Combine oats and liquid: In a medium saucepan, combine rolled oats, milk, and salt. Bring to a boil over medium-high heat.
Add pumpkin and spices: Reduce heat to medium-low and stir in pumpkin puree, maple syrup, vanilla extract, pumpkin pie spice, and cinnamon.
Simmer: Cook for 5-7 minutes, stirring frequently, until oats are tender and mixture has thickened to your desired consistency.
Adjust consistency: If oatmeal is too thick, add more milk. If too thin, cook a bit longer while stirring.
Taste and adjust: Remove from heat and taste for sweetness, adding more maple syrup if desired.
Serve: Divide oatmeal between bowls and top with chopped nuts, pumpkin seeds, and chocolate chips if using.
Finish: Drizzle with additional maple syrup and add a dollop of whipped cream or Greek yogurt if desired. Serve immediately while hot.
