In a large bowl, sift together the cocoa powder, powdered milk, and cornstarch (if using) to remove any lumps.
Add the sugar, salt, and vanilla powder (if using) to the cocoa mixture. Whisk together until well combined.
Store the hot cocoa mix in an airtight container.
To make a cup of hot cocoa, heat up a mug of milk or water. Stir in 2-3 tablespoons of the cocoa mix, or adjust to taste. Mix well until fully dissolved.
Serve hot with your favorite toppings like whipped cream, marshmallows, or a sprinkle of cinnamon.
Notes
• Sift the cocoa powder and powdered milk to avoid lumps in your mix.
• Store the cocoa mix in an airtight container to keep it fresh and dry.
• For a richer taste, add a pinch of cinnamon or nutmeg to the mix.
• Use hot water or warm milk to dissolve the mix for a creamier texture.
• Adjust the amount of mix to your liking for a stronger or milder chocolate flavor.
