Start by gathering all your ingredients. This streamlines the process and makes cooking more enjoyable. Measure out the sea salt, vanilla, espresso powder, milk, caramel sauce, and chocolate. This ensures you have everything on hand.

Step 2: Heat the Milk

In a medium saucepan, pour in the 4 cups of whole milk. Place it over medium heat and stir occasionally. You want the milk to warm gently without boiling. This step usually takes about 5 minutes. The aroma of the milk warming up starts creating a cozy atmosphere in your kitchen.

Step 3: Add the Chocolate and Caramel

Once the milk is warm, add the 1 cup of finely chopped semi-sweet chocolate. Stir continually until the chocolate melts completely. Then add the 3 tablespoons of caramel sauce. Mix until everything combines smoothly, creating a rich chocolate caramel mixture. This should take about another 3 to 4 minutes.

Step 4: Incorporate the Flavor Enhancers

Stir in the ¼ teaspoon of sea salt, 1 teaspoon of vanilla extract, and ½ teaspoon of instant espresso powder. Each addition adds depth, sweetening the drink while enhancing the flavor profile. Allow it to simmer for about a minute, stirring constantly to combine.

Step 5: Serve and Enjoy

Once everything is well-mixed and you have a velvety consistency, pour the hot chocolate into mugs. Feel free to garnish with whipped cream, a drizzle of caramel, or some fluffy marshmallows. Sip slowly, savoring every warm, comforting gulp.
