Make a decadent Slow Cooker Reese’s Peanut Butter Cake for your family. It has warm chocolate cake and melty peanut butter frosting and is topped with Reese’s peanut butter cups.

If you love warm dessert cuisine, skip using the cake pan and the oven for your crockpot. It is the perfect way to go. We also make Slow Cooker Blackberry Cobbler and Slow Cooker Lave Cake.

Can I make cake in a crockpot?

• You can make cake in the crockpot! It’s a perfect environment to create a warm cake you spoon out instead of slicing. Be sure to watch the timing for a crockpot cake can burn easily.
• This moist chocolate cake cooked in the slow cooker is perfect for family get-togethers, BBQs, birthday parties, or even a church potluck.

Ingredients

• Devil’s food cake mix – You can use any chocolate cake mix you like. We also use chocolate cake in our slow cooker s’mores cake recipe.
• 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 Reese 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 – Add the peanut butter to a small pan set over medium heat on the stove top.

Step Five – Stir until melted and smooth and then add the powdered sugar, whisking until smooth.

Step Six – Pour the sweetened creamy peanut butter frosting over the warm cake. 

Step Seven – 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 whip cream. (Try this Reeses Peanut Butter Cup Ice Cream recipe) You can also provide chopped peanut butter cups, chocolate chips (semi-sweet chocolate chips are great), and/or diced fruit for an extra topping choice.
• Have a bottle of chocolate syrup ready for garnish if desired.
• This is a great dessert to let your guests serve themselves; they can choose how much dessert and toppings they prefer.

Variations

• 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.
