Whipped Shortbread

Soft pillows of buttery perfection! I love Christmas baking. I get to make all my old favourites and give them away. People seem to enjoy receiving a homemade gift and I enjoy making them.
This is a classic, I'm sure you've made it before but in case you haven't here's my tried and true recipe.....

Whipped Shortbread
 1 lb. of butter (softened)
1 cup icing sugar
1/2 cup cornstarch
3 cups of flour
1/2 tsp of vanilla extract

Cream butter, sift dry ingredients and then add them along with the vanilla in a electric mixer and beat until the consistency of whipped cream.
Drop by teaspoon onto cookie sheet. May be decorated with sprinkles or red/green cherries.
Bake at 350F for 15 to 20 minutes.
Stores well in covered tin.

Well, I'm off to make some peanut brittle.
