This big batch of chocolate chip cookies is my go-to cookie recipe when I need to provide desserts for a crowd. I bake these cookies for almost every holiday or family gathering because they're a hit and easy to make.
In a large mixing bowl or the bowl of a stand mixer, combine cooled brown butter, white sugar, brown sugar, vanilla extract, salt, nutmeg, baking powder, and baking soda.
Start on a low speed to moisten, then increase speed to medium until batter is well combined, about 5 minutes. You may need to pause the mixer and scrape down the sides of your bowl halfway through the process to ensure your ingredients are incorporated.
Stop the mixer and add one egg as well as half of your flour/oat mixture. Beat until smooth before adding the second egg and other half of the flour and pulsed oats. Beat for about one minute.
Scoop golf-ball sized portions of your cookie dough onto ungreased aluminum baking sheets, with about 2 inches between each of them. Bake for 13-14 minutes.
