I found this great recipe on What’s Cooking America.  I made them for a tea party this week and they were AMAZING.  A delicate cookie with an absolutely delicious lemony frosting.  Perfect for a tea party or a baby/bridal shower.

COOKIE INGREDIENTS:
2 cups butter, room temperature*

2/3 cup powdered (confectioners’) sugar
1 teaspoon grated lemon zest
1/2 teaspoon pure vanilla extract
2 cups all-purpose flour
1 1/2 cups cornstarch**

Lemon Frosting (see recipe below)

* Very important – please read! You must use room temperature butter or these cookies turn out all crumbly.
** Yes, this is correct – use 1 1/2 cups cornstarch.

DIRECTIONS:Preheat oven to 350 degrees F. In a large bowl, beat butter until creamy looking. Add powdered sugar; mix until light and fluffy. Add lemon zest and vanilla extract; beat well. Add flour and cornstarch into butter mixture and mix well until well combined. NOTE: At first the dough will look dry – but don’t worry, as the dough slowly comes together as you mix it and the butter melts into the dry ingredients.

Do not refrigerate this dough, as the butter will harden and make the dough unmanageable for rolling to a ball. Using your hands, roll cookie dough into 1-inch balls. Place onto ungreased cookie sheets and bake 15 minutes or until bottoms are light brown. Remove from oven, carefully remove from baking sheet, and cool on wire cooling racks (when warm the cookies are delicate).

When cookies have cooled, spread Lemon Frosting onto top of cookies.

Yields 6 dozen cookies.

Lemon Frosting:

This recipe makes enough for a double batch of cookies.

1/3 cup butter, room temperature
1 teaspoon grated lemon zest
1/3 to 1/2 cup freshly-squeezed lemon juice
4 cups powdered (confectioners) sugar

In a medium bowl, combine butter, lemon zest, lemon juice, and powdered sugar; stir until well mixed. NOTE: Additional lemon juice may be needed to get the frosting thin enough.
