A Twitter friend was asking for an easy Christmas Cookie recipe. This one is even better than easy - you can make it ahead! Enjoy!

Brown Sugar Christmas Cookies
1 cup all purpose flour
1/4 tsp. baking soda
1/8 tsp. salt
1/4 cup butter, softened
2/3 cup packed light brown sugar
1 tsp. vanilla
1 large egg white
Sanding sugar or any decorating sugar

Mix flour, baking soda, and salt in a bowl and set aside.
Beat butter with mixer at medium speed until light and fluffy.
Add sugar to butter, beating at medium speed until blended.
Add vanilla and egg white and beat well.
Add flour mixture, stirring until well blended.
Dump the dough out onto waxed paper and shape into a 6 inch long log.
Pour sanding sugar onto waxed paper and roll log through it to coat all around the log.
Wrap the log in the waxed paper and place in zip top plastic bag and refrigerate or freeze until you are ready to use!

Preheat oven to 350.
Remove log from waxed paper and slice into 1/4 inch slices.
Place about an inch apart on baking sheet coated with cooking spray.
Bake at 350 for 8 to 10 minutes.
Remove from pan and cool on wire racks.
Makes about 2 dozen.
