Preheat oven to 375 degrees F and line a baking sheet with parchment paper. Set aside.
In a small sauce pan, melt the butter on low heat until melted. Increase heat until butter sizzles. Continue to stir until butter starts turning brown and light specs form at the bottom of the pan. Remove from the heat and pour into a medium bowl.
Meanwhile, whisk flours, baking powder, baking soda, and salt together in a small bowl. Set aside.
Whisk sugars into the browned butter until combined. Add eggs and oil and whisk until combined. Add milk and vanilla and whisk until combined.
Slowly in 2-3 increments, stir in the flour mixture with a spatula. Stir until just combined (be careful to not over mix). Gently fold in chocolate.
Using a cookie scoop, scoop the cookies into 1- 1/12" round balls onto lined baking sheet. Sprinkle each with a pinch of sea salt. Bake for about 10 minutes. Be careful to not over bake so they don't end up dry. Then bake the remaining cookies.
Notes
Store cookies in airtight container. They'll be good for 3-4 days if properly stored.  You can also freeze the cookies prior to baking and take a few out at a time.Â
