Slow Cooker Peanut Butter Chocolate Cake is a dessert that you will want to make over and over.
Hello! Today I have a new dessert recipe for you. This one is very rich and decadent, so if you are hoping for a light dessert, look away. My first thought when I bought the items for this recipe was to do a poke cake with peanut butter cool whip frosting. Instead, I went with a sweetened melted peanut butter topping.
How to make Slow Cooker Chocolate Peanut Butter Cake:
- In a large bowl mix together a deviled food cake mix, eggs, melted butter, and water. Stir in a small bag of mini resee’s peanut butter cups.
- Spray an oval slow cooker with non-stick spray and pour the batter into it.
- Cover and cook on HIGH for 2 hours without opening the lid during the cooking time.
- When the cooking time is done combine melted peanut butter and powdered sugar. Pour this over the hot cake.
- Top with halved bite-sized peanut butter cups.
- Serve and enjoy!
The topping in this recipe tastes like the peanut butter topping at Baskin Robbins. Every time I eat that peanut butter topping I don’t care if I’m ever skinny again. LOL
How to serve:
- Scoop the warm cake into serving bowls.
- Top with ice-cream or whipped cream.

As I always tell my students, “Make sure and read the directions before starting.” Lol! I used my 4.5 quart slow cooker, and it burnt on sides and raw in the middle. Completely my fault. Recipe says 6 quart cooker. I’m going to try again when I get a bigger slow cooker.
Amazing. Would not have thought it to be so. You have to try it.
I must say this recipe intrigued me and my husband and I are not cake fans, but love peanut butter and chocolate. Decided to make this for Valentine’s Day. It was a better hit with us the day after and day after and day after! Seriously, yummy!! Thanks for the recipe. Will make again!
I checked cake after 1.5 hrs and it was already over done. All peanut butter cups sank to bottom and melted to the bottom. Corners were burnt. Cake very dry. Whole family was disappointed.
Your slow cooker must cook very hot! I’m sorry this happened.
If I’m in a hurry and need to make this in the oven ~
-what size dish?
-what temperature?
-how long?
Thank you so much!!
Same as the box says is what I would do 🙂
Mine isn’t done in the middle.
Used reeses pieces for topping. Kids loved it
Do you have to take it out of the crockpot immediately after 2 hrs or can it stay in and put the frosting on like the video does?
Let it cool on a wire rack if you can. Don’t want it to continue to cook.
Does it have to be an oval slow cooker? What happens if it’s round?
I’m unsure if it would set in the middle in a round slow cooker. I have not tried.
How long and what temp would you make this in an instapot?
Can you make this ahead of time? Like the night before?
This was our Christmas Day dessert! I showed this recipe to my teen daughter and she proudly made it all by herself. Watching your video gave her great confidence and she was happy and delighted that we all gobbled it up. It was so yummy that we somehow found room to finish our bowls after a huge holiday meal – so good!! Thank you for this great recipe!
Ah! I’m so glad your daughter made it!
Is the cake suppose to be firm like a regularly baked cake or more soft in the center? Right now after 2 hours it is soft in the middle.
firm like a regular cake.
could this be doubled for a big crowd? also, would it work just as well using a gluten free cake mix? I have a friend in my bunco group with celiac…
I wouldn’t double it, it wouldn’t set in the middle. I’m unsure about gluten free, I have not tried. Sorry I’m not much help.
Could you substitute brownie mix for the cake mix?
I think it would work fine, follow the directions for liquids on the box.
Thank you!
Susanne, I would make the recipe in the oven for your celiac friend. I bet it would be yummy! My husband has Celiac Disease and everything here is gf except the mix.
So, if I made this ahead and just put the crook on warm would it work? Or should I keep the topping off, warm the cake and then add the topping?
It may be hard to reheat with out burning the edges. I would keep it room temperature and add the topping soon before serving.
These look easy an healthy
Healthy? Really?
Yum Yum Yum!!!! I am really the only fan of Peanut butter in this house and it is rather a lot of cake, in your experience, any other ideas to use instead of Reeses?
I have not made this recipe yet but your question prompted me to think some kind of mint candy to replace the Reese’s. Chocolate & mint are usually good together. York peppermint paddies?
If I were going to replace the Reeses with something mint, I would go with Andes mints instead of York Peppermint Patties….just my opinion!
I would use Andes baking mint chips!
What about rollo chocolate filled with caramel
What about m&m’s as an alternative?
I think that would be great!
