Preheat the oven to 180C/350F. Line a large baking tray with parchment paper.
In a large mixing bowl, combine the almond butter, brown sugar, and egg until completely mixed. If using chocolate chips, fold through at the end.
Form 12 balls of cookie dough and place them on the lined tray/cookie sheet. Place balls of dough 2 inches apart. Press down on each ball into a cookie shape. Bake for 10-12 minutes or until just golden on the edges.
Remove from the oven and let cool completely on the cookie sheet.
