In the large mixing bowl, combine raisin bran cereal, milk and honey. Let the mixture stand until the cereal softens, about 10 minutes or so. The mushier the better.
In the small bowl, stir together the flour, baking powder, salt, sugar, and cinnamon.
Add the egg and applesauce to the cereal mixture and beat well. Fold in the flour mixture just until combined, but don't over mix. Scoop the batter into the prepared muffin tin and sprinkle a little cinnamon sugar on the tops.
Bake in the preheated oven until lightly browned, about 18 to 20 minutes. Remove from the muffin tin and allow to cool about 5 minutes. Serve warm.
