This cake was for my daughter's 8th Bday. It is all chocolate cake using the 123 Gluten Free mix, which works great for layer cakes. For the doll, I used the insert from a Betty Crocker ball set, which is 6in - so I stacked it in 6 in rounds for height. The bottom layer is 8in rounds. It was very top heavy, so needed a lot of dowels to keep it together. The dancer still leaned a bit to the left, but it held together fine and made it to the party! Buttercream with fondant accents.
