Rootbeer Glaze for Rootbeer Cookies
2 c. powdered sugar
1/3 c. butter, softened
1-1/2 tsp. root beer extract
2 Tbl. hot water

Mix powdered sugar and butter. Stir in rootbeer extract and hot water. Place wax paper under cooling rack. Spoon glaze over the cookies. This glaze will do a double batch of cookies. 

Another easy option is:
1 box yellow or spice cake mix
1 tsp. rootbeer extract
1 egg
1 stick of melted butter(but not hot)
Combine all ingredients.  Use a cookie scoop to get equal portions.  Flatten with the bottom of a flat glass that has been dipped in sugar.  Bake at 350 for 11-12 minutes, don't let the edges brown.  Let cool and spread with the same icing as above or add a bit more powdered sugar to thicken it up.  Spread a generous amount on the bottom of one cookie and sandwich with the bottom of another.  These are best if you let them sit overnight.  Good luck with that though.  :)
