Ingredients
  

For the shortbread crust

For the lemon filling

Instructions
 

  • Preheat the oven to 350 degrees F.
  • Line an 8 x 8 baking dish with parchment paper.
  • In a large mixing bowl, using an electric hand mixer, beat together the butter, powdered sweetener, and pinch of salt until creamy and well combined.
  • Stir in the coconut flour until a dough forms.
  • Transfer the mixture into the lined pan and press into place.
  • Bake the shortbread crust for 10 minutes, or until golden. Remove from the oven and allow to cool for 30 minutes.
  • In a separate mixing bowl, combine the softened butter, lemon zest, lemon juice, and powdered sweetener with an immersion blender or high-speed hand mixer. Once it is shiny and smooth, add your eggs, extra egg yolk, and mix well, before adding the coconut flour. Do NOT use an electric mixer here or you will over-beat the eggs and the topping will crack once baked. Use a hand whisk.
  • Bake for 20-22 minutes, or until the center is firm but still jiggles slightly.
  • Remove from the oven and let cool in the pan completely, before covering and placing in the refrigerator for at least 2 hours to overnight.
  • Once ready to serve, use a very sharp knife to cut into squares, sprinkle with extra powdered sweetener, and enjoy.
