01 - In a medium saucepan, combine oats, milk, maple syrup, cinnamon, vanilla, and salt. Mix thoroughly to incorporate all ingredients evenly.
02 - Place saucepan over medium heat and bring mixture to a gentle simmer, stirring occasionally to prevent sticking and ensure even heating.
03 - Once mixture begins to thicken after approximately 5 minutes, stir in the raisins and distribute them evenly throughout the oats.
04 - Continue cooking for 3–5 minutes, stirring frequently, until oats achieve desired creamy consistency and raisins become plump and tender.
05 - Remove from heat and allow oatmeal to rest for 1–2 minutes to thicken further before serving.
06 - Divide oatmeal evenly between two bowls. Top with chopped nuts and additional maple syrup if desired. Serve immediately while warm.
