What is a Dump Cake?

There’s no need for mixing or elaborate preparation. It’s one of the simplest yet most satisfying desserts, and the Peanut Butter Cup Dump Cake version takes this concept to the next level by combining rich chocolate, creamy peanut butter, and chunks of peanut butter cups for that perfect dessert indulgence.

Peanut Butter Cup Dump Cake is an easy, no-fuss dessert that’s a big hit with anyone who loves peanut butter and chocolate combinations. Think of it as the ultimate lazy dessert—no complex steps, just pure, comforting flavor.

Ingredients for Peanut Butter Cup Dump Cake

Before we start, let’s gather all the ingredients you’ll need to create this indulgent treat. Fortunately, these ingredients are simple, and you may already have most of them in your pantry.

Here’s what you’ll need:

1 box chocolate cake mix
The foundation of the cake, providing that signature chocolate flavor and moisture. A box mix keeps this recipe simple and foolproof.
1 (3.9 oz) box instant chocolate pudding mix
The pudding mix creates a creamy, custardy layer that pairs beautifully with the cake mix and adds an extra indulgent texture.
2 cups whole milk
Helps combine the pudding mix and creates a smooth, creamy texture when mixed with the pudding.
½ cup creamy peanut butter
The star ingredient! This adds the rich peanut flavor that pairs so wonderfully with chocolate.
½ cup butter, melted
Melting the butter helps it spread evenly over the top of the cake and adds richness to the dessert.
1 cup mini peanut butter cups, chopped
These peanut butter cups are the perfect bite-sized additions to this dump cake, adding a chewy and peanut butter-packed crunch.
1 cup milk chocolate chips
More chocolate! The chips melt into the cake, giving it a gooey, decadent texture.
½ cup chopped peanuts (optional for crunch)
If you love a bit of extra crunch, add some chopped peanuts on top. They also bring a slight salty contrast to the sweetness.
Whipped cream or vanilla ice cream (for serving)
Serve your warm, gooey peanut butter dump cake with a dollop of whipped cream or a scoop of vanilla ice cream to take it to the next level.

Dietary Substitutions:

Dairy-Free: To make this recipe dairy-free, swap the butter for dairy-free butter and use a plant-based milk like almond or oat milk. Choose dairy-free peanut butter cups or omit them if necessary.
Gluten-Free: Opt for a gluten-free chocolate cake mix to make this dessert gluten-free, and you’ll still enjoy all the deliciousness without any gluten-related concerns.

Instructions for Making Peanut Butter Cup Dump Cake

Now that we’ve gathered our ingredients, let’s go over the simple steps to create this mouthwatering Peanut Butter Cup Dump Cake. It’s almost too easy to make, but the results are truly impressive.

Step 1: Preheat the Oven

Start by preheating your oven to 350°F (175°C). This ensures that the cake bakes evenly and reaches the perfect gooey texture. While the oven is heating up, lightly grease a 9×13-inch baking dish to prevent any sticking and make cleanup easier later on.

Step 2: Prepare the Pudding Base

In a mixing bowl, whisk together the instant chocolate pudding mix and milk. Keep stirring until the mixture thickens, which should take about 2 minutes. Once it’s thickened, pour the pudding mixture evenly into the prepared baking dish, creating the first decadent layer of this dump cake.

Step 3: Add the Cake Mix

Next, take the dry chocolate cake mix and evenly sprinkle it over the pudding layer in the baking dish. Do not stir the cake mix—just let it rest on top of the pudding. This will create a beautiful texture as it bakes, with parts of the cake mix soaking up the pudding, while others remain slightly crispy on top.

Step 4: Drizzle the Peanut Butter

To give the cake its signature peanut butter flavor, warm the peanut butter slightly in the microwave for about 20-30 seconds or until it becomes more pourable. Drizzle the melted peanut butter evenly over the dry cake mix. This will infuse the cake with peanut flavor and help create a rich, gooey texture.

Step 5: Add the Butter

Now, drizzle the melted butter evenly over the cake mix and peanut butter layers. The butter will help bring everything together and give the cake its deliciously moist consistency.

Step 6: Top with Peanut Butter Cups and Chocolate Chips

This is the fun part! Sprinkle chopped mini peanut butter cups and milk chocolate chips over the top of the cake. These will melt into the cake, adding little pockets of gooey peanut butter and chocolate. If you’re a fan of a little extra crunch, feel free to sprinkle chopped peanuts over the top as well.

Step 7: Bake and Serve

Place the baking dish in the preheated oven and bake for 35-40 minutes or until the cake is bubbly and set. You’ll know it’s done when the edges are golden brown, and the center is firm but still a little gooey.

Once it’s finished baking, remove the cake from the oven and allow it to cool for a few minutes before serving. This is the perfect time to scoop out some whipped cream or vanilla ice cream to serve on the side.

Enjoy the warm, gooey, chocolate-peanut butter goodness of your Peanut Butter Cup Dump Cake—trust us, this dessert is going to disappear fast!

Tips for Making the Best Peanut Butter Cup Dump Cake

Use high-quality ingredients: Since this recipe relies on a few simple ingredients, using high-quality chocolate and peanut butter makes a big difference in flavor. Opt for a premium chocolate cake mix and real creamy peanut butter for the best results.
Don’t stir the cake mix: As tempting as it may be to mix the cake mix with the pudding and peanut butter layers, don’t! Let the layers remain separate, as they will naturally combine and create the best texture while baking.
Let the cake rest: After baking, allow the cake to rest for a few minutes before serving. This helps it set and makes it easier to scoop.
Add a personal twist: Feel free to add your own twist to this recipe. You could use dark chocolate chips instead of milk chocolate or throw in some caramel bits for an extra layer of sweetness.
Serve warm: For the best experience, serve this cake warm with a scoop of vanilla ice cream or a dollop of whipped cream.
