Preheat your oven to 350°F (177°C) and line a cookie sheet with parchment paper.

Combine peanut butter, maple syrup, and quick oats in a mixing bowl and mix until a thick cookie dough forms.

Scoop portions of the dough, roll into balls, and flatten to about 1/4 inch thick on the cookie sheet, spacing them with 1/2 inch apart.

Bake cookies for 9-10 minutes until the surface looks set and slightly golden.

Let cookies cool completely on the sheet before transferring to a wire rack.
