Crock Pot Peanut Butter Cup Cake


So this cake happened today.
Like realllly happened.

I started it.
I went to the pool and watched my kids do 40 million cannonballs.
I came home.
And waiting for me was a cake.
In a crock pot.


This is, in fact, real life.
And there are peanut butter cups involved.

Because I love you.
And after you eat this cake you will love me too.

Crock Pot Peanut Butter Cup Cake.
Did you hear me? IN A CROCK POT!

I’m caking like it’s 1983.

Just mix up your ingredients.
And since we’re in the 80’s, let’s start with a cake mix.
Photobucket Then put it in your crock.
What a crock it is.
Photobucket And wait a bunch of hours.
I suggest you get on with your life during this time.
Watching the crock pot work is a losing battle, folks.

After the longest 6 1/2 hours of our life you should eat.
With ice cream.
Good gosh almighty.

Crock Pot Peanut Butter Cup Cake
  • 1 (18.25 oz) pkg chocolate cake mix
  • 1½ cups sour cream
  • ½ cup peanut butter
  • 1 (3 or 4 oz) pkg of instant chocolate pudding mix any size will be fine
  • 1 cup mini peanut butter cups, or 1 cup chopped peanut butter cups
  • ¾ cup vegetable oil
  • 4 eggs
  • 1 cup water
  1. Spray crock pot with non stick spray. I used my 8 qt crock pot.
  2. Mix all ingredients together and pour in crock.
  3. Cover and cook on low for 6½-7 hours until center is set.
  4. Serve warm with ice cream.
Cook times may vary slightly based on your crock pot...low on some might be higher than on others.
Also, the cake is very loose, more like a pudding-cake.

I thought you were my heroine before…but oh no. It’s now. AMAZING.

I’ve seen a couple different crock pot dessert recipes in the past day….all of a sudden, slow cookers in the summer. Hey, whatever it takes to make a fab dessert.

This looks so gooey and amazing…and wonderful!

June 20, 2012 7:32 pm

Brilliant that you don’t have to heat up the house on a hottttt day. YUM!

O.M.G. this looks amazing! I will be trying this!

June 20, 2012 7:49 pm

Yuuuuuum! The crock pot cake idea is genius anyway but peanut butter chocolate is way better than the yellow cake/strawberry pie filling one I’ve been making!

June 20, 2012 7:54 pm

This so sounds too good to be true! I can’t wait to try it!

Beat the heat and cook in a crock pot! I love coming home to food ready to eat in the crock pot and this would be the best thing to find in the crock pot!

June 20, 2012 8:45 pm

I could not have dashed over any quicker from Pinterest!!! This is amazing with all that chocolate sauce. Smart in the crock pot!

Evil, I tell you. Brilliant, too.

I have never made dessert in my crockpot, but I am excited to give it a try! My crockpot is my favorite tool year round!

June 20, 2012 10:17 pm

This looks amazballs! I also love that you have a Ziplist feature right on your site. I plan to make this over the 4th of July for our family reunion (mostly because I am afraid I will eat the entire cake if there are no witnesses).

June 20, 2012 11:00 pm

If I did not already have some goodies to bring to my Bible Study this Friday I would so be bringing this! I’m looking forward to making it! My two favorite things- chocolate and peanut butter………..and it’s not going to heat the house! YAH!

June 21, 2012 7:46 am

I love cooking in my crockpot, especially the way it makes the house smell so “homey.” I can’t even imagine how good this must smell…for 6 1/2 hours!!!

June 21, 2012 7:51 am

The only word for this is WOW

June 21, 2012 7:59 am

oh no you didn’t.


see it’s stuff like this that makes me happy I have a crock pot, even if it sits in the basement, I so can bring it up to the kitchen. Yummy!

June 21, 2012 9:55 am

Oh please yes! I want to be small enough to swim in that.

June 21, 2012 10:30 am

June 21, 2012 12:06 pm

Amazing!! I have to get out my crockpot for this one!

June 21, 2012 12:50 pm

Slow cookers in the summer IS brilliant cause it doesn’t heat the oven! I LOVE IT!

June 21, 2012 2:34 pm

Okay…. this is the GREATEST! I can’t even begin to imagine what my Friday night will be like tomorrow. Of course, I’m trying to figure out if I can just put it in the crock pot when I get home tonight. Hmm….

June 21, 2012 2:41 pm

The best use of a crock pot EVAH!!!!!

June 21, 2012 2:54 pm

I was telling my boys we can’t make dessert because it’s too hot to use the oven. You have made me a big, stinkin’ liar!
(Good thing I’ve got a couple crock pots — DINNAH IS SERVED!)

June 21, 2012 3:15 pm

Holy smokes, this looks fantastic!! Now, I need a crock pot.

June 21, 2012 3:16 pm

It’s always nice to have a yummy dessert and not have to have the oven on during summer! Love it!

June 21, 2012 3:27 pm

So last week I had to bring my blender to work with me because I’m totally addicted to smoothies. This week, I’m totally bringing my crockpot in and we’re having cake at work!! I can’t wait to try this!!

Year ago when I bought my crock, I bought all the gadgets that went with it and the right cookbook. Bread, cakes (a special pan) and the roasting rack. Ive been using it and updating my recipes ever since.
One of the best investments I ever made…and still going after 35 years. Cool huh?
Thanks for a great (my fave flavours) recipe. I’ll be trying this one soon.

June 21, 2012 4:01 pm

O.M.G. This might just be the best thing that ever happened….
