Mix peanut butter, 1/2 cup coconut sugar, beaten egg, and vanilla in a bowl until well-combined. Stir in chocolate chips.
Roll cookie dough into 1-inch balls, about 16 balls total. Place on a parchment-lined or nonstick cookie sheet.
Wet a fork and then dip the fork into the remaining coconut sugar and press balls in one direction and then in the other direction to form traditional peanut butter cookie crosshatch marks and to flatten.
Bake cookies 6 minutes on the middle oven rack, turning the baking sheet around and bake an additional 5-6 minutes. Allow to cool on the baking sheet for about 25-30 minutes before removing with a spatula. Enjoy!
