Peanut Butter Chocolate Cake Slow Cooker Recipe

Bake this peanut butter, chocolate-y treat for the whole family right in your Crockpot™ slow cooker.

Prep Time
< 15 minutes
Cook Time
< 3 hours
  • 15 ¼ ounces devil’s food cake mix
  • 1 cup water
  • ½ cup salted butter, melted
  • 3 eggs
  • 8 ounce package mini Reese’s peanut butter cups
  • 1 cup creamy peanut butter
  • 3 tablespoons powdered sugar
  • 10 bite size Reese’s peanut butter cups
  1. In a large bowl mix together the cake mix, water, butter, and eggs until smooth. Some lumps are ok, that is normal. Stir in the mini peanut butter cups.
  2. Spray the Crockpot™ slow cooker with non stick spray. Add the batter to the slow cooker and spread out into an even layer. Cover and cook on HIGH for 2 hours without opening the lid during the cooking time.
  3. When the cooking time is done, remove the cake from the heat, to keep it from continuing to cook. In a small pan set over medium heat on the stove top, add the peanut butter. Stir until melted and smooth, watch closely because it will burn quickly. Add the powdered sugar and whisk until smooth.
  4. Pour over the sweetened peanut butter over the warm cake. Top with cut up Reese’s peanut butter cups.
  5. Serve and enjoy! Great with ice cream or whipped cream
