Preheat the oven to 350 F. Line a large baking sheet with parchment paper.

Add the butter to a saucepan over medium heat. Let the butter melt and then brown, stirring frequently (see notes for tips on how to brown butter - it should take about 5-8 minutes).

Pour the brown butter into a large bowl and set aside to let cool for a few minutes.

Once cool, add the brown sugar, eggs, and baking vanilla to the bowl. Mix well to combine.

In a separate bowl, add the flour, oats, baking soda, and salt. Mix well to combine.

Gently fold the dry ingredients into the wet ingredients. Mix until just combined, being careful not to overtax.

Fold in the chocolate chips, reserving some to add to the tops of the cookies.

Scoop the cookies into balls about the size of a heaping tablespoon. Roll and flatten them gently and place onto the lined baking sheet. You’ll have about 20-25 cookies.

Bake the cookies in the preheated oven for 8-9 minutes. Let cool for a few minutes and then serve.
