I just improvised cream-cheese frosting and it literally tastes like cheesecake! YAHOO! Here's what I did:
1 stick butter, softened
8 oz cream cheese, softened
---> cream these together until completely mixed.
1 cup confectioner's sugar
----> mix in well until it looks like frosting
1 tsp-1 tbsp vanilla extract
----> mix that in until it looks like frosting again.
I put it over a boxed carrot cake (the Duncan Hine's extra-fancy version where you rehydrate actual carrots and raisins). We shall see how it goes. I would have baked a real carrot cake, but I wasn't feeling THAT motivated today. And everyone knows that frosting is the best part, right? ;)
