MEXICAN WEDDING COOKIES (POLVORONES DE CANELA)

Steps:

• In a medium bowl, whisk together flour, salt, and 1 1/2 teaspoons cinnamon.
• In the bowl of an electric mixer fitted with the paddle attachment, beat together butter and 1 cup confectioners' sugar on medium speed until smooth. Beat in vanilla. Reduce speed to low and gradually mix in flour mixture until incorporated. Shape dough into a square and wrap in plastic; refrigerate 1 hour.
• On a lightly floured surface, roll out dough 1/2 inch thick. Using a 2 1/2-inch round cutter, cut out cookies. (Scraps can be rerolled once.) Divide evenly between two parchment-lined baking sheets. Using a 3/4-inch round cutter, cut out a hole in the center of each cookie. Refrigerate until firm, about 30 minutes.
• Meanwhile, preheat oven to 350 degrees. Bake, rotating halfway through, until edges begin to brown, about 20 minutes. Let cool on sheets 5 minutes, then transfer to a wire rack and let cool completely.
• In a small bowl, stir together remaining 2 teaspoons cinnamon and 1 cup confectioners' sugar. Working with one cookie at a time, toss in cinnamon sugar until thoroughly coated. Cookies can be stored in an airtight container at room temperature up to 3 days.
