I like everything about the 3rd one best - the cake image (which you need to have since it has this sugar-aholic thinking I need a piece of cake already)... and the fonts used. I especially like the "cake" with pink & its' font. This may be a weird suggestion, so take it or leave it, but what if you had her change the little whipped-cream on top to swirl the other way, or a little wider at the base & then point up... the only reason I mention it, is because my mind said "steam" when I saw it... but maybe that's because I just drew steam on a cake that way (copied from clip-art). I love it how it is though! Aren't logo's fun! I like yours!
I like the first one - it made a positive impression on me at first glance. I, too, would be interested in contacting your designer for a logo (please pm me if that's okay).
