Preheat oven to 350 degrees. Prepare a large baking sheet.
Mix almond flour, sweetener, baking powder, baking soda, and salt in a bowl.
Add cold butter and mix using a pastry blender or mixer until mixture resembles coarse crumbs.
Whisk egg, lemon juice, and lemon zest, in a small bowl and stir into flour mixture until moistened; turn out onto a lightly floured (almond or coconut flour) surface.
Knead dough briefly for about 4 turns. Pat or roll dough out into a 1 inch-thick round.
Cut into 8 wedges and arrange on a baking sheet leaving 2 inches between each wedge.
Bake for 18 minutes or until bottom edges are lightly tan. Let cool on wire rack.
