  1. Preheat oven to 350°F. Line the bottom and sides of an 8x8" square baking pan with parchment paper, leaving an overhang on all sides.

  2. Make the crust: In a medium bowl, combine coconut flour, almond flour, monk fruit, and lemon zest. Add the coconut oil and mix until the dough forms. Pat with your hands to bring the dough fully together then press evenly into prepared pan. Bake for 5-8 minutes, or until golden brown around the edges. Remove from the oven and allow to cool completely.
  3. Make the filling: In a medium-sized bowl, whisk together the eggs, lemon zest and monk fruit. Add the coconut, followed by the lemon juice, mixing well until smooth and no lumps appear.
  4. Pour filling over cooled crust and bake until just set about 17-22 minutes. Be careful NOT to OVERBAKE. Remove the pan from the oven and allow to cool in the pan for 30 minutes.

  5. Place in the refrigerator to chill until firm, about 2 hours and up to overnight.
  6. Once chilled, lift the parchment paper out of the pan using the overhang on the sides and cut into squares.

Bars can be made ahead of time 1-3 days in advance and store covered tightly in the refrigerator until ready to serve. Bars can be frozen for up to 3 months. Thaw overnight in the refrigerator before serving.
