Peanut Butter Keto Cookies

0 Preheat the oven to 350°F, and set 2 of the oven racks to be as close to the center of the oven as possible.  Line 2 standard baking sheets with parchment paper.
1 In a large bowl, mix together the peanut butter, sugar, eggs, vanilla extract, baking powder, salt, and, if using, the chocolate chips. Stir until a smooth dough forms.
2 Scoop 20 cookies (10 per sheet) spacing them at least 1-inch apart on the baking sheet. Using a fork, press them down in a crisscross pattern until they are a ½- to -¾-inch thick.
3 Bake the cookies for 10-13 minutes, swapping the trays placements after the first 5 minutes (move the top tray to the bottom and the bottom tray to the top). Allow the cookies to cool completely before removing them from the tray to avoid crumbling.
4 Once cooled, enjoy your cookies! Store any leftovers in a sealed container at either room temperature or in the fridge for up to 5 days. Store in the freezer for up to 1 month.
