Italian Butter Cookies

I make these all times of year but especially
around Christmas and everybody loves them.
You can top these with colored frosting or
some colored sugar sprinkles or jimmies.
I also leave some plain for dunking in tea.

Ingredients:

8 oz. butter or margarine, room temperature
1/2 cup (4 1/2 oz.) sugar
3 egg yolks
1/2 tsp. vanilla
2 cups plus 2 tbsp. (10 oz.) flour

Directions:
Cream butter and sugar 5 minutes
at medium speed with electric mixer.
Add egg yolks and vanilla. Mix till blended.
Add flour and mix on low speed.
Pipe dough with bag onto ungreased baking sheet
into rosettes with #7 star tube.
Bake at 400 degrees F. for 7-10 minutes.
VARIATION:
Shape dough into 1-inch balls,
place on baking sheet and flatten slightly with hands.
Top with colored jimmies.
