AHas anyone done a doll dress cake before? If so what did you use to make it a mixing bowl, cake pan etc.? Howmany servings did it make? Did you use icing or fondant to decorate?

I did a belle cake on top of a square cake (maybe 10 inch) I don't recall. I did the bottom cake with butterceam and covered belle with fondant.  I used the wilton wonder mold, but the doll was way too tall when I put her in ti. I had to build up the sides of the dress with fondant draping to compensate.  

AWith the wonder mold do you know how servings it makes
