2 sticks unsalted butter at room temp
1 cup powdered sugar
1 large egg
2 1/2 tsp vanilla extract, or vanilla bean, yum!
Lemon zest, I didn't use it because I didn't have it :(
2 1/2 cups AP flour, all purpose
1 tsp salt
Cream butter and sugar, until light and fluffy..this will take a few minutes. Beat in egg, vanilla, zest (if using) and salt. Mix in flour on low speed until incorporated. Form dough into a ball and wrap in plastic wrap, or place in ziploc bag. Refrigerate one to two hours or up to 24 hours. Once dough is chilled, roll it out onto a well floured work surface. I like to flour the top of the dough a bit too so it doesn't stick to the rolling pin. Roll a 1/4" thick. Cut cookies and place on a wax, or parchment lined pan. Bake 8-10 minutes (cookies will be slightly browned on the edges) in a 375 degree preheated oven. Cool cookies and ice with royal icing.
4 cups powdered sugar, sifted
2 tbsp meringue powder, this can be found at JoAnn or Michaels in the cake aisle..maybe at your local grocer?
Beat powdered sugar and meringue powder with water. You're going to want to beat for about 10 minutes until white and glossy. If you have never iced cookies before you might want to check out a tutorial. Thin icing is great for flooding the cookies as a base. If decorating them you want the icing to be thick.
