Ingredients
Dry Ingredients:
- 1 box chocolate cake mix
- 1 box instant chocolate pudding mix (3.9 oz)
Wet Ingredients:
- 2 cups milk
- 1/2 cup melted unsalted butter
Flavor & Toppings:
- 1 cup creamy peanut butter
- 1 cup mini peanut butter cups, halved
- 1 cup chocolate chips
- 1/2 cup chopped roasted peanuts
Step-by-Step Directions
1. Preheat & Prepare the Baking Dish
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish to prevent sticking.
2. Prepare the Pudding Layer
In a mixing bowl, whisk together the instant pudding mix and milk until it thickens, about 2 minutes. Pour the pudding mixture evenly into the baking dish.
3. Add the Peanut Butter
Drop spoonfuls of creamy peanut butter over the pudding layer. Use a spatula to gently spread it, ensuring even distribution.
4. Layer the Cake Mix
Evenly sprinkle the dry chocolate cake mix over the pudding and peanut butter layers. Avoid stirring—it will bake into a delicious, fudgy texture.
5. Add the Butter
Drizzle melted butter evenly over the dry cake mix. Ensure most of the dry mix is moistened for even baking.
6. Top It Off
Scatter mini peanut butter cups, chocolate chips, and chopped peanuts over the top. This adds texture and enhances the peanut butter-chocolate flavor.
7. Bake
Place the dish in the oven and bake for 35-40 minutes, or until the edges are bubbly and the top is set. The center should be slightly gooey.
8. Cool & Serve
Allow the cake to cool slightly before serving. For the best experience, serve warm with a scoop of vanilla ice cream or a drizzle of chocolate syrup.
Expert Tips for Best Results
- For a gooier texture, swirl an extra 1/4 cup of peanut butter into the pudding layer before baking.
- Use crunchy peanut butter for added texture.
- Drizzle butter slowly, making sure most of the cake mix is moistened to avoid dry patches.
- Let the cake rest for 10 minutes after baking to help it set while keeping the center gooey.
This Peanut Butter Cup Dump Cake is the perfect balance of chocolate, peanut butter, and crunch. With minimal effort and simple ingredients, it’s a crowd-pleasing dessert that’s sure to become a favorite.
Serving Suggestions
This Peanut Butter Cup Dump Cake is best enjoyed warm, straight from the oven. The rich chocolate and peanut butter flavors shine when paired with complementary toppings and side dishes. Here are a few ways to serve and enhance this indulgent dessert.
1. Classic Vanilla Ice Cream
A scoop of vanilla ice cream is the perfect pairing for this warm and gooey cake. The cold, creamy texture contrasts beautifully with the rich, fudgy layers.
2. Whipped Cream
A dollop of freshly whipped cream adds a light and airy element that balances out the dense and decadent cake. For extra flavor, add a touch of vanilla extract or a sprinkle of cocoa powder.
3. Drizzled Chocolate or Caramel Sauce
Enhance the chocolate and peanut butter flavors by drizzling warm chocolate ganache or caramel sauce over the top. This adds an extra layer of sweetness and makes the cake even more indulgent.
4. Crushed Pretzels or Graham Crackers
For a salty-sweet contrast, sprinkle crushed pretzels or graham crackers over the cake just before serving. This adds a slight crunch that complements the soft texture of the cake.
5. Fresh Berries
The natural tartness of strawberries, raspberries, or blackberries helps cut through the richness of the dessert. Serve a handful on the side or as a topping.
6. Espresso or Coffee
A strong cup of espresso or black coffee balances the sweetness of the cake, making it an excellent pairing for those who enjoy a less sugary contrast.
7. Peanut Butter Drizzle
For an extra peanut butter boost, melt a few tablespoons of peanut butter and drizzle it over the cake before serving. This enhances the peanut butter flavor and adds another creamy element.
8. Roasted Nuts
Chopped roasted peanuts, almonds, or pecans add extra crunch and a nutty depth that works well with the chocolate and peanut butter layers.
Common Mistakes to Avoid & How to Perfect the Recipe
Even though this recipe is simple, small mistakes can affect the final texture and flavor. Here’s what to watch out for:
1. Not Spreading the Peanut Butter Evenly
If the peanut butter is dropped in large clumps without spreading, some bites may be overly rich while others may lack flavor. Use a spatula to spread it slightly over the pudding layer for even distribution.
