That's a random silly idea that popped in my mind all of a sudden.
Try with a prompt that sounds like:

SuperBreadman, A superhero made out of bread, with a bread head and a face made out of bread with pastry eyes, bread shoulders, bread arms, bread hands with bread fingers, and his entire body made out of bread, with bread legs. Superhero bread costume made of bread slices and breads, by SuperBreadman
