Ingredients

  • 1 egg
  • 2 tablespoon honey
  • 1 ½ tablespoon coconut oil melted
  • 1 tablespoon almond milk or any type of milk
  • ½ tablespoon lemon juice approx. ½ lemon
  • cup flour all purpose or gluten free 1:1
  • 1 teaspoon lemon zest approx. ½ lemon
  • ¼ teaspoon baking powder
  • Whipped cream or Cool Whip or Truwhip (optional)
  • Lemon curd or lemon icing (see notes), optional

Instructions

  • In the bottom of a large coffee mug or in a separate bowl, whisk together the egg, honey, coconut oil, almond milk, and lemon juice until well combined.
  • Add the flour, lemon zest, and baking powder and gently fold into the batter.
  • Pour the batter into a large coffee mug and place the mug in the microwave. Heat for 60 - 90 seconds until the cake has puffed up to the top and is semi-stiff when you press into it with your finger. The top will be a little wet at first but will solidify more as it cools down slightly.
  • Allow the mug to cool down a little before removing it from the microwave. Top with fresh whipped cream of choice and a drizzle of lemon curd or lemon icing (see notes).

Notes

Lemon icing - If you don't have lemon curd or don't want to make it, you can easily make a lemon royal icing. Mix together 2 tablespoons of powdered sugar with a teaspoon of lemon juice until well combined and drizzle over the warm cake.
