Ingredients

Almond Flour Crust

Lemon Filling

Instructions

Almond Flour Crust

  • Preheat oven to 350°F. Line the bottom of an 8 x 8-inch baking pan with parchment paper (optional).
  • Combine the almond flour, monk fruit, and melted butter in a medium bowl and stir until everything is evenly moistened.
  • Press evenly and firmly into the bottom of the pan.
  • Bake for 12-15 minutes or until the crust is just started to lightly brown on the edges.

Lemon Filling

  • Whisk the eggs in a large bowl, then add the lemon juice, lemon zest, erythritol, monk fruit, and gelatin.
  • Pour over the prepared crust.
  • Place the pan back in the oven and bake for an additional 22-25 minutes or until the lemon topping is fully set.
  • Allow to cool, then place in the refrigerator for at least 1 hour to chill.
  • Cut into 9 even squares.

Notes

Tips and Techniques

  • If you prefer to use just one sweetener, I would recommend using just the monk fruit/erythritol blend. You would use 1/4 cup for the crust and 1/2 cup for the lemon filling.
  • You can dust the top of the lemon bars with a powdered erythritol, if desired. It does eventually soak into the tops of the bars so I would recommend not sprinkling it on until immediately before serving them.
  • Store leftover lemon bars tightly wrapped, or in an airtight container, in the refrigerator. Use within 3-4 days.
