Preparation:

Step 1: In a large saucepan over medium heat, combine the whole milk and heavy cream. Stir frequently to heat the mixture without boiling.

Step 2: Add the semi-sweet chocolate chips and cocoa powder to the heated milk mixture. Whisk until the chocolate melts and the mixture becomes smooth and rich.

Step 3: Stir in the sugar to sweeten. Adjust the sugar quantity based on your preference for sweetness.

Step 4: Add vanilla extract and continue stirring to blend all flavors. Reduce the heat to low, and let the hot chocolate simmer for 5-7 minutes.

Step 5: Optional – For a Halloween-inspired color, add a few drops of orange food coloring, stirring until evenly mixed.

Step 6: While the hot chocolate is simmering, prepare the toppings. Spoon whipped cream into a piping bag and pipe ghostly shapes on the surface. Add candy eyeballs for an eerie look, and drizzle with chocolate syrup to create spider webs.

Step 7: Pour the hot chocolate into mugs and top with your Halloween toppings. Add mini marshmallows, sprinkles, and chocolate shavings for an extra festive touch.
