Wouldn't that be...you know....really delicious? That's basically the traditional birthday cake frosting of long ago. I used to be a serious frostaholic as a kid. One year, I refused to have guests to my birthday party, so I could eat all the cake myself. When I was in High School, they came out with cake frosting in a can. Oh, man, the frosting habit I developed out of THAT. I never really got over it, but they make frosting differently now, and it doesn't taste the same.
Oh, man, if there were a way to lose weight eating traditional cake frosting, I would worship you as a god.
