Ingredients You’ll Need
Alright, let’s gather up all the goodies you’ll need to make this Peanut Butter Cup Dump Cake! Trust me, you won’t need to go on a wild scavenger hunt—most of these ingredients are probably already in your pantry!
- 1 box chocolate cake mix: This is the base of our cake, bringing that rich, chocolatey flavor. I usually go for a classic brand; they just make it so easy!
- 1 (3.9 oz) box instant chocolate pudding mix: This adds extra moisture and a dreamy texture. Don’t skip it—it’s a game changer!
- 2 cups whole milk: This is crucial for keeping the cake nice and moist. You can swap it for a non-dairy milk if you’d like, but I find whole milk gives the best results.
- 1/2 cup creamy peanut butter: Oh yes, the star of the show! Go for a creamy variety for that smooth texture. You can also use crunchy if you want a little extra bite!
- 1/2 cup butter, melted: This helps bind everything together and adds richness. I like using unsalted butter, so I can control the saltiness.
- 1 cup mini peanut butter cups, chopped: These little gems add bursts of peanut butter goodness throughout your cake. Feel free to chop them up a bit more if you want more chocolatey pieces!
- 1 cup milk chocolate chips: Because why not add more chocolate? They’re perfect for that melty, gooey texture!
- 1/2 cup chopped peanuts (optional): If you want to add a crunchy element, go for it! I love a good crunch, but it’s totally optional.
- Whipped cream or vanilla ice cream (for serving): This is how we take it over the top! Trust me, a dollop of whipped cream or a scoop of ice cream makes this cake sing!
There you have it! Gather these ingredients, and you’ll be well on your way to creating a dessert that’ll have everyone begging for the recipe!
Step-by-Step Instructions
Preparing the Batter
Okay, let’s get that batter ready! First things first, preheat your oven to 350°F (175°C). This will ensure your cake starts baking evenly, so don’t skip this step! While that’s heating up, grab a large mixing bowl and combine the chocolate cake mix and the instant chocolate pudding mix. Just dump them in together—easy peasy!
Next, it’s time to add the wet ingredients. Pour in those 2 cups of whole milk, followed by the creamy peanut butter and melted butter. Now, grab a whisk or an electric mixer and mix everything together until it’s smooth and lovely. You want to make sure there are no lumps—trust me, a smooth batter makes a happy cake! And don’t worry if it seems a little thick; that’s totally normal.
Once you’ve got a beautiful batter, gently fold in the chopped mini peanut butter cups and milk chocolate chips. This is where the magic happens! You’ll get those delicious pockets of peanut butter and chocolate in every bite. Just be careful not to overmix; we want to keep those chunks intact!
Baking the Cake
Now it’s time to bring this cake to life! Pour the batter into a greased baking dish—about 9×13 inches works perfectly. Spread it out evenly with a spatula. If you’re feeling adventurous and opted for the chopped peanuts, sprinkle them on top now for that extra crunch!
Pop the dish into your preheated oven and let it bake for 30-35 minutes. The smell will be heavenly, and you’ll want to keep checking for doneness. Just insert a toothpick into the center, and if it comes out clean or with just a few moist crumbs, you’re golden! Once it’s done, let it cool for about 10-15 minutes before serving. This will help the cake set up a bit more and make it easier to cut. Get ready for some seriously delicious dessert goodness!

Variations
Now, let’s have a little fun with this Peanut Butter Cup Dump Cake! One of the best things about this recipe is how easily it adapts to your taste. For instance, you can swap out the chocolate cake mix for a devil’s food cake mix for an even richer chocolate flavor. Or, if you’re feeling adventurous, try a yellow cake mix for a lighter twist that still pairs beautifully with peanut butter!
Feeling like a flavor adventure? Toss in some crushed Oreos instead of chopped peanuts for an extra chocolatey crunch. You could also mix in some caramel sauce or even a swirl of Nutella for that ultimate indulgence! The possibilities are endless, and adding seasonal ingredients like pumpkin spice in the fall can make it festive, too. Just remember to keep it fun and delicious—you can’t go wrong!
Serving and Storage Tips
When it comes to serving this Peanut Butter Cup Dump Cake, the options are endless! You can enjoy it warm right out of the oven with a generous scoop of vanilla ice cream melting on top—it’s pure bliss! If you prefer it chilled, just let it cool completely, and then serve it with a dollop of whipped cream. Either way, trust me, your friends and family will be raving about it!
Now, about storage: If you happen to have leftovers (which is rare, but it happens!), simply cover the cake with plastic wrap or transfer it to an airtight container. It’ll keep in the fridge for about 3-4 days. You can also freeze it for up to 2 months—just make sure to wrap it tightly! When you’re ready to enjoy it again, let it thaw in the fridge overnight and then pop it in the microwave for a quick warm-up. It’s just as delicious the second time around!
Helpful Notes
Before you dive into making this Peanut Butter Cup Dump Cake, here are a few handy tips to ensure your baking experience goes smoothly! First off, if you’re looking to make it a bit lighter, you can substitute the whole milk with a low-fat or non-dairy milk—just keep in mind that it might change the texture slightly. For more baking tips, check out our baking resources.
Also, ovens can vary, so keep an eye on your cake as it bakes! If your oven tends to run hot, check it a few minutes early to avoid overbaking. You want that perfect gooey center! And if you find the cake is a little too rich for your taste, serving it with fresh fruit like strawberries or raspberries can add a refreshing touch.

Lastly, don’t hesitate to experiment with different nut butters! Almond or cashew butter can give a unique twist while still keeping that delicious creamy texture. Happy baking, my friends!
