In a mixer add 1 Cup Packed Brown Sugar, 1/2 Cup White Sugar, 1 While Egg plus 1 egg yolk, 1 Tsp Pure Vanilla Extract and 3/4 Cup Melted Butter. The melted butter part is why I love this recipe...no waiting for softened butter.
Add your Dry Ingredients. 2 Cups Unbleached Flour, 1 Tsp Baking Soda and a 1/2 Tsp Salt. Turn your mixer on low to JUST combine the dry ingredients into the wet. Do not over mix.
Allow to slightly cool on the baking sheet before transferring to a cooling rack. Or just eat them warm out of the oven with a big glass of milk!
