So its my 30th bday on saturday, and i want a huge cake!! I want to make something that i have not done before and make it grand. the problem is, who is going to eat it? I was thinking of doing half in dummies and 1/2 cake. Is it dumb to make your won cake? Did i mention that we are on weight watchers, so who is going to eat it?

Then make 6" cake to eat and everything else a dummy.

I agree with CakeForte. Make yourself a 6'' and the rest a dummy.
NO, it isn't stupid to make your own BD cake. I made mine this yr. and
all it was was a 6". Have a wonderful BD.

6" real cake sounds great. And just how many points is in one lick from the knife of buttercream...I do WW online, works great....when I actually stick to it.
