There are a slew of Girl Scout cookies that I couldn’t live without. Thin Mints are always the first thing on our yearly order for the long-running Girl Scout annual cookie fundraiser. Thanks-A-Lot chocolate-dipped shortbread would be a favorite, too, if only we could order them in Colorado. And these, the dainty little Lemonades. A favorite lemon-flavored take on the Thanks-A-Lot shortbread cookie. They make a gorgeous addition to tea-time, or a perfect post-dinner snack. And did I mention midnight snack? Oh, yeah. They’re good for that, too. Light, crispy, and so simple to make, you won’t believe how lovely these little cookies are to make.
Girl Scout Cookies Copycat Recipe: Lemonades
1 cup butter, softened
1/2 cup confectioners’ sugar
1/4 cup cornstarch
1 1/2 cups all-purpose flour
zest of 1 lemon
In a stand mixer, cream the butter, then slowly add the remaining ingredients until mixture sticks together when pressed into a ball. Roll the dough until 1/4″ thick. Cut out with a small cookie cutter. Transfer to a baking sheet and bake in an oven preheated to 375 degrees for 11-14 minutes, or just until the cookies have set. Serve with a sprinkling of lemon zest and sparkling sugar, if desired. Enjoy!
