For extra flavor, consider adding 2 teaspoons of pure chocolate extract and/or 1 teaspoon of vanilla extract. [5] X Research source
Your frozen hot chocolate won’t be completely smooth like a milkshake or smoothie. It will have a slight grainy texture to it.
If you cannot find any, and only have hot chocolate mix on hand, use 2 teaspoons of hot chocolate mix and 1½ tablespoons (23 grams) of sugar instead.
If the mixture starts to turn solid, place the saucepan on the burner, and turn the heat to low. Continue stirring it until it melts again. [9] X Research source
If the mixture is still warm, place it into the freezer for a few minutes until it turns cold. Do not let it freeze, however.
If your blender isn’t very strong, use crushed ice instead.
