1. In a medium saucepan, combine rolled oats, milk, water, salt, and cinnamon (if using). Bring to a gentle boil over medium-high heat.

2. Reduce heat to low and simmer, stirring occasionally, for 5-7 minutes until oats are tender and creamy. Adjust liquid as needed.

3. While oats cook, slice bananas into 1/2-inch rounds.

4. In a non-stick skillet, melt butter over medium heat. Add banana slices in a single layer and drizzle with 1 tablespoon maple syrup. Cook for 2-3 minutes per side until golden brown and caramelized. Remove from heat.

5. Remove cooked oatmeal from heat. Stir in remaining 1-2 tablespoons maple syrup to taste.

6. Divide oatmeal into serving bowls. Top with caramelized banana slices, fresh blueberries, and a dollop or drizzle of peanut butter.

7. Serve immediately.
