This is my family's recipe. More Christmas cookies!
Ingredients:
Cream the butter and sugar together. Add the flavoring and flour. Roll into balls, flatten with your fingers, and prick with a fork (I don't know why that last step is important, but TRUST ME, it is. Put about four rows of fork-holes in).
Bake at 300oF for 20 to 25 minutes. They should still be fairly pale when they come out of the oven.
