In a large mixing bowl, combine your peanut butter with maple syrup until combined. Cover the bowl and freeze for 45 minutes or refrigerate for two hours.
Preheat the oven to 180C/350F. Line a large baking sheet with parchment paper.
Remove the chilled cookie dough from the freezer or fridge. Using your hands, roll out balls of dough and place them onto the parchment paper. Press down on each cookie dough ball into a cookie shape.
Bake the cookies for 10-12 minutes, or until the edges look golden brown. Remove the cookies from the oven and let them cool completely, before carefully removing from the baking sheet.
