In a large mixing bowl, combine oats, nut butter, sweetener, and chocolate chips. Stir until all ingredients are incorporated, forming a sticky dough.

Use a tablespoon to scoop small rounds of the dough and place them on a lined baking sheet, leaving space between each cookie. Flatten each scoop gently.

Preheat your oven to 350°F (175°C). Bake for 10-12 minutes until cookies are golden brown around the edges.

Remove from the oven and let sit on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
