Ingredients

For the cake
  • 4 tablespoon almond flour extra fine, or 5-6 tablespoons ground almonds
  • 2 tablespoon heavy cream
  • 1 ½ tablespoon powdered sweetener 
  • 1 egg
  • 2 tablespoon lemon juice
  • ½ teaspoon baking powder
For the glaze
  • 1 tablespoon unsalted butter
  • 1 tablespoon heavy cream
  • Squeeze of lemon juice

Instructions

Cake
    Cup of Yum
  1. Grease 2 ramekins, mugs or 1 microwave-safe bowl with melted butter. I used a glass dessert bowl.
  2. Mix all dry ingredients - almond flour, sweetener and baking powder - in a separate bowl.
  3. Add all wet ingredients and mix thoroughly with a fork. If you find your dough is too liquid add more almond flour.
  4. Transfer batter into your bowl or mugs and level the top.
  5. Microwave on high for 90 seconds.
  6. Turn upside down onto a plate once cooled or enjoy straight from the bowl.
Glaze
  1. Melt the butter, then stir in the cream, lemon juice and sweetener.
  2. Let cool until the glaze begins to thicken. Spoon or pour over cake.
