Make a decadent Slow Cooker Peanut Butter Cake for your family. It has warm chocolate cake, melty peanut butter frosting, and topped with Reese’s peanut butter cups.
If you love a warm dessert, using your crockpot is the way to go. We also make blackberry cobbler and lava cake in our crockpot!
Can I make cake in a crockpot?
- You can make cake in the crockpot! It’s a perfect environment to make a warm cake that you spoon out instead of slicing. Be sure to watch the timing for a crockpot cake can burn easily.
- Warm cake in the slow cooker is perfect for family get-togethers, BBQ’s, birthday party or even a church potluck.
Ingredients
- Devil’s food cake mix – Can use any chocolate cake mix you like.
- Wet ingredients for cake – Eggs, melted butter (I use melted butter instead of oil) and water
- Warm glaze – Melted peanut butter and powdered sugar make the best topping for this chocolate cake.
- Reese’s Peanut Butter Cups – Mini peanut butter cups go inside the batter and halved bite size Reese’s go on top for garnish.
Step-by-Step Directions
Step One – Mix a deviled food cake mix, eggs, melted butter, and water in a large bowl. Stir in a small bag of mini resee’s peanut butter cups.
Step Two – Spray an oval slow cooker with non-stick spray and pour the batter into it.
Step Three – Cook on HIGH for 2 hours without opening the lid during the cooking time.
Step Four – Combine melted peanut butter and powdered sugar when the cooking time is done. Pour this over the hot cake layer.
Step Five – Top with halved bite-sized peanut butter cups. Serve and enjoy!
How to serve warm cake
- Scoop the warm cake into serving bowls.
- Top with ice-cream or whipped cream.
- Have a bottle of chocolate syrup ready for garnish if desired.
- This is a great dessert to let you guests serve themselves, they can choose how much dessert and toppings they prefer.
Recipe FAQs and Variations
Yes! You can make Reese’s Peanut Butter Cake in the oven. Bake in a 9×13 pan, and bake as directed on the cake mix box.
Coffee – Use freshly brewed coffee in place of the water; it will have a slight hint of coffee and add depth of flavor to the cake.
White Cake Mix – Not a huge chocolate fan? Use a white cake mix instead of chocolate, and you will have wonderful vanilla and peanut butter dessert.
Reese’s Pieces – Use Reese’s pieces instead of cups for a fun twist! Or you can add a handful of both for some added texture.
The topping in this recipe tastes like the peanut butter topping at Baskin Robbins. It’s not overly sweet and goes great with chocolate and ice cream.
If desired, you can let the cake cool on the counter and place the entire slow cooker insert in the fridge. Flip the lid over to make it fit better in the refrigerator. Or spoon into airtight containers (this can be messy).
Freeze the leftover peanut butter cake in airtight containers for up three months. Thaw, warm, and enjoy!
Warm single servings in the microwave for about 30 seconds.

This is the most delicious chocolate cake with the peanut butter icing! You won’t be disappointed! ❤️❤️❤️
OMG this looks simply delish.
I have tried this twice and it burns before it gets done. I have a new crock pot, and it works great with other stuff. Any suggestions?
It may cook a touch too hot for cakes. Are you leaving the lid on?
I like to make one pot things. Im old and buy myself It would be nice to see easet stuf to make for one with left overs.
Can this be made in a 9 x 13 crockpot?
I’m sure you can Kim. May not take as long for it will make it thinner.
Hi will this work in a round crock pot, or will that be too small?
It may be too small. You could cut it in half.
Easy and delicious ,
What’s the best way to store what is left?
If you have room in the fridge you can put the entire slow cooker insert and lid in there. Or spoon into a large storage container.
Not bad
Hello. Can I use a chocolate cake mix instead of devils cake? I havent been able to find a devils cake mix
.
Yes! that will work just as well.
Can you still make this as a poke cake? When making a poke cake do you wait for cake and the Pb frosting to cool before pouring it over? I’m actually baking the cake in the oven for my son’s bday. Curious as whether to poke or not.
did you end up making this as a poke cake? I wanted to do the same but was unsure of whether to follow the directions on the box, or the directions here. Did the filling and the cake have to cool first?
I’m wondering about doing a poke cake too. Any tips??
How would you convert the baking time for a round crock pot? Any suggestions?
Hi Debbie! Just follow the 9×13 instructions on the box. It will work great.
I actually figured it out on my own. Instead of cooking on high for 2 hours I cooked on low for 2 1/2 hours. It came out perfect!!
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.
I had a 4 quart and had a similar thing not completely burned but overdone. I ground out the cake with a fork and mixed it all together. It looked like a batter half baked. I baked it in a 13×9 pan on 350 for 15 minutes, made the icing and it turned out fine!
Amazing. Would not have thought it to be so. You have to try it.