2. Leaving Too Much Dry Cake Mix Uncovered
Since the cake mix is sprinkled on top without being fully mixed in, it’s important to ensure that most of it gets moistened. Drizzle melted butter evenly over the cake mix to prevent dry spots.
3. Overbaking the Cake
The goal is to have a slightly gooey, molten center. Baking for too long can dry out the pudding layer, making the cake less fudgy. Bake just until the edges are bubbling and the top is set.
4. Using the Wrong Type of Pudding Mix
This recipe requires instant chocolate pudding mix rather than cook-and-serve pudding. Using the wrong type can affect the texture and consistency of the dessert.
5. Not Letting the Cake Rest Before Serving
While it’s tempting to dig in right away, allowing the cake to sit for 10 minutes after baking helps it set while still keeping the center warm and gooey.
6. Using Low-Fat Peanut Butter
Low-fat or natural peanut butter tends to separate when baked, affecting the consistency of the dessert. Stick with regular creamy or crunchy peanut butter for the best results.
7. Skipping the Toppings
The toppings—mini peanut butter cups, chocolate chips, and chopped peanuts—add extra texture and enhance the flavor. Don’t skip them if you want the full experience.
8. Storing the Cake Improperly
Leftover cake should be stored properly to maintain its texture. Store it in an airtight container at room temperature for up to 2 days, or refrigerate it for up to 5 days.
This Peanut Butter Cup Dump Cake is already delicious on its own, but serving it with the right sides and avoiding common mistakes ensures the best possible experience. Whether you enjoy it warm with ice cream or topped with caramel sauce, this dessert is guaranteed to satisfy any chocolate and peanut butter craving.
Recipe Tips, Storage, and Reheating Instructions
Expert Tips for the Best Dump Cake
- Use Room-Temperature Ingredients – Cold milk or peanut butter straight from the fridge can cause uneven baking. Let them sit at room temperature for about 10 minutes before using.
- Don’t Stir the Layers – This cake bakes in layers, creating a gooey center and a crisp topping. Stirring will change the texture and may prevent it from setting correctly.
- Adjust the Sweetness – If you prefer a less sweet dessert, use a dark chocolate cake mix or bittersweet chocolate chips to balance the flavors.
- Try Different Peanut Butter Varieties – Crunchy peanut butter adds texture, while flavored peanut butters, like honey-roasted or chocolate peanut butter, can bring a unique twist.
- Let It Rest Before Serving – Allowing the cake to sit for at least 10 minutes after baking helps it firm up slightly while keeping the center soft and gooey.
Storage Instructions
Proper storage helps maintain the texture and flavor of this cake.
- At Room Temperature: Store the cake in an airtight container or cover the baking dish with plastic wrap. It will stay fresh for up to 2 days.
- In the Refrigerator: For longer storage, keep the cake refrigerated for up to 5 days. The chilled texture will be firmer, but the cake can be warmed up before serving.
- In the Freezer: Wrap individual portions in plastic wrap and store them in a freezer-safe container for up to 3 months.
Reheating Instructions

FAQs
Can I Make This Cake in a Slow Cooker?
Yes. To make this in a slow cooker, follow the layering steps and cook on low for 2.5 to 3 hours or on high for 1.5 to 2 hours. The cake will be extra gooey with a softer texture.
Can I Use a Different Cake Mix Flavor?
Absolutely. While chocolate cake mix pairs best with peanut butter, you can experiment with devil’s food cake, yellow cake mix, or even brownie mix for a richer variation.
What Can I Use Instead of Peanut Butter?
If you have a peanut allergy or want to try something different, substitute peanut butter with almond butter, cashew butter, or Nutella for a unique twist.
Can I Make This Cake Without Pudding Mix?
Yes, but the pudding mix adds moisture and richness to the cake. If you leave it out, consider adding an extra ¼ cup of milk or a drizzle of sweetened condensed milk for a similar effect.
Why Is My Cake Still Wet in the Middle?
This cake is supposed to be gooey, but if it seems undercooked, it may need more time in the oven. Cover it with foil and bake for an additional 5-10 minutes.
Can I Use Crunchy Peanut Butter Instead of Creamy?
Yes. Crunchy peanut butter adds extra texture and enhances the nutty flavor.
