In a medium saucepan, combine 2 cups of whole milk and 1 cup of heavy cream. Heat over medium heat, stirring occasionally, until the mixture begins to steam, about 5 minutes, without allowing it to boil.

Reduce the heat to low and add 1 cup of white chocolate chips. Stir continuously until the chocolate is fully melted and the mixture is smooth, about 3 minutes.

Stir in 1 teaspoon of vanilla extract and 1/4 teaspoon of salt, mixing well to combine and balance the flavors.

Taste the hot chocolate and adjust sweetness if desired by adding more white chocolate chips or a teaspoon of sugar, then stir until dissolved.

Pour the hot chocolate evenly into heatproof mugs.

Top each mug with whipped cream if desired, and garnish with a sprinkle of cinnamon or chocolate shavings.

Serve immediately while hot and enjoy the creamy, comforting drink.

To store leftovers, let the drink cool, then refrigerate in an airtight container for up to two days. Reheat gently over low heat before serving.
