Preheat the Oven:
Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper or silicone mats.
Cream Butter and Sugars:
In a large mixing bowl, use a mixer to cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.
Add Eggs and Vanilla:
Beat in the eggs one at a time, followed by the vanilla extract. Mix until well combined.
Combine Dry Ingredients:
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add this mixture to the wet ingredients, mixing just until combined.
Add Oats and Chocolate Chips:
Stir in the rolled oats and chocolate chips until evenly distributed.
Portion the Dough:
Use a spoon or cookie scoop to drop rounded tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart.
Bake:
Bake for 10–12 minutes, or until the edges are golden brown and the centers look slightly underbaked. The cookies will set as they cool.
Cool:
Allow the cookies to cool on the baking sheet for 5 minutes, then transfer them to a cooling rack to cool completely.
