That should be pretty easy to just cut it out into that shape. I would do a cutout template bell, the size that you want it, cook yourself two 9 x 13 pans or two 9 inch squares or two 10 inch rounds (whichever will fit the size of your template) then put your template on top and just cut it out for both layers. put frosting in between the two cut out bells and frost. I am not sure but the picture above looks like it may have fondant on top of it.
As far as the bottom round on bell I am not sure about. Maybe rice crispies cereal? I am no expert so hopefully someone else here will be able to help you more than me. Good luck I am sure you will do a beautiful job!!!
AAs remnand said... And I would also say it's covered in white fondant. To make the bell, you could use modeling fondant or gum paste or marzipan or rkt, but if you have time I'm just thinking I wohl use a candy apple. It's so christmasy. Ok, the apple is not perfectly round, but it's something special to add. Either buy one or make one, with a cinnamon stick in the middle and red candy outside, which you could dust with gold luster dust...
AWow..thanks so much!! Yeah, might work with a round cake too...I'll search for a template and see what fits. Thank you!!!
AOh, and for the bell, I was planning on just rolling up a ball of fondant..it won't be too big :)
