Shortbread Cookies

This is one of my best tasting cookies.
The dough is simple to make in the
food processor and it always stays
together beautifully when handling.
An excellent dough for a cookie press.

Ingredients:
1 cup butter, cold
1/2 cup confectioner's sugar
1/2 cup cornstarch
1 1/2 cups flour
1/2 teaspoon vanilla

Directions:
In a food processor,
process butter with confectioner's sugar
until well creamed, about one minute;
you may have to scrape down the sides.
Add remaining ingredients and
process with several on/off turns,
just until dough is well mixed
and begins to gather together
in a ball around the blade.
What I do now is wrap this dough
in wax paper and put it in refrigerator
Shape rounded teaspoonfuls of
dough into small balls.
Place on an ungreased cookie sheet
lined with parchment paper and flatten,
using a fork dipped in icing sugar.
Bake at 350 degrees F. for 12-15 minutes,
watching carefully;
edges should be very lightly browned.
