  • 1 egg
  • 2 tbsp double cream
  • 2 tbsp coconut flour
  • 10-12 blueberries
  • 2 tbsp fresh lemon juice
  • 1/4 tsp vanilla extract
  • 2 tbsp granulated erythritol
  • 1/4 tsp baking powder
  • pinch of salt


  • Whisk egg, double cream, lemon juice, and vanilla extract together.
  • Mix coconut flour, erythritol, baking powder and salt in a separate bowl.
  • Mix dry and wet ingredients. Softly mix in the blueberries.
  • Pour the batter into a mug. Microwave for 60 seconds at 800 watts. Check out with a toothpick whether it’s cooked. If not, continue microwaving and continue checking every 20 seconds.
  • You can add some whipped cream on top for that extra moisture if you wish. That’s completely optional though.
