I've never made one but I can picture a 9 x 13 cake and on the top use wide strips of fondant, to resemble the noodles. You could "ruffle" the edges on the fondant using a ball tool. Use icing on the sides, to resemble the cottage cheese and whatever you made for spaghetti sauce on your spaghetti cake could be made for the sauce on this cake. Good luck, can't wait to see a pic!!
