Slow Cooker Peanut Butter Chocolate Swirl Cake



I am not really sure if I should call this cake or if I should call it quick bread. It can really play both parts, becoming a decadent dessert with a dollop of whipped cream, or a delicious breakfast with a smear of butter. Either way, it makes a wonderful summer treat. Using your slow cooker means enjoying delicious baked goods without heating up your kitchen!

Slow Cooker Peanut Butter Chocolate Swirl Cake


  • 2 cups almond flour
  • Sweetener equivalent to 3/4 cup sugar
  • 1/4 cup coconut flour OR 1/2 cup peanut flour
  • 1/4 cup unflavored whey protein powder
  • 1 tbsp baking powder
  • 1/4 tsp salt
  • 3/4 cup peanut butter, melted
  • 1/2 cup butter, melted
  • 4 large eggs
  • 1 tsp vanilla extract
  • 1/2 cup water
  • 2 ounces sugar-free dark chocolate, melted


  1. Grease the insert of a 6 quart slow cooker well.
  2. In a large bowl, whisk together the almond flour, coconut flour, whey protein, baking powder, and salt. Stir in melted peanut butter, melted butter, eggs, vanilla extract, and water until well combined.
  3. Spread about two thirds of the batter in slow cooker and dollop with half of the melted chocolate. Swirl with a knife. Dollop with remaining batter and chocolate and swirl again.
  4. Bake on low for 3 1/2 hours to 4 hours (it should be just slightly undercooked in the center).
  5. Turn slow cooker off and let cool, as it will continue to cook for a little bit from the remaining heat in the slow cooker.
  6. Cut into 12 pieces to serve.

I have never baked in my slow cooker, so do you leave the lid off or on?

Is there any options for those who does not have a slow cooker? Would be great to have that alternative too. Degrees and time in the oven and so on. Thanks.

I have vanilla flavored whey protein. Would that work if I omit or reduce the vanilla?

Cake in a slow cooker. I think I’ll try it…especially if there’s peanut butter and chocolate involved!

Why use whey protein?
