Put all ingredients in a bowl and mix with a fork.
Roll small balls of dough (about 15g each) with your hands (or use a small cookie scoop) and flatten them on a baking sheet.
Wet a fork and press on cookies to create a criss cross pattern.
Bake 8 -10 minutes, until the edges are firm. (8 minutes = soft centre, 10 minutes = overall crunchy)
Let cool completely before eating. They are very soft when just out of the oven, but will become crunchy once cooled.
Store in an airtight container.

Notes
1.6 g net carbs per cookie. Makes 20 cookies. Buy peanut butter that contains 100% peanuts and nothing else. If you have a food processor, you can even make your own.I mixed a bit of sea salt into the dough and sprinkled a bit more on top. It's the salted caramel effect - sweet and salty together are just crazy good.
