Really short on time- does anyone have ideas to change the flavor besides cinnamon?

You add any flavorings you have on hand. One of my favorites is ginger and butterscotch ice cream topping, yum!

ive used canned frosting when ive been short on time or just for home fun baking.
ive added any flavoring i had in the house. also i add poweder sugar to make the frosting a bit firmer.
it seems to double the amount of can frosting.
