Peanut Butter Cup Dump Cake – Just 4 ingredients come together to make a rich, fudgy, chocolate dump cake loaded with lots of peanut butter cups!
I like baking and coming up with new desserts. I know not everyone is like that, but it is something I definitely enjoy! Something like Mint Chocolate Chip Pie is easy to make, but always impresses everyone.
But sometimes you want to fall back on a classic, and maybe update it a little bit. A dump cake is a classic dessert that is so easy to make. Everyone loves them! This chocolate dump cake gets a little fun with the add in of peanut butter cups. But the same classic 3 ingredients, and the same super easy recipe.
What is a Dump Cake
It is a super simple dessert where you just mix the ingredients together and bake. It starts with a cake mix and then often times some kind of fruit filling and butter. Here we used a chocolate cake mix and a box of chocolate pudding with milk to bring it all together.
How to Make a Dump Cake
It is exactly what it sounds like, just dump the ingredients and bake. Lots of times you layer the ingredients in the baking dish and don’t even mix it. This one is a little different because I use milk to bring it all together. But you can dump everything in the baking dish and mix in there if you want.
- Mix together cake mix, pudding mix and milk until it is well blended.
- The mixture will be very thick, which is totally fine! Fold in all of the peanut butter cups.
- Spread into a 13 x 9 inch baking dish. And bake for about 25 minutes until a tester comes out clean.
- Let the cake cool before serving.
Have you ever tried a dump cake? The concept is super easy. Just dump cake mix, pudding mix, and milk together. Then you bake. No mixer required. Super easy when you have no time to bake something. You can use any flavor cake you want! It is dfferent than a chocolate sheet cake, but so good and you will love it!
This chocolate dump cake is perfect to then dress up how ever you want. Add in chocolate chips, cherry pie filling, candy of your choice. Top with whipped cream, ice cream, or even homemade hot fudge sauce. So easy to customize to whatever your family likes. Pumpkin Dump Cake is a great one to make in the fall.
So if you are craving chocolate and want something super easy, look no further than a dump cake! Seriously doesn’t get much easier or faster!

Emily @ Life on Food says
If I had to wait 90 minutes for a car thing I would most definitely need some chocolate to soothe the soul after. This cake looks super yum!!
Jessica @ A Kitchen Addiction says
Love easy cakes like this, especially when chocolate and peanut butter are involved!
Carol at Wild Goose Tea says
You can make a peanut butter dump cake—wow you did good. I had no idea.
Thank you!!!
Dawn says
Two questions: what flavor pudding, and what size? Other than that, it looks yummy, and I am going to try it.
Erin S says
Chocolate pudding, and whatever the standard size box is (I think it says 4 servings on the outside). Sorry, I am traveling, and do not have access to the size right now.
Bex says
So do you use all the packages of pudding in one box? Or are you just using one packet of it?
Erin S says
I package of chocolate pudding comes only one to the package. At least in the US. Gelatin has multiple to a package, but that is not what you are using. Where are you located?
Kelsey says
Made this tonight and it is in the oven now. A little rough when there is a pop up ad I was unable to shut down in order to read the directions, (Triseba) Perhaps this can be fixed for others. I was able to “Print” and bring up a word doc version, which helped. Anticipating how yummy it will be when done.
Sheena says
This looks awesome! However, it is most definitely NOT a dump cake! A dump cake is made by dumping all the ingredients in the baking pan in a particular order without having to mix anything ahead of time. The baking process causes everything to mix together and creates the final product. All you do is dump say butter, cake mix, fruit, and pie filling into a pan.
Jeff says
Made it today; more of a brownie and not technically a dump cake but easy and tasty. Took about 40 minutes at 350
Demeter says
It really doesn’t get any easier than this! Perfect for satisfying that peanut butter and chocolate craving. Looks fantastic!
Sara Welch says
Wow! So much ooey gooey chocolate goodness in one dessert! This looks restaurant worthy, indeed!
Beth Pierce says

Steph says
Love this recipe! It was the perfect blend of chocolate and peanut butter!
Lora says
After a long day this cake is all I need to make my weekend start off in the right way!!
Melanie Bauer says
Looks heavenly! I’m pretty sure everyone will go crazy for this, gotta try it soon!
Danielle Gregory says
This looks yum, and i’m definitely going to try it. However, this is NOT a dump cake. Dump cake is so named because the ingredients are just “dumped” into the pan, without mixing or using a separate bowl for anything.
Deb says
Can you put this cake mix into cupcake tins? At what temp and for how long?
Erin S says
I am sure you could. I have never tried it that way, so not sure on the time. I would start at 350 for 12 minutes and start checking to see when they are done.
Crystal Ryan says
is it really just 3/4 cup of milk the box of pudding calls for more and yours was so much more liquidy in the video than mine is and I haven’t even added the cake mix yet
Erin S says
The recipe calls for 1 3/4 cups of milk.
Crystal Ryan says
thank you so much it said 1 and I thought like 1 box you know lol thanks again can’t wait to spring this on my boys stay safe and keep it up
Erin S says
Hope you enjoy!
Juliane says

katerina @ diethood.com says
This is my kind of dessert! It looks and sounds incredibly delicious!
Beti | easyweeknightrecipes says
I love peanut butter! This cake is incredible!!
Sandra says
This is so hard to resist! Can’t wait to make it again!
Erik says
Such amazing flavor! This dessert is definitely gonna disappear fast.
Steph says
Does it have to be instant pudding mix? I have heat & serve on hand, so I was wondering….
Erin S says
I think heat & serve would work fine. The only real difference in them is the thickening agent and how it works – either heat or just let it set. Since you are cooking it, it shouldn’t make a difference.
Mary C. says
Does the dump cake need to be refrigerated after it cools?
Erin S says
Nope, room temperature is fine
