the baking dish tightly with foil or plastic wrap, or transfer leftovers to an airtight container. Store in the refrigerator for up to 4-5 days—those delicious fudgy flavors will deepen as it sits!
Freezing
Your peanut butter cup dump cake delight freezes beautifully. Slice the cooled cake, wrap individual pieces in plastic wrap, and place them in a freezer-safe bag for up to 2 months. Thaw in the refrigerator or at room temperature before serving.
Reheating
If you love a warm, gooey dessert, pop a slice in the microwave for about 20-30 seconds before serving. This softens the cake and melts the peanut butter cups again—just like fresh-baked!
FAQs
Can I use a different type of cake mix?
Absolutely! While chocolate is classic for peanut butter cup dump cake delight, you can swap in devil’s food, fudge, or even a yellow cake mix for a slightly different but equally delicious effect.
Is it possible to make this gluten-free?
Yes—simply use a gluten-free chocolate cake mix and double-check that your mix-ins are certified gluten-free. The texture and flavor will still be fantastic.
Do I need to melt the peanut butter before spreading?
No need! Regular creamy peanut butter spreads easily over the greased dish, but if it’s especially firm, 10 seconds in the microwave will help smooth it out.
Can I make this ahead for a party?
Definitely! Bake your peanut butter cup dump cake delight in advance, cover, and chill. It tastes just as good cold or at room temperature and slices even neater after cooling down.
What else can I add on top?
Feel free to experiment—try chopped peanuts, caramel bits, mini marshmallows, or even a sprinkle of sea salt on top to make your peanut butter cup dump cake delight your own!
