Perfect (And Easy!) Shortbread - cooking recipe

Ingredients

1/2 cup cornstarch
1/2 cup icing or 1/2 cup powdered sugar
1 cup flour
3/4 cup softened butter

Preparation

Sift together the cornstarch, icing (powdered) sugar and flour.
Blend in butter until a soft smooth dough forms.
Shape into 1\" balls and chill 30 -60 minutes.
Place 1 1/2\" apart on a cookie sheet and flatten slightly with a floured fork. (omit if throwing sprinkles on, and/or don't like fork flattened shortbread - I don't and it still comes out just fine)
Bake 300' for 15-20 minutes. Transfer to a rack and cool. Watch that they don't brown, you want to pull them out while they still look a smidge underdone - the idea is that they do not brown on the bottom.
