Thanks for your feedback. I don't have any offers yet. I am thinking of creating a brand, I have at least 2 other types of cake were the name is free and I think have potential. We will see what happens, Always open to offers though.
This is also very niche and would require usually a physical location. I wouldn't want a birthday cake shipped to me as there's just so much that can go wrong with a shipment of food that can spoil (or get wrecked) by the special day.
