Lemonade Cookies

Got this from a cookbook done by our Med/Surg department at work. These sound YUM!

3 cups sifted flour
1 tsp baking soda
2 eggs
1 cup softened butter
1 cup sugar
1-6oz can frozen lemonade

Cream the eggs, butter and sugar with 1/2 of the lemonade in mixer. Add other ingredients, leaving 1/4 of the lemonade out. Drop onto baking sheet and bake 8 minutes at 400 degrees. Brush cookies with remaining lemonade and sprinkle with sugar (wonder if maybe it's powered sugar?)

If you try it, let me know what you think!
