Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

In a mixing bowl, combine rolled oats, peanut butter, and honey (or maple syrup) and mix until a sticky mass forms.

Add cocoa powder and stir until fully incorporated into the dough.

Scoop even amounts of dough onto the baking sheet, spacing them 2 inches apart.

Bake for 10-12 minutes until the edges are firm and centers are soft.

Allow to cool on the sheet for 5 minutes, then transfer to a wire rack.
