Ingredients for Peanut Butter Cup Dump Cake
Creating the perfect Peanut Butter Cup Dump Cake starts with gathering the right ingredients.
Here’s what you’ll need:
- Chocolate cake mix: The base of this dessert, providing a rich chocolate flavor. You can use any brand you prefer.
- Creamy peanut butter: This adds that irresistible nutty flavor and creamy texture. Go for the classic creamy variety for the best results.
- Milk: It helps to moisten the batter, making it soft and fluffy. Whole milk works best, but any milk will do.
- Semi-sweet chocolate chips: These little morsels melt beautifully, adding pockets of chocolatey goodness throughout the cake.
- Mini peanut butter cups: Chopped up, they provide delightful bursts of flavor and texture. You can find these in most grocery stores.
- Unsalted butter: Melted, it enriches the batter and helps everything come together smoothly.
- Vanilla extract: A splash of this adds depth to the flavor, enhancing the overall taste of the cake.
- Powdered sugar (optional): For a sweet finishing touch, dusting the cake with powdered sugar before serving is a nice touch.
For those looking to mix things up, consider substituting the chocolate cake mix with a yellow cake mix for a different flavor profile.

How to Make Peanut Butter Cup Dump Cake
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C).
While it warms up, grab a 9×13-inch baking dish and grease it with non-stick spray or a bit of butter.
This step is crucial; it ensures your cake won’t stick and makes for easy cleanup later.
Trust me, you’ll thank yourself when it’s time to serve this delicious dessert!
Step 2: Mix the Batter
In a large mixing bowl, combine the chocolate cake mix, creamy peanut butter, milk, melted butter, and vanilla extract.
Use a spatula or whisk to mix everything together until just combined.
Be careful not to overmix; a few lumps are perfectly fine.
This batter is the heart of your Peanut Butter Cup Dump Cake, so make sure it’s well-blended but not overworked!
Step 3: Pour and Spread
Once your batter is ready, pour it into the prepared baking dish.
Use a spatula to spread it evenly across the bottom.
This ensures that every bite of your cake has that rich chocolate flavor.
Don’t worry if it looks a bit rustic; it’s all part of the charm of a dump cake!
Step 4: Add Toppings
Now comes the fun part!
Sprinkle the semi-sweet chocolate chips and chopped mini peanut butter cups evenly over the batter.
This is where the magic happens, as these toppings will melt and create gooey pockets of deliciousness.
Feel free to be generous; after all, who doesn’t love extra chocolate and peanut butter?
Step 5: Bake
Place your baking dish in the preheated oven and let it bake for 30-35 minutes.
Keep an eye on it; you’ll know it’s done when the cake is set and a toothpick inserted in the center comes out clean.
The aroma wafting through your kitchen will be irresistible, so be prepared for some eager taste testers!
Step 6: Cool and Serve
Once baked, remove the cake from the oven and let it cool for about 10 minutes.
This cooling time allows the flavors to settle and makes it easier to cut.
If you want to add a touch of sweetness, dust the top with powdered sugar before serving.
Now, slice it up and enjoy the delightful layers of chocolate and peanut butter!
