Ingredients Breakdown
To create the Peanut Butter Cup Dump Cake, you’ll need a few basic ingredients. These ingredients work together to create the perfect balance of chocolatey and peanut buttery flavors. Here’s a breakdown of what you’ll need and how each ingredient contributes to the overall taste and texture:
-
Chocolate Cake Mix (15.25 oz box)
The foundation of this cake is a chocolate cake mix. This provides the base layer of the dessert, giving it that rich, moist texture. You don’t need to worry about adding any eggs, oil, or other typical cake ingredients; the dry cake mix does it all. The cake mix is essential for creating the soft, gooey texture that characterizes this dessert. -
Peanut Butter (Smooth or Crunchy)
The peanut butter is what gives this dump cake its signature flavor. You can choose between smooth or crunchy peanut butter depending on your preference. The smooth variety creates a more uniform, creamy texture, while the crunchy variety adds an extra texture contrast with bits of peanuts. Both options will melt perfectly into the cake, enhancing the flavor with a rich, nutty undertone. -
Milk Chocolate Chips
These chocolate chips are sprinkled over the peanut butter to create an extra chocolatey layer. As they bake, the chips melt, blending into the peanut butter and forming a delicious gooey texture. Milk chocolate chips are the ideal choice here, as they add sweetness that balances out the richness of the peanut butter. -
Mini Peanut Butter Cups (Chopped)
For the ultimate peanut butter cup experience, we add chopped mini peanut butter cups into the mix. These cups melt beautifully as they bake, contributing to the overall gooeyness and adding bites of creamy peanut butter filling. You can use Reese’s mini peanut butter cups or any other brand, depending on your preference. The chocolate and peanut butter ratio in each mini cup will make each bite feel like a mini dessert on its own. -
Unsalted Butter (½ cup, melted)
The melted butter is poured over the cake mix to help bind the ingredients together and create a soft, golden crust. It also adds moisture and richness to the dessert. Unsalted butter is recommended, as it allows the peanut butter and chocolate flavors to shine without being overpowered by salt. -
Water (1 ½ cups)
Water is added to the cake mix to activate the dry ingredients and ensure the cake doesn’t dry out during baking. The combination of water and melted butter gives the cake its moist texture and makes sure the cake layers form properly during the baking process.
Each of these ingredients works in harmony to create a perfectly balanced dessert. There’s no need to worry about measuring anything with precision—just follow the recipe, dump the ingredients, and bake!

Step-by-Step Instructions
Creating this Peanut Butter Cup Dump Cake is as easy as dumping the ingredients into a baking dish and letting the oven do the rest! Follow these steps for a delicious dessert that will wow your guests:
-
Preheat Your Oven
Set your oven to 350°F (175°C). Preheating ensures that your cake bakes evenly and helps to develop that golden crust you want at the edges of the cake. -
Prepare the Baking Dish
Grease a 9×13-inch baking dish with butter or non-stick spray. This helps prevent the cake from sticking to the dish during baking, making cleanup a breeze. -
Layer the Dry Cake Mix
Spread the dry chocolate cake mix evenly over the bottom of the prepared baking dish. There’s no need to mix the dry cake mix with any other ingredients. Simply spread it out flat and evenly across the pan. -
Add Peanut Butter Dollops
Spoon dollops of peanut butter across the top of the dry cake mix. Don’t worry about spreading it out evenly—some gaps are fine. The peanut butter will melt during baking and spread naturally, adding to the gooey texture of the dessert. -
Sprinkle Chocolate Chips and Peanut Butter Cups
Evenly distribute the milk chocolate chips and chopped mini peanut butter cups on top of the peanut butter. These ingredients will melt into the cake as it bakes, creating a rich, chocolatey and peanut butter-filled layer. -
Pour Melted Butter and Water
Drizzle the melted butter evenly over the top of the cake mix and other ingredients. Then, pour the water over the entire mixture. Do not stir or mix the ingredients—just let them sit on top. The water will create a nice, moist cake while the butter helps to form a golden, crispy crust around the edges. -
Bake the Cake
Place the baking dish into the preheated oven and bake for 40-45 minutes. Keep an eye on the cake toward the end of the baking time. The cake should be set in the center, with golden-brown edges and a gooey top layer. If the edges are overly crispy, remove the cake from the oven. -
Cool and Serve
Let the Peanut Butter Cup Dump Cake cool for about 10 minutes before serving. This helps the dessert firm up a bit, making it easier to serve. Once cool, you can cut it into squares or serve it in larger chunks.

Tips for the Best Peanut Butter Cup Dump Cake
While the Peanut Butter Cup Dump Cake is easy to make, there are a few tips and tricks that can ensure you get the best results every time. With these simple adjustments, you can make your cake even more flavorful and tailor it to your specific preferences.
1. Choosing the Right Peanut Butter
The type of peanut butter you use can make a big difference in the texture and taste of your cake. You can choose between smooth or crunchy peanut butter, depending on your personal preference.
-
Smooth peanut butter will give the cake a silky, uniform texture, blending seamlessly with the chocolate and cake mix.
-
Crunchy peanut butter adds a bit more texture and bite, creating a more dynamic experience as you eat. The crunchy bits add a nice contrast to the soft cake and melty chocolate.
2. Customize with Different Chocolate Types
While milk chocolate chips work perfectly in this cake, you can swap them out for different types of chocolate for a more unique flavor:
-
Dark chocolate chips give the cake a deeper, more sophisticated flavor, which balances well with the sweetness of the peanut butter.
-
White chocolate chips add a creamy sweetness that complements the peanut butter without overpowering it.
3. Baking Time and Texture
The baking time for this cake is important for achieving the right texture. You want the cake to be set in the center but still gooey and slightly undercooked in the middle. Keep an eye on the cake towards the end of baking:
-
If the edges start to get too dark before the center is fully set, cover the dish loosely with foil and continue baking until done.
-
For a slightly firmer cake, you can bake it a little longer—just be sure not to overbake, or it may become dry.
4. Serving Suggestions
While this cake is amazing on its own, it can be enhanced with a few toppings to make it even more decadent:
-
Vanilla ice cream or whipped cream on top is a perfect addition, adding a creamy, cool contrast to the warm, rich cake.
-
For a festive touch, top with crushed candy canes for Christmas, or colorful sprinkles for a birthday party.
5. Make Ahead Tips
If you’re preparing for a party or gathering, you can make the Peanut Butter Cup Dump Cake ahead of time and reheat it just before serving. To do so, store it in an airtight container in the fridge. Reheat in the oven or microwave, and add a dollop of whipped cream or ice cream just before serving.
