I have a request to make a hex shaped cake for 250 servings. I only have the four pan set that makes like a cake for 120 or so. Does anyone know if they make larger pans besides the 15 12 9 and 6?
I haven't seen hex pans bigger than that (unusual shape!), but perhaps someone else can help you with that.
Have you thought of discussing doing sheet cakes to make up the difference?
