Position two oven racks in the middle of the oven, and preheat at 350°F. Line two baking sheets with parchment paper.

In a medium bowl, combine Almond Flour, stevia, Baking Powder, and salt, whisking until well mixed. In a large bowl, whisk eggs, butter, Lemon juice, and lemon extract together until well blended. Add the flour mixture and stir with an electric mixer for one or two minutes to make a very thick, very sticky batter.

Drop the dough onto the prepared pans, using about one heaping tablespoon of dough per cookie, or roll the portions of dough into balls. Space the cookies about two inches apart.

Bake for 8 minutes, then rotate the pans and switch racks and bake for another 6-8 minutes, until cookies are lightly golden and firm to the touch.

To make the Icing, combine the stevia and Lemon Juice in a small bowl, and whisk until well blended.

Let the cookies cool on the pans for about three minutes, then brush the tops with the icing, or dip them straight in the icing. Place the glazed cookies on a wire rack and let cool for an additional 15 minutes before serving.
