Pre-heat oven to 350F and line an 8x8" square baking pan with parchment paper
Mix melted coconut oil or Betterine in a bowl.
Add 1 cup of almond flour, 1/4 cup of sugar and a pinch of salt. Mix well
Pour into the pan and using (damp) hands, press the crust into the pan
Bake for 15-20 minutes (watch it carefully that it doesn't get too brown) and let cool for 10 minutes
In another medium-sized bowl, combine the lemon juice, extract (if using), eggs, 3/4 cup of sugar or Swerve, 3/4 cup of almond flour and a pinch of salt. Whisk together to smooth out any lumps in the batter
Pour filling onto cooled crust and bake for 22 minutes until just barely jiggly in the middle. I over-baked mine for 1-2 minutes which made it crack but that's okay, it's still delicious! Dust with powdered sugar or Swerve and cut into squares and enjoy!
