Ingredients You’ll Need
Gathering just a handful of straightforward ingredients is all it takes to whip up this scrumptious dessert. Each one plays a crucial role in building a perfect balance of taste, texture, and that irresistible color that makes this cake so inviting.
- Chocolate cake mix: The base that provides structure and deep chocolate flavor to this layered dessert.
- Instant chocolate pudding mix: Adds luscious creaminess that melts into the cake for added moisture and richness.
- Whole milk: Used to thicken the pudding, contributing to that silky smooth texture.
- Creamy peanut butter: Warmed and drizzled over the cake mix, infusing a nutty, rich essence throughout.
- Butter, melted: Creates a golden, crisp top layer and adds indulgent richness.
- Mini peanut butter cups, chopped: Scattered across the top to provide bursts of peanut butter and chocolate goodness.
- Milk chocolate chips: Sprinkle them on for melty chocolate pockets inside the cake.

How to Make Peanut Butter Cup Dump Cake: A Decadent Dessert Recipe
Step 1: Prepare Your Pan and Pudding Layer
Start by preheating your oven to 350°F (175°C) and lightly greasing a 9×13-inch baking dish so the cake doesn’t stick. Whisk the instant chocolate pudding mix into whole milk until it thickens, which takes about two minutes; this decadent pudding layer becomes the moist and creamy foundation for the dessert.
Step 2: Layer the Cake Mix
Once your pudding is ready and settled into the pan, sprinkle the dry chocolate cake mix evenly on top. The key here is not to stir—keeping the layers separate allows the unique textures to shine through as it bakes.
Step 3: Drizzle Peanut Butter and Butter
Warm the creamy peanut butter slightly so it’s easy to drizzle, then spread it generously over the cake mix. Follow with an even drizzle of melted butter to encourage a perfect, golden crust and infuse the cake with rich buttery notes.
Step 4: Add the Toppings
Scatter the chopped mini peanut butter cups, milk chocolate chips, and if you like extra crunch, sprinkle on some chopped peanuts. These toppings melt together beautifully during baking, creating irresistible pockets of gooey, nutty goodness.
Step 5: Bake Until Golden and Bubbly
Pop your pan into the oven and bake for 35 to 40 minutes. You’ll know it’s done when the top turns golden brown and is bubbling with melted chocolate and peanut butter nuggets peeking through.
Step 6: Serve Warm and Enjoy
This cake is best enjoyed warm, straight from the oven. Add a big dollop of whipped cream or a scoop of vanilla ice cream on the side to complement its rich flavors and take indulgence to the next level.

FAQs
Can I use crunchy peanut butter instead of creamy?
Absolutely! Using crunchy peanut butter will add extra texture to the dessert, enhancing the nutty experience. Just note that it might be a little chunkier when drizzled over the cake mix layer.
Is it necessary to use instant pudding mix?
The instant pudding mix helps create that smooth, creamy layer that keeps the cake moist and decadent. You could try homemade pudding, but the instant mix makes the process much quicker and foolproof.
Can this recipe be made gluten-free?
Yes, you can substitute gluten-free chocolate cake mix to accommodate gluten sensitivities. Just ensure all other ingredients are gluten-free as well, like the pudding mix and chocolate chips.
What if I don’t have mini peanut butter cups?
No worries—chop up regular peanut butter cups or even use Reese’s Pieces for a fun twist. The goal is to add that peanut butter and chocolate flavor burst in every bite.
Can I make this cake ahead of time?
Definitely! You can assemble the cake up to a day before baking and keep it refrigerated. Just add a few extra minutes to the baking time since the ingredients will be chilled.
