Preheat your oven to 350°F.
Line a baking sheet with parchment paper.
In a large mixing bowl, combine the peanut butter, rolled oats, brown sugar, and vanilla extract. Mix until well combined.
Fold in the dairy-free chocolate chips.
Using a tablespoon, scoop the cookie dough onto the prepared baking sheet, spacing them about 2 inches apart.
Flatten each cookie slightly with the back of the spoon.
Bake for 10-12 minutes or until the edges are golden.
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
