Thick and Soft Chocolate Peanut Butter Cookies (gluten-free)

+ 2 tablespoons creamy peanut butter (i.e. one heaping cup – I prefer creamy honey roasted; plain or crunchy may be used; do not use natural or homemade peanut butter, it’s too runny)

light brown sugar, packed (dark brown may be substituted)

large egg

vanilla extract

unsweetened natural cocoa powder (Dutch-process or Hershey’s Special Dark may be substituted)

baking soda
