Ingredients
Before we dive in, let’s talk ingredients. I’m all for keeping it simple, and this recipe is no exception. I mean, I’ve definitely had those moments where I’m halfway through and—oops!—I’m out of a key ingredient. But here’s your list, so you can avoid my oh-so-frequent grocery mishaps.
- 1 box chocolate cake mix (any brand will do, but I’m partial to Betty Crocker)
- 1 cup creamy peanut butter (don’t skimp on this; go for the good stuff)
- 1 cup chocolate chips (I love using dark chocolate here for that rich flavor)
- 1/2 cup butter, melted (that’s one stick, folks)
- 1 cup milk (whole milk makes it extra decadent)
- 2 cups peanut butter cups, chopped (the more, the merrier, honestly)
- Optional: vanilla ice cream, for serving (because why not?)
Instructions
Let’s get down to business. This recipe is as easy as it gets, but don’t let that fool you into thinking it’s any less divine. Here’s what you need to do:
- Preheat your oven to 350°F. Don’t pull a ‘me’ and forget this step, or you’ll be sitting around with a bowl of ingredients and nowhere to go.
- Grab a 9×13 inch baking dish and give it a quick spray with non-stick cooking spray.
- In a large bowl, mix together the chocolate cake mix, melted butter, and milk until well combined. It’ll be thick, but that’s exactly what you want.
- Now, take that bowl of chocolatey goodness and spread it evenly in the bottom of your baking dish.
- Drop dollops of creamy peanut butter all over the top of the cake mix. Don’t be shy; those pockets of peanut butter are what we’re after.
- Sprinkle the chocolate chips all over, then top with the chopped peanut butter cups. It’ll look like a candy lover’s dream at this point.
- Bake for about 35 minutes. You’ll know it’s done when the edges start to pull away from the sides of the dish, and the center is set but still a bit wobbly.
- Let it cool for a bit before serving. If you’re going all out, plop a scoop of vanilla ice cream on top while it’s still warm.

Tips & Tricks
Alright, you’ve got the basics, but let’s talk shop for a second. Here are a few nuggets of wisdom to make sure your dump cake is the talk of the town (or at least your kitchen).
- Chocolate Overload: If you’re a chocoholic like me, go ahead and use chocolate milk instead of regular. It’s a game changer!
- Peanut Butter Quality: Honestly, the better the peanut butter, the better the cake. I learned this the hard way when I used a bargain brand and the flavor just wasn’t there.
- Mix-Ins: Want to mix it up? Try throwing in some crushed pretzels or a drizzle of caramel on top. Sweet and salty, baby!
But here’s the thing – baking is supposed to be fun, so don’t stress if things go a little sideways. I once forgot the cake was in the oven and ended up with a crispy top layer that my husband actually preferred. Go figure!
