Servings6 servings


  • 1 cup flour
  • 2 tablespoons unsweetened cocoa + 3 tablespoons for frosting
  • ½ cup sugar + ½ cup for frosting
  • 1 ½ teaspoons baking powder
  • ½ teaspoon salt
  • ¼ cup Stout + ¾ cup for frosting
  • 1 egg
  • 4 tablespoons coconut oil
  • 1 tablespoon vanilla
  • ½ cup Nutella or peanut butter
  • ½ cup water


  • Whisk flour, 2 tablespoons of cocoa, ½ cup sugar, baking powder, and salt together.
  • Make a well in the center of the dry ingredients and add ¼ cup Stout, the oil, the egg, and the vanilla. Give it a quick whisk.
  • Gently stir the wet ingredients fully into the dry ingredients with a wooden spoon or spatula.
  • Add the Nutella or peanut butter and stir gently just until the large chunks are broken up. It will be very thick, don't worry.
  • Press the batter into a 4 quart slow-cooker (a larger slow-cooker will work as well) that has been well-sprayed with cooking spray.
  • In a small saucepan whisk up the remaining cocoa powder (3 tablespoons), sugar (½ cup), Stout (¾ cup), and water (½ cup). Let come to a gentle boil on med-high heat, stirring often. optional...try using the microwave. I usually start with 1 minute and add 20 second intervals. But be careful, this can burn quickly with this method!
  • Pour the liquid directly on top of the batter in the slow-cooker.
  • Turn the slow-cooker on low and let cook for 3 hours.


Serve this cake warm for the ultimate in gooey chocolate! The frosting will settle to the bottom of the slow-cooker, simply spoon it over your warm cake. And, of course, top with ice cream for the ultimate in a chocolate dessert!
To replace the Stout in the cake you can substitute 2% milk. To replace the Stout in the frosting you can remove it and change the water amount from ½ cup to 1 ½ cups.
