Gather all ingredients.

In a medium saucepan, combine rolled oats and milk over medium heat. Stir occasionally until simmering, then cook for about 5 minutes until creamy.

While the oats are cooking, mash the ripe bananas in a bowl until smooth.

Fold the mashed bananas into the cooked oats along with honey and cinnamon until well combined.

Serve in bowls and top with additional banana slices, nuts, or yogurt if desired.
