I just made Caramel cupcakes with Butterscotch Frosting. They aren't that exciting to look at, being shades of tan, but they are delicious! Almost too rich, and I suggest you try them. :)
http://www.recipezaar.com/187751 Be aware the recipe only makes 12 small-ish cupcakes. Of course, each small-ish cupcake probably will be a thousand calories. Also, I had plenty of leftover frosting, using the amount called for in the recipe.
Hope you enjoy!
