Oatmeal Chocolate Chip Cookies

(equivalent of 16 tablespoons) unsalted butter, (at room temperature)

dark brown sugar, (packed (light brown sugar works))

vanilla extract

large eggs, (at room temperature)

cornstarch

baking soda

scant 1 teaspoon salt ((I use fine sea salt))

old fashioned oats, (not quick oats)
