Notes
Store in an airtight container to keep fresh for up to 5 days. These cookies freeze well.*Light-colored baking sheets are what I use for all of my cookies. Lighter metal bakes more evenly than dark and doesn’t brown the bottoms of the cookies too quickly. If using a dark metal baking sheet, adjust the baking time and watch the cookies to prevent burning.** You can use a stand mixer with a paddle attachment or an electric hand mixer.
