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. Cocoa powder: Look for the unsweetened baking cocoa powder, not the mix for making hot chocolate. Both natural and Dutch-process cocoa powder will work in this recipe.
  2. Yield: This recipe makes 1 gooey, delicious Chocolate Lava Cake, enough for 8 generous servings (see Tips and Variations for double and half recipe information).
  3. Storage: Store leftovers covered at room temperature for 2 to 3 days.
