In a medium saucepan set over medium heat, bring milk to a boil, watching carefully so that it doesn't boil over. Stir in oats, reduce heat to a simmer, and cook for 1 to 2 minutes, stirring occasionally. Remove from heat and cover for a few minutes. Stir in mashed banana, peanut butter, cinnamon, vanilla, and salt. Stir in honey, to taste, if desired. Top with sliced bananas, chopped peanuts, and additional cinnamon before serving.
