Preheat oven to 350 degrees F and line large baking sheet with unbleached parchment paper. Set aside.
In a large bowl, add peanut butter and maple syrup. Stir with spatula until smooth. Dough will thicken as you keep mixing.
Using small trigger scoop, scoop the cookie dough and release on a baking sheet, leaving 1.5 inches in between. Using a fork, press on cookie dough balls to flatten them and make a pattern.
Bake for 10 minutes before any visible browning occurs and cookies are still soft.
Remove from the oven and let cookies cool for about 30 minutes or until hardened right on a baking sheet. You can transfer them after to cool off more on a cooling rack, if you want.
