Add the peanut butter, brown sugar, egg, and vanilla to a mixing bowl and beat with an electric mixer until well combined.
Add the almond flour and baking soda and mix well.
Use a medium cookie scoop to scoop out 18 balls of dough onto a parchment lined baking sheet.
Use a fork to make a crisscross pattern in each ball of dough.
Bake for 8-9 minutes or until the cookies are set on the edges. Do not overbake.
Allow cookies to cool on the baking sheet for 10 minutes before transferring to a cooling rack.
Tips & Notes:
Any sweetener that bakes at a 1:1 ratio with sugar should work, but the taste and texture may be different than our tests. We use and love Lakanto and Swerve sweeteners.
The nutrition information was calculated with a peanut butter that is 4 net carbs per 2 tablespoons.
