Whipped Shortbread - cooking recipe

Ingredients

1 lb unsalted butter, softened
1 cup icing sugar
3 cups flour, pre-sifted
1/2 cup cornstarch

Preparation

With and Electric mixer, beat butter & Icing sugar until it stands up like egg whites.
In a seperate medium bowl, combine flour and corn starch. Add slowly to butter and icing sugar mixture. (I find when your mixer starts to power out, then use a wooden spoon to take over, but please try to use the mixer as long as possible).
Drop from teaspoon onto cookie sheet about 2 inches apart. Top cookies with jub-jubs, bar cherries, or anything really. My oldest son loves smarties on his. Imagination is up to you.
Bake at 300 for approx 30 minutes until bottom edges turn a light brown.
(Because all ovens vary please start checking them at about 20-25 minutes).
