Heat the oven to 350 F. Line 2 cookie sheets with parchment.
In large bowl, cream together the peanut butter, maple syrup, egg and vanilla.
In separate bowl combine the remaining dry ingredients and stir to mix. Slowly mix the dry ingredients into the wet ingredients.
Drop by 2 tablespoons per cookie onto a prepared cookie sheet. Press down a bit to form them into cookies — they won’t spread in the oven. Bake for 8-10 minutes. Do not overbake.
Allow the cookies to cool completely. Store cookies in an airtight container in the fridge.
