Can you Microwave Milk for Hot Chocolate? (Facts Revealed)

Here’s a fun fact for you, did you know that 31st January is celebrated as “National hot chocolate day”?

With a drink so popular that it has its own dedicated day there has to be some kind of magic behind it. Of course, part of that magic comes from knowing how to mix ingredients like milk, cocoa powder, chocolate, and brown sugar to make a cup perfectly. 

Traditionally hot chocolate was always prepared on the stove, stirring in each ingredient one at a time. But who’s got the time to do that now? Enter the microwave, the king of convenience. 

But can it make hot chocolate taste the same way? Because a lot of people have this misconception that microwaving milk will either make it boil over or burn.

Look no further if you are searching for the answer to this riddle. Here I’ll clear up all your kitchen conundrums related to microwaving milk for making hot chocolate.

Can you microwave Milk for hot chocolate?

Yes, you can heat up milk for hot chocolate in a microwave. In fact, heating milk in a microwave is a better idea than doing it on a stovetop because you won’t warm up the entire kitchen in doing so. 

You can safely microwave your milk high enough so it’s steaming hot, or low enough just to take the chill out. And if you follow the tips mentioned in this article correctly you won’t have to worry about your milk curdling or exploding and making a mess in the microwave.

How to microwave Milk for hot chocolate?

The best way to microwave milk for hot chocolate is a pretty simple and straightforward process and it doesn’t require any fancy gadgets. Here is the list of things that you’ll need (most of them are already present in your kitchen):

  • Milk (Dairy or plant-based depending on your preference)
  • Microwave-safe mug or any other container
  • Wooden spoon
  • Cooking thermometer
  1. Get your microwave-safe mug/container. Make sure that it’s big enough so that 2/3rd of it remains empty after being filled with milk.
  2. Pour in your milk. Bonus tip: Add a wooden spoon or a wooden chopstick to prevent the milk from bubbling over the sides.
  3. On medium-high heat, microwave the milk in 15-second intervals.
  4. Stir in between each interval. This will distribute the heat evenly throughout the milk and prevent a skin from forming on top.
  5. Keep checking the temperature using the thermometer until the milk has reached the desired temperature. 70-80 degrees Fahrenheit for warm, 110-160 degrees Fahrenheit for piping hot milk.
  6. Once your milk has heated up to your liking, carefully remove it from the microwave using oven mitts and use as per your recipe.

How Long to Microwave Milk for Hot Chocolate?

Microwave milk for hot chocolate for between 1-2 minutes, stirring in between 15-second intervals. 

Doing this not only distributes the heat evenly throughout the milk but also prevents the milk from becoming overheated and when you use a food thermometer it will give a more correct reading.

How hot to heat milk for hot chocolate?

It’s all a matter of preference about how hot you like your hot chocolate to be. 

140 degrees Fahrenheit should be fine for hot and if you further wish to take it up a notch then 160 degrees Fahrenheit should be enough for extra hot. 

Heat milk any further and you run the risk of scalding milk, after which it might develop a skin on top that will not dissolve but separate into chunks when you whisk it and you will see it floating around in your finished hot chocolate.

How do I know if I’ve overheated the milk?

The main reason we microwave milk in 15-second intervals is to stop it from overheating in the first place.

Here are two things that may indicate you’ve gone too far in heating your milk.

  1. It develops a film on the surface. This is the most common sign that milk has been overheated. If you try to mix this film in, it won’t dissolve but rather remains floating around in clumps that will give your hot chocolate an unappealing look.
  2. Overheat milk in a metal saucepan and you will notice it starts to stick to the bottom of the pan and develop a burnt taste as well. While this sticking may not be as apparent in the microwave but you will notice a slight change in the texture, which will affect the final texture of the hot chocolate.


How can I microwave milk without curdling?

If you heat your milk on too high heat, or too fast it can cause the casein in milk to clump together and curdle.

Microwaves cause uneven heating of foods, this is why it is recommended that you stop the microwave after every 15 seconds and gently stir.

However, sometimes you might be microwaving on the lowest heat setting and your milk might still curdle. That usually happens if you have kept a too small quantity of milk in the microwave.

To prevent this from happening keep a small glass of water along with your milk in the microwave to absorb some of the microwave’s power thus preventing the milk from curdling.

Why did milk explode in the microwave?

That probably happened because you didn’t stir it enough during heating.

Unless you keep stirring your milk regularly, milk fats form a layer on the surface and trap the heat inside.

It explodes (or violently bubbles up) when the heat can’t be contained any longer. To avoid this simply give it a quick stir in between heating.

Can you use milk instead of water for hot chocolate?

Sure it all depends on your personal preferences. 

Some people choose low-fat or even plant-based milk for their hot chocolates. Water can be used instead of milk too. However, be mindful that the creaminess will vary with the fat content though.

  • For a richer take on hot chocolate, you can substitute 1/4th of the milk quantity with cream.
  • Whole milk is generally the preferred option for many to get the perfect combo of texture and creaminess
  • Substituting water may reduce the richness but it will bring out the deep pure chocolatey flavors.

Can you make ahead and store hot chocolate?

I would recommend making hot chocolate the day you plan to drink it. By making it ahead you might miss out on the richness and freshness of the flavors.

However, if you are strapped for time, I suggest you measure and mix all the dry ingredients and keep them in an air-tight jar. Finely chop the chocolate  (so that it’ll melt easier) and keep that refrigerated separately in a jar as well. 

So the next time the craving for a hot cup of chocolate strikes all you have to do is microwave your milk and mix in the rest of the ingredients.

BONUS TIP: Pre-made hot chocolate mix makes a great gift to give your loved ones for Christmas and other occasions.

Is hot chocolate healthier with milk or water?

Hot chocolate is healthier with milk because it has more calcium and vitamin D. Water does not have these nutrients. However, if you have certain conditions, such as lactose intolerance, you may need to avoid dairy products. In that case, using water with chocolate milk is healthier.
