01 - Combine sugar and water in a small saucepan. Heat over medium heat, swirling occasionally until mixture turns golden brown (approximately 3-4 minutes). Remove from heat and carefully whisk in heavy cream, vanilla extract, and sea salt until smooth. Set aside.
02 - In a separate saucepan, combine milk, ground cinnamon, and ground nutmeg. Warm over medium heat until steaming, taking care not to boil. Stir occasionally to ensure even heating and spice distribution.
03 - Divide the prepared caramel syrup evenly between two heat-resistant mugs. Pour the hot spiced milk over the caramel, stirring gently to incorporate the flavors. Ensure caramel is fully dissolved into the milk.
04 - Top each mug with a generous layer of whipped cream. Drizzle additional caramel sauce over the whipped cream and dust with extra cinnamon if desired. Serve immediately while hot for optimal flavor and texture.
