Flower Sugar Cookies

Directions

1. 1
   For the cookies: Beat the butter in a large bowl with a handheld mixer until fluffy. Scrape down the sides of the bowl, add brown sugar, and continue beating until light, 2 to 3 minutes.
2. 2
   Whisk the water and egg white powder in a medium bowl until foamy and smooth. Gradually whisk in the confectioners' sugar to make a smooth icing.
3. 3
   Add egg and vanilla extract, beating until smooth. Gradually add the 2 cups flour and salt while mixing slowly to make a rough dough. Press dough into a ball by hand. Lightly dust the cookie dough with flour and roll it between 2 pieces of waxed paper into a 1/4-inch-thick disk. Slide the disk in the paper onto a cookie sheet and freeze until firm, about 20 minutes (or refrigerate about 1 hour).
4. 4
   Spread a layer of icing over the entire surface of the cookies (or just in the center, if desired) with the back of a teaspoon.
5. 5
   Evenly space the racks in the oven and preheat to 350 degrees F.
6. 6
   Place sprinkles, chocolate chips, or candies in the center of the cookies.
7. 7
   Transfer the dough to the work surface and remove the top sheet of paper.
8. 8
   Let rest until the icing sets, about 30 minutes.
9. 9
   Cut into cookies with a 4-inch flower or other decorative cutter and transfer them to a parchment-lined or nonstick baking sheet. Press excess dough together and roll and cut into cookies as well.
10. 10
    Bake until cookies' edges are golden, about 20 minutes. Cool on a rack.
