  • Preheat oven to 350F°/180°C. Grease 2 ramekins with butter and set aside.
  • In a bowl combine the dry ingredients: cocoa powder, sweetener, baking powder.
  • In a separate bowl beat well the eggs with a fork. Add the heavy whipping cream, vanilla extract and mix again.
  • Add the egg mixture to the dry ingredients and combine together until you get a pourable consistency.
  • Bake for 12 minutes or until the top is set but still moist.
  • Turn out onto plates and serve hot!



  1. Make sure you are using high-quality unsweetened cocoa powder.
  2. If you want to serve your lava cake on a plate, make sure you are greasing very well the ramekins.
  3. Try not to overbake the lava cake, to get the gooey pudding texture.
