Gluten free sugar free peanut butter cookie

This is a simple recipe, and it's delicious. What no one will know is that you skipped the sugar for a zero calorie alternative, leaving a high protein, low calorie sweet that can serve as a granola bar while tasting like dessert. Enjoy!
Ingredients:

• 1 Cup natural unsweetened peanut butter
• 3/4 Cup erythritol or lakanto crystals
• 1 egg
• 1 tsp baking powder
• 1/2 tsp salt
• 1 tsp vanilla
• optional 1/4 cup carob or chocolate chips (these will add sugar)

Bake at 325 on stoneware pans for aprox 17 minutes. If baking on metal pans, start checking at 11 minutes. These will need to cool completely before being removed from pans. If you remove them when they are still warm, they will crumble, so let them set. Enjoy!
