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

In a large mixing bowl, combine the oats, nut butter, sweetener, and chocolate chips until a cohesive dough forms.

Scoop out portions of the cookie dough and roll them into balls about one inch in diameter, placing them on the prepared baking sheet.

Flatten each dough ball slightly with the back of a spoon, aiming for about half an inch thick.

Bake in the preheated oven for 10–12 minutes, until the edges are golden brown and the centers are slightly underbaked.

Remove from oven and cool on the baking sheet for about 5 minutes before transferring to a wire rack to cool completely.
