Cinnamon Rolls - Frosting

1 cube butter or margarine
1/4 c. brown sugar
1/4 c. whipping cream

Bring to a boil and add about 3 cups of powdered sugar. You may need to add a little more cream or milk to bring it to the desired consistency (you don't want it too runny though). Add 1 tsp. vanilla. I usually start the frosting when I start the cinnamon rolls. That way it has time to cool down before I have to frost them. Enjoy!
