Preheat your oven to 350°F (175°C). In a large mixing bowl, combine rolled oats, creamy peanut butter, and honey or maple syrup. Stir until thoroughly blended.

Line a baking tray with parchment paper. Scoop portions of the mixture onto the tray and flatten them slightly.

Bake in the preheated oven for 10 to 12 minutes, until the edges are golden brown and the centers remain slightly soft.

Once baked, let the cookies cool for about 5 minutes on the tray before transferring them to a wire rack.
