This cake is as PG-13 as I get! To make any unique cake shape the key is attaching pieces. I think it is too hard to cut multiple layers of an odd shape exactly the same so I go an easier route. Bake your cake in large squares that you can cut down to size. Frost between the layers and then cut out squares, rectangles, whatever shapes you need and place/frost them together to get the rough outline of your cake. For this cake I started with a rectangle for the torso and rounds for the chest. I used a round pan to trace the shape of the waist and to fill in and smooth out the shape I took the scraps of cake, crumbled them and added a little frosting until it was mold-able and then used it like a filler, filling in all the cracks, adding a little roundness where I needed it and the bonus is that is tastes really good and will help keep your cake moist. Once I had the shape I wanted I refrigerated it until very cold and firm before applying my crumb coat. For other sculpting examples see my “Puppy” and “Guitar” cakes.
a little faith and a lot of frosting
