2 c flour
1 c unsalted butter
1/2 c icing sugar (confectioner's sugar) or 10X
Recipe
Mix together the flour, margarine, and icing sugar and knead like bread for a MINIMUM of 15-20 minutes.
Chill for about an hour.
Roll out and cut into bars, poke fork holes into the cookie for design, and bake at 300 degrees F. for 15-20 minutes.
It has to be kneaded or it doesn't turn out flaky. If these are done right, you can take a bite out of them, and it will just dissolve in your mouth.
I don't roll out the dough into bars. I just pick off dough and roll into balls. I then use a fork that has been dipped in icing sugar to flatten them slightly before baking.
You want them cooked, but you don't want ANY color to them at all. They are perfect if the bottoms are just starting to change color a bit.
