Place rolls evenly spaced in a sprayed round cake pan. Cover with sprayed plastic wrap and let rise*.
In a small bowl combine butter, flour and hot water and mix until smooth. Spoon mixture into a sandwich bag. Push down into one corner of the bag and snip off a very tiny corner.
Remove wrap from risen rolls and draw a snowflake on the top of each roll with the butter mixture.
Bake at 350°F 15 minutes or until tops of rolls are golden. Adjust number of rolls for different pan sizes.
*If using Warm-N-Serv Rolls, draw snowflake while frozen and bake following instructions on bag.
