Line a baking sheet with parchment paper or spray with non-stick cooking spray.
In a small bowl, combine the oats, flour, salt, and baking soda. Set aside.
Whisk together the melted butter, brown sugar, and granulated sugar until no lumps remain. Then, whisk in the eggs and vanilla extract.
Fold in the flour mixture until mostly combined. Then fold in the chocolate chips.
Using a cookie scoop, or ice cream scoop, drop heaping tablespoons of dough onto the baking sheet, cover, and chill for one hour up to 3 days.
Preheat the oven to 375℉.
Bake until the cookies are golden around the edges and soft in the center, for about 8-10 minutes. Remove from the oven and cool on the baking sheet for 1 to 2 minutes. Transfer to a wire rack to cool.
Notes
Storing: Cookies will keep in an airtight container at room temperature for 3-4 days or freeze for up to 6 months.
