  • 1 cup (142 g) all-purpose flour
  • 2 tablespoons unsweetened cocoa powder
  • ½ cup (106 g) sugar
  • 1 ½ teaspoons baking powder
  • teaspoon salt
  • ½ cup milk
  • 2 tablespoons canola oil
  • 1 tablespoon vanilla extract
  • ½ cup (128 g) smooth or chunky peanut butter
  • ½ cup (85 g) semisweet chocolate chips


  • 3 tablespoons unsweetened cocoa powder
  • ¾ cup (159 g) sugar
  • 1 ½ cups boiling water
  • Vanilla ice cream for serving


  • Coat a medium round or oval slow cooker with nonstick cooking spray.
  • In a medium size bowl, whisk together the flour, cocoa, sugar, baking powder, and salt. Make a well in the center, add the milk, oil, and vanilla, and stir in widening circles, gradually incorporating the dry ingredients, until you have a smooth batter. Stir in the peanut butter. The batter will be thick. Stir in the chocolate chips. Spread evenly in the crockpot.
  • To make the topping, in another medium-size bowl, combine the cocoa, and sugar; pour in the boiling water and whisk until smooth. Gently pour over the batter in the cooker; DO NOT STIR. Cover and cook on HIGH until puffed and the top layer is set, 2 to 2 ½ hours.
  • Turn off the cooker and let it stand, covered for 30 minutes before serving.
  • Serve with vanilla ice cream.
