Cream together butter and sweetener. Add egg, vanilla extract and mix until combined.

Slowly add baking powder, salt, and almond flour, beating well after each addition. Cover and chill dough for 30-60 minutes.

Preheat oven to 350 and spray baking sheet with non stick cooking spray.

Scoop tablespoons of dough into balls and place on prepared baking sheet; flatten dough balls to form discs with fingers or by covering with plastic wrap and lightly pressing. Repeat with remaining dough, spacing cookies 2 inches apart.

Bake the cookies for 13-16 minutes or until lightly golden. Let cool on baking sheet for 5 minutes and then transfer to wire rack.
