Ingredients

Scale
  • 1 cup (125g) all-purpose flour (or gluten-free all-purpose blend)
  • 1/2 cup (100g) granulated sugar
  • 2 tablespoons (15g) unsweetened cocoa powder (Dutch-processed preferred)
  • 2 teaspoons baking powder
  • 1/4 teaspoon salt
  • 1/2 cup (120ml) whole milk (or dairy-free milk)
  • 1/3 cup (75g) unsalted butter, melted (or coconut oil for dairy-free)
  • 1 teaspoon vanilla extract
  • 1/2 cup (90g) semi-sweet chocolate chips (or dark chocolate chips)
  • 1/4 cup (25g) unsweetened cocoa powder
  • 3/4 cup (150g) packed light brown sugar
  • 1 1/2 cups (355ml) boiling water
  • Optional: Chopped toasted pecans or walnuts, pinch of espresso powder, orange zest

Instructions

  1. Spray the inside of a 4-6 quart slow cooker with nonstick spray or lightly grease with butter. Optionally, line the bottom with a circle of parchment paper.
  2. In a medium bowl, whisk together flour, granulated sugar, 2 tablespoons cocoa powder, baking powder, and salt. Sift if needed to remove cocoa lumps.
  3. Add milk, melted butter, and vanilla extract to the dry ingredients. Stir gently until just combined; do not overmix.
  4. Spread the batter evenly in the prepared crockpot.
  5. Sprinkle chocolate chips evenly over the batter.
  6. In a small bowl, mix 1/4 cup cocoa powder and brown sugar. Sprinkle this mixture over the batter and chocolate chips in the crockpot. Do not stir.
  7. Carefully pour boiling water over the top, covering the entire surface. Do not stir.
  8. Cover and cook on HIGH for 2 to 2 1/2 hours. Start checking at 2 hours; the cake should look set on top but jiggle slightly. If needed, cook an additional 15-30 minutes.
  9. Turn off the slow cooker and let the cake stand, uncovered, for about 20 minutes to set the top while keeping the bottom molten.
  10. Scoop into bowls, making sure to get both cake and lava. Serve warm with ice cream, whipped cream, or berries if desired.

Notes

Do not overmix the batter to keep the cake fluffy. Every slow cooker heats differently, so check for doneness at 2 hours. Resist lifting the lid during cooking to maintain steam and the lava texture. For gluten-free or dairy-free versions, substitute flour and milk as needed. Leftovers can be refrigerated for up to 3 days or frozen for up to 2 months. Serve warm for the best gooey texture.
