Peanut Butter Cup Cake Crock Pot Recipe
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.
Yezzzzz.
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.
How to Make This Crock Pot Cake Mix Dessert:


Just mix up your ingredients.
And since we’re in the 80’s, let’s start with a cake mix.
Then put it in your crock.
What a crock it is.
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.
