Hi Silvia – you would follow the same method for a 10″ cake. The largest ball shaped pan I’ve seen is 10″ and then you’d place it on top of a 10″ round cake. Follow the directions that come with the ball pan regarding how many cups of batter you’ll need for your desired size.

No, unfortunately we do not have a specific amount noted. However, just start with a small drop of food coloring and build until you get the desired shade. It’s always easier to add more color but hard to remove too much.

Sure, you could substitute tempered white chocolate for the candy melt. Fondant would work as well!
