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

Combine rolled oats and cocoa powder in a mixing bowl. Stir until evenly blended.

Add nut butter to the dry mixture and mix until crumbly, forming a sticky dough.

Drizzle in the sweetener and mix until the dough is sticky and cohesive.

Scoop the mixture onto the baking sheet, flatten each mound slightly and space about two inches apart.

Bake in the preheated oven for 10-12 minutes until edges firm, centers soft.

Cool on the baking sheet for 5 minutes before transferring to a wire rack.
