Preheat your oven to 350°F (175°C).

In a large mixing bowl, combine oats, brown sugar, baking soda, and a pinch of salt.

Cream together the softened butter and brown sugar until fluffy. Beat in the egg and vanilla extract.

Gently fold the wet ingredients into the dry mixture until just combined.

Fold in the chocolate chips until evenly dispersed.

Using a tablespoon, scoop the dough onto a lined baking sheet, spacing them about two inches apart.

Bake for 10-12 minutes, or until the edges are golden brown.

Let the cookies cool on the baking sheet for about 2 minutes before transferring to a wire rack.
