The Science of the Best Chocolate Chip Cookies

Most traditional chocolate chip cookie recipes start with the same basic ingredients and technique: butter and sugar (a mix of white and brown) are creamed together with a touch of vanilla until fluffy, eggs are beaten in one at a time, followed by flour, salt, and some sort of chemical leavening (baking soda, baking powder, or a bit of both). Other than the small amount in the butter, eggs are the main source of water in a cookie dough recipe. Going back to my initial problem of wanting the flavor of browned butter but disliking the way it prevented sugar from properly dissolving, I asked myself, what if I were to flip the script for these cookies: instead of creaming sugar and butter and adding eggs, why not beat together the eggs and sugar then add the butter?
