However, we can make a few educated guesses:
* Walt Disney was known to be a fan of chocolate. He even had his own chocolate factory, Disney's Candy Kitchen, and he enjoyed chocolate treats. So, it's possible that he liked chocolate ice cream.
* Walt was also a fan of Mickey Mouse. There was a Mickey Mouse ice cream bar, and it's possible that he enjoyed that as well.
Ultimately, we can only speculate about Walt's favorite ice cream. It's a fun thought, though!
