Step‑by‑Step Instructions for Peanut Butter Cup Dump Cake
Step 1: Preheat and Prep
Start by preheating your oven to 350°F (175°C). While it warms up, thoroughly grease a 9×13 inch baking dish to ensure easy removal of your Peanut Butter Cup Dump Cake. A non-stick spray or a light coating of butter works wonders here, creating a perfect base for our delicious layers.
Step 2: Spread the Peanut Butter
Once your dish is ready, take your peanut butter and spread it evenly across the bottom. This layer will serve as a rich, gooey foundation for your dump cake. Use a spatula for easy spreading, ensuring every inch is covered so that each bite is loaded with that delightful peanut butter goodness.
Step 3: Add the Cake Mix
Next, grab your boxed chocolate cake mix and carefully dump it over the peanut butter without mixing. This is a crucial step for achieving the signature dump cake texture. The dry mix will form a tasty layer that bakes into a light and fluffy cake, setting the stage for all that melted chocolate and peanut butter deliciousness.
Step 4: Pour the Liquids
Pour the melted butter and whole milk evenly over the cake mix layer. It’s important to distribute the liquids evenly; do not stir. This will allow the dry cake mix to absorb the moisture as it bakes, giving your Peanut Butter Cup Dump Cake its delightful texture.
Step 5: Add the Chocolate Treats
Now it’s time for the fun part! Sprinkle the mini peanut butter cups and chocolate chips generously over the top. Make sure they’re scattered well so that each slice of the cake is filled with melty chocolatey goodness. This topping will create beautiful pockets of flavor as it bakes and melts into the cake.
Step 6: Bake to Perfection
Place the dish in the preheated oven and bake for 35-40 minutes. You’ll know the cake is done when the top is golden brown and a toothpick inserted in the center comes out with moist crumbs, not wet batter. This ensures that the Peanut Butter Cup Dump Cake has a crisp exterior and a gooey interior.
Step 7: Cool Before Serving
Once baked, remove the cake from the oven and let it cool for at least 15 minutes. This cooling step allows the flavors to set and makes it easier to serve. If you want to enhance the indulgence, consider serving it warm with a scoop of ice cream for a truly delightful treat.

Peanut Butter Cup Dump Cake Recipe FAQs
What type of peanut butter is best for this recipe?
I recommend using creamy peanut butter for a smooth, rich layer in your Peanut Butter Cup Dump Cake. Crunchy peanut butter can also be used for added texture, but it might affect the cake’s consistency slightly. If you or someone you know has nut allergies, sunflower seed butter is a great alternative that can offer a similar creaminess.
How should I store leftovers of the Peanut Butter Cup Dump Cake?
Store your Peanut Butter Cup Dump Cake in an airtight container at room temperature for up to 2 days. If you want it to last longer, refrigerate it for up to 5 days. Make sure to cover it well—this keeps it moist and delicious while preventing it from drying out!
Can I freeze Peanut Butter Cup Dump Cake?
Absolutely! To freeze your Peanut Butter Cup Dump Cake, wrap individual portions tightly in plastic wrap and then in foil. This simple step ensures they stay fresh and delicious. You can freeze it for up to 1 month. When you’re ready to enjoy a slice, just thaw it in the refrigerator overnight and reheat in the microwave for 20-30 seconds to get that delightful warm texture back!
What if my cake sinks in the middle after baking?
If your Peanut Butter Cup Dump Cake sinks in the middle, there may have been too much liquid added to the cake mix or it wasn’t baked long enough. To prevent this, ensure you are distributing the melted butter and milk evenly over the cake mix without stirring. Additionally, always test the cake with a toothpick—look for moist crumbs, which means it’s ready, rather than a wet batter.
Can this recipe be adapted for different dietary needs?
Yes, you can absolutely adapt the Peanut Butter Cup Dump Cake for different dietary preferences! For a gluten-free version, swap the boxed chocolate cake mix for a gluten-free alternative. If you’re looking for a lower sugar option, consider using a sugar substitute that works for baking. Also, please note that mini peanut butter cups may contain gluten or nuts, so always check labels for allergens if you’re serving guests with dietary restrictions.
How do I enhance the flavor of my dump cake?
For an extra flavor boost, consider adding a teaspoon of instant espresso powder to the cake mix before layering. This enhances the chocolate flavor beautifully! You could also experiment with swirling in caramel instead of chocolate chips for a delightful twist. Whatever you choose, the key is to have fun and make this cake your own!
