  • ½ cup butter, unsalted softened
  • ½ cup erythritol
  • ½ cup coconut flour
  • ½ teaspoon baking powder
  • ½ teaspoon salt
  • 3 medium eggs
  • 3 tablespoons water
  • 2 tablespoons lemon juice


  • 3 oz cream cheese softened
  • ¼ cup blackberries
  • 2 tablespoons cream, heavy or whipping
  • 2 tablespoons erythritol powdered


  • Preheat the oven to 180C/350F degrees.
  • Whisk the butter and erythritol together until creamy
  • Add the eggs, one at a time
  • Add the lemon juice and water. Keep whisking until smooth
  • Stir the dry ingredients into the wet and mix well. If the batter seems too thick add more water. It should resemble cake/pancake batter.
  • Place the batter into cupcake cases ¾ of the way up and bake for 20-25 minutes until the tops spring back lightly when touched.
  • Remove and cool in the pan.

Make the Frosting

  • Blend the topping ingredients until smooth. I used a hand blender but feel free to do an upper arm workout and try it with a spoon or fork!
  • Slather the frosting over the cupcakes and decorate with blackberry
