I Made This Peanut Butter Cup Dump Cake
“Peanut Butter Cup Dump Cake: My New Obsession!”
Heyyy, you ever just stare at a box of cake mix and think, “how can I make this even more ridiculously delicious?” 👀 Well, I did that last week, and OMG, I created this insane Peanut Butter Cup Dump Cake that’s basically a chocolate and peanut butter lover’s paradise! It’s gooey, rich, and, like, feels like a warm hug in dessert form.

Anyway… here’s the kicker. I was trying to impress my friends for game night (spoiler: I did), and I totally forgot I had to run to the store. So, I’m in the grocery aisle, realizing I have zero ingredients. Like, zero. But then I saw the cake mix staring at me, and it hit me. The dump cake is calling my name! 🎉
Okay, Let’s Talk Ingredients
So here’s what you need to grab at the store (and trust me, this is super easy):
– 1 box chocolate cake mix (the classic kind, you know?)
– 1 (3.9 oz) box instant chocolate pudding mix (this is the magic)
– 1/2 cup creamy peanut butter (smooth, please. Crunchy is a whole other vibe)
– 1 cup mini peanut butter cups, chopped (like, who doesn’t love those?)
I’m telling you, just looking at this combo makes me drool a little. 😋 Oh, and if you can find those mini cups with the Halloween wrappers—grab ’em! They add a fun touch, plus it’s like a little surprise when you bite in!
So Here’s Why I Make This Constantly
I can’t even explain how much this cake means to me. So my mom used to make a chocolate pudding cake for my birthday every year, and I’d get all excited about it. But then I found out that you can just dump everything in a pan, and it’s like a cake and brownie had a baby. Like, why haven’t I been making this my whole life?!
One time, I made it for my friend’s birthday, and I had my little niece help me. She was literally just throwing ingredients in, and we ended up with this epic mess everywhere! Flour on her cheeks, chocolate everywhere—but the cake? A-M-A-Z-I-N-G. We couldn’t stop eating it. Laughter, chaos, and a total sugar rush—all the best vibes!
The One Trick That Changes Everything
Okay, listen up! The key here is to mix the peanut butter with the pudding mix before adding it all together. Like, it creates this super creamy layer that just makes everything rich and gooey. I’ve tried just dumping everything separately, and it’s good, but this? Game-changer. Seriously.

Don’t Mess This Up (My Top Tips)
Alright, so here’s what I learned the hard way: DO NOT overbake the cake. I mean, I left it in for 30 minutes once (whoops) and it turned into a dry brick. Like, no one wants a sad, dry cake. So, set your timer for 25 minutes, but start checking at 22.
Also, don’t skip the mini peanut butter cups on top. They’re the cherry on the sundae, you know? Oh, and a scoop of vanilla ice cream on the side? Yesss, please!
How to Keep Them From Disappearing (Or, How to Store Them)
Okay, if you somehow have leftovers (which I don’t know how that’s possible), just cover it with aluminum foil or pop it in an airtight container and stick it in the fridge. It’ll last about 3-4 days, but trust me, it won’t last that long! I mean, how could it?
