If you have a small amount of whipped topping left over, place dollops of it on a wax paper and freeze. Then place in an air tight container. When you need a quick topping for a dessert or some to go on a late night cup of hot cocoa you can just grab one out of the freezer.
I got this off the webpage "Living On a Dime Newsletter". Anyone who know me (my kids) know I love real cream. This is a better idea for my waist line than just downing the leftover cream.
