Calories 341 kcal


  • 1 Tablespoon Vegan margarine or butter
  • 2 Tablespoons Caster sugar
  • ½ Teaspoon Vanilla extract (or cold coffee)
  • 3 Tablespoons Self-raising flour
  • 1 Tablespoon Cocoa powder
  • 2+½ Tablespoons Plant-based milk (I used soy)
  • Small handful Vegan chocolate chips or chunks


  1. Mix the margarine and sugar together in a mug or ramekin. I recommend using one that's 3.5-inches wide to ensure even cooking all the way through.

  2. Add the vanilla extract or cold coffee and stir it in.

  3. Now add the flour, cocoa powder and plant-based milk. Mix well until you have a smooth, slightly thick chocolate cake batter.

  4. Add the chocolate chips and mix them in. Use a teaspoon to smooth out the top evenly.

  5. Bake in the microwave for 50seconds to 1 minute and 45 seconds. Please see the recipe notes for the correct baking time for your microwave.
