Answer:
1. Mix melted browned butter with sugar, brown sugar, and vanilla until combined. The mixture will be very soft and greasy.
2. Add eggs and egg yolk one at a time, mixing for about 30 seconds after each addition. You’ll notice the mixture lightens in color and starts to thicken.
3. Wait for a few minutes, then mix again for 30 more seconds. This will lighten the color and texture even more.
4. Add the flour, baking soda, and salt and stir until combined. This will take a few minutes mixing by hand, but it will com together to make a thick cookie scoop.
5. Portion onto cookie sheet and bake for 9-11 minutes.
6. Add coarse see salt to warm baked cookies, if desired.
