During Covid when so many cast members were laid off, some started cottage industry home bakeries. These are still around, but it takes some searching. Most do beautiful work, are more affordable than a Disney custom cake (IF you can get one... Disney seems to be actively phasing this out), and they will deliver to your resort (not sure about delivery to restaurants). There's a facebook group, Ears to Each Other, that lists some of these independent bakers. I've used Olivia's Kitchen and Cheat Day Factory and been happy with both.
