In a large mixing bowl, combine rolled oats, chocolate chips, and creamy peanut butter. Fold until the oats are well-coated.

Drizzle honey or maple syrup over the oat mixture and stir vigorously until fully incorporated.

Line a baking sheet with parchment paper and scoop out portions of the dough, shaping them into cookies.

Place the baking sheet in the refrigerator and chill for at least 30 minutes to firm up the cookies.

Remove from refrigerator and serve cool or at room temperature, pairing with milk or a plant-based alternative.
