This recipe will make lots of chocolate syrup, which you can add to plain milk.
Don’t put the hot syrup in the fridge. It can change the interior temperature and spoil the surrounding food.
If you want hot chocolate, make the chocolate milk in a mug, then heat it in the microwave. [4] X Research source If you want a chocolate milkshake, combine 1 cup (240 milliliters) of milk, ¼ cup (60 milliliters) of the chocolate syrup, and 2 cups (288 grams) of vanilla ice cream in a blender.

Add some ice cubes to make it nice and cold. Store the rest of the chocolate milk powder for later.
Use a blender if you want to create a foamy chocolate milk.
For an extra kick, add in a pinch of ground cinnamon.
You can also use hot water from the tap. It would be best if it’s filtered.
