Equipment

  • Baking pan
  • Mixing bowl
  • Measuring cups

Ingredients

For The Crust

  • 1 ½ cups almond flour
  • ⅓ cup butter
  • 2 tablespoon powdered erythritol

For the Filling

  • 3 eggs
  • ⅓ cup lemon juice
  • ¾ cup powdered erythritol
  • 1 cup almond flour
  • zest of one lemon

Instructions

  • (Make The Crust): Preheat the oven to 180C / 350F. Grease 20x30cm baking dish with butter.
  • In a bowl, add the almond flour, powdered erythritol and butter, mix well until combine.
    1 ½ cups almond flour, ⅓ cup butter, 2 tablespoon powdered erythritol
  • Spread the mixture equally in the baking dish while pressing on it with your hand to flatten it.
  • Bake for 10-15 minutes or until golden brown. Leave it to cool while you make the filling.
  • (Make The Filling): In a medium-sized bowl, whisk the eggs using an electric hand mixer until fluffy, add powdered erythritol, lemon juice and lemon zest whisk again until combined.
    3 eggs, ⅓ cup lemon juice, ¾ cup powdered erythritol, zest of one lemon
  • Add the almond flour, whisk until well incorporated.
    1 cup almond flour
  • Pour the filling over the crust and bake for 14-15 minutes. Leave it to cool down then sprinkle some powdered erythritol on top. Slice and serve.

Notes

  • I highly recommend using powdered sweetener because if you made these bars with granulated sweetener, they will turn out so grainy and not as smooth as you like.
  • Here is my trick when I don't have powdered sweetener on hand, I just grind some granulated sweetener in the grinder until fine.
  • I recommend using fresh lemon juice for better results.
  • To store: Keep them in the fridge for 2-3 days or in the freezer for 1-2 months.
