To make the cake batter:

  • Coat a slow cooker with nonstick spray. In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, and salt. In a second bowl, whisk together the milk, melted butter, and vanilla.
  • Make a well in the middle of the dry ingredients. Pour the wet ingredient in to the well and whisk until smooth. Pour into the bottom of a slow cooker.

To make the topping:

  • Whisk together the sugar, brown sugar, cocoa powder until evenly combined. Sprinkle evenly over the batter in the slow cooker.
  • Pour the hot water over the top of the batter and topping. Do not stir. Cover and cook on HIGH for 3 to 4 hours or LOW for 5 hours, or until a toothpick inserted in to the middle of the cake comes out clean with a few crumbs attached (see recipe notes).
  • Serve with ice cream or whipped cream, spooning the chocolate sauce from the bottom of the slow cooker over the top. Garnish with maraschino cherries if desired.



  1. Depending on the strength of your slow cooker, the cake will be done in about 3 to 4 hours on HIGH or in about 5 hours on LOW.
  2. If your crockpot switches to "warm" after it's done cooking, you can leave it in the crockpot on the "warm" setting for at least 2-3 hours without changing the cake. For example, I cooked the cake on LOW for 5 hours, then left it in the crockpot for 2 more hours on the "warm" setting, and it was still perfect.
  3. To make a half recipe, halve all of the ingredients and prepare in a 2-quart slow cooker. The cake will be done in about 2 hours on HIGH. Scroll up in the post to find exact ingredients cut in half.
  4. To double the recipe, double all ingredients and prepare in a 6-quart slow cooker. The cake will be done in 3 to 5 hours on HIGH or 4 to 6 hours on LOW.
