This is also from the Cookies for Christmas cookbook from yesterday:
Eggnog Thumbprints
3/4 cup butter or margarine
1/2 cup sugar
1/4 cup packed brown sugar
1 egg
1/2 tsp. vanilla
1/4 tsp. salt
2 cups all-purpose flour
1/4 cup butter or margarine
1 cup sifted powdered sugar
1 tablespoon rum (you may substitute 1 T milk and 1/4 tsp. rum extract for the rum)
Ground nutmeg

In a large mixer bowl beat 3/4 cup butter or margarine till softened.  Add sugar and brown sugar and beat till fluffy.  Add egg, vanilla, and salt and beat well.  Add flour and beat till well mixed.  Cover and chill about 1 hour or till easy to handle.

Shape into 1-inch balls.  Place 2 inches apart on an ungreased cookie sheet.  Press down centers with thumb.  Bake in a 350F oven about 12 minutes or till done.  Remove and cool.

For filling, in a small mixer bowl beat 1/4 cup butter or margarine till softened.  Add powdered sugar and beat till fluffy.  Add rum and beat well. Spoon about 1/2 tsp. filling into center of each cookie.  Sprinkle with nutmeg.  Chill till filling is firm.  Makes about 50.

I'm excited to go to the Eisenhower Public Library District tonight where my author friend Penny Blubaugh is a librarian. I'll be doing the Preserving Holiday recipes. That is always a lot of fun!
