These little cookies are edible name holders. Make them for parties with each child's name.
Heat oven to 350°F. Line 2 or 3 baking sheets with parchment paper. In a bowl, stir together flour, sugar, and orange zest. Whisk in egg whites until smooth. Add vanilla and butter, whisking until well combined.
Drop a tablespoon of batter onto prepared baking sheet. Using the back of a spoon, spread into a 4-inch circle. Repeat to make 4 circles per sheet. Bake 13 minutes, or until edges of cookies are brown and centers are golden. Remove from oven; let stand 10 seconds. Working quickly, lift cookie off baking sheet and immediately fold halfway over so it resembles a napkin holder. Stand cookie on a cooling rack. Repeat quickly with remaining cookies; they can only be shaped when warm. Cool baking sheets before spreading on another batch of batter.
Write or type notes on small pieces of paper and place in cookies.
