One day, I needed a peanut butter fix. I mixed a box of chocolate cake mix, some butter, and a whole bag of mini peanut butter cups. The smell in my kitchen was amazing!

Peanut Butter Cup Dump Cake
Ingredients
Equipment
Method
First, let’s lay everything out. A quick way to figure it out is by preheating your oven to 350*F and following the lens section instructions. Grab a 9×13 inch baking dish. You don’t usually need to grease it, but you can if you’d like.
Now, lets add the rich base.In a medium bowl, combine 1 cup of creamy peanut butter, 1/2 cup of melted unsalted butter, 1/2 cup of whole milk, 1 teaspoon vanilla extract and 1 cup granulated sugar. Whisk it until smooth and it looks like thick, shiny pudding. This combination is what gives the cake its gooey, fudgy base.Combine and pour this base mixture into your prepared pan cautiously. Spread it out across the bottom using your spatula or spoon. If it’s a little sticky, all the better; you just want to cover that base!
Next up, dry ingredients go in! 2) Take the whole box of chocolate fudge cake mix and sprinkle over the peanut butter layer. This is really important: don’t touch it or stir it! Just be sure that it’s an even spread of chocolate powder.
Now for the star attraction. How to Make Mini Peanut Butter Cup Cookies: Open the Ziploc bag with unwrapped mini pb cups. Spread them generously on top of the chocolate cake mix layer.You don’t want them to be anywhere! Finally pour the other half of the melted butter over top, as evenly as you can. This fat will seep down into the dry mix as it cooks, in so doing becoming a crisp and buttery topping.
Finally, carefully transfer the baking dish to your hot oven. Bake 45 to 55 minutes or until set. The precise timing will vary depending on your oven, so watch it.The cake is ready when the top is golden brown and you can see the peanut butter and chocolate mixture bubbling along the edges. Remove the cake when time is up and the top is golden.
Here’s the worst of it: You have to wait! I know you want to dive in immediately, but let it cool for at least 15 to 20 minutes on a rack.
This brief rest gives the molten peanut butter center a chance to set ever so slightly, which makes it easier to scoop out and serve without making a mess. Believe me, it is worth the wait!The only thing I recommend on top is a big scoop of vanilla ice cream, especially when it’s hot — the combination is heavenly.

Pro-Tips and Smart Ideas: The Notes Categories
But fear of a disappointing PBCD-cake Monday morning is what led me to these tips for ensuring your Peanut Butter Cup Dump Cake will be perfect each and every time you make it! These are my hacks from my kitchen!
Tips for Making it Easy
A way to make things easy is to melt all the butter at once. Cut one for base and one for drizzle on top.
If you would like to keep it simple, have all ingredients measured out before getting started. I tend to unwrap the peanut butter cups while the oven preheats.
Here’s also what you don’t have to sweat: getting a gooey, stiffly mixed cake mix laid out perfectly flat; some texture on top is exactly what you want when it comes time for that crispy crust.
A Family-Friendly Dessert Option
It is also very family friendly since the flavors are irresistible. You can even get the kids in on it! Ask them to remove the wrappers from the peanut butter cups, or to sprinkle on the dry cake mix.
It’s a joyous recipe to make with kids, an opportunity for the very young make and shape their own dough into balls (each should weigh about one ounce), have “snowball” fights by throwing them into pots of boiling salted water and taste as they go. Just remember to let it cool off a bit before letting little hands dive in!
Common Mistakes to Avoid
When You Mix the Cake: The only error would be “whisking” the dry cake mix layer. Don’t stir it! The stirring will destroy the classic action of this Dump Cake with the gooey base layer (bottom) and slightly crunchier top crust.
Cold Butter – Make sure both rounds of butter are completely melted. Cold butter won’t drizzle or mix properly, leading to uneven baking and dry spots on the surface.
Baking Time: Not too soon. The center may seem a little jiggly, but you’re looking for a fully set cheesecake before removing it. You’ll see bubbling edges and a deep gold top.
How to Store & Reheat Leftovers
But if you do happen to have any left over, this cake is freezable! (If you want to keep it longer, refrigerate for as long as 5 days.)
To reheat, scoop a serving onto a plate and microwave for 20-30 seconds or so, or return the entire dish to a 300° F oven and let it warm through for about 10 minutes.
Variations for Making It Your Own
Sprinkling a small pinch of sea salt over the top before baking will add to the salty-sweet balance between the peanut butter and chocolate.
How to Make This Recipe Healthier
Though this dessert is indulgent, there are some ways to lighten it up a bit:
Go Light on the Milk: Substitute skim milk or almond milk for whole milk in the peanut butter base.
Healthier Peanut Butter: Opt for a natural peanut butter with lower added sugars, but try to go creamy for the consistency.
Cut Sugar: You can reduce the added granulated sugar in the base mixture to 3/4 cup with little impact on flavor.
Fun Variations to Try
Caramel Twist: When spreading the mix sprinkle most of your dry mixture, then drizzle about 1/2 cup of caramel sauce over the peanut butter layer and finish with remaining dry top.
White Chocolate: Use a white cake mix and add in white chocolate chips rather than chocolate, while still going with a peanut butter base.
Best Matches for Serving
This is a really rich cake, so it needs a good side to help balance the flavor!
The Classic Pairing A big scoop of vanilla bean ice cream is a must. The creamy, light ice cream melts perfectly into the warm cake.
Non-Dairy Lightener: A dollop of sweetened whipped cream.
Drink: Ice-cold whole milk in a plain glass to balance the richness of the pastry.
