I have tired to pm the decorator,but received no answer. So I was wondering how you would go about carving this style of booty. What size pan? Do you think you could make it from a 9x13 or would it need to be bigger? I've done one out of a 10" heart-that seemed simpler to me! But my friend likes the look of this cake better than the heart.
Thanks for any help!

My kids are laughing at me because I was sitting here staring at the picture trying to figure out what pans were used for it. The decorator's profile says she's from Finland so maybe it's a language barrier keeping her from answering you.

I think you could do it with a ball pan on top of a sheet, then carve.

When I made my Hooters cake I used a 11x 15 as the base and the boobs where made from the sports ball pan. I would think that a tushy cake would be about the same. HTH!
