Santa’s favorite food is cookies. We leave him milk and cookies every year on Christmas Eve as a thank you for the presents he brings us. Why would we leave these foods out if they weren’t his favorite, or at least, one of the favorites he has?
Other suggestions for foods to leave out for Santa - other favorite foods he has - include punch (in case he’s almost been caught and wants something kind of strong) and cocoa with cinnamon in it. This will keep him awake if he’s on his last few houses. Furthermore, he loves it when people leave food for the reindeer. Apples, reindeer moss, and hay are three examples of good food you could leave for the reindeer if you wished to.
