Ah, the humble marshmallow. Whether it’s roasted over a campfire, squeezed into a s’more, or just eaten straight from the bag, marshmallows are a beloved treat.

Can You Melt Marshmallows in the Microwave?

Have you ever tried melting marshmallows in the microwave? If not, you might be missing out on a game-changing baking trick. The microwave offers a quick and easy solution for melting marshmallows, compared to the laborious process of slowly heating them over a stove or open flame.

Plus, microwaving gives the marshmallows a gooey texture that is perfect for indulgent treats like s’mores dip or rice Krispie treats. However, it’s important to keep an eye on your marshmallows as they melt. It’s easy to turn them into a sticky, burnt mess if you’re not paying close attention to the process.

For best results, microwave in short bursts, add a couple of tablespoons of water to the marshmallows and stir frequently until they reach your desired consistency. It might take a little practice to get the perfect melt, but once you do, you’ll be whipping up sweet treats in the microwave in no time.

  2. Add 2 -3 tablespoons of water.

  4. Once the marshmallows are smooth and melted, remove them from the microwave and use them immediately.

Safety Tips When Melting Marshmallows in the Microwave

If you want to melt marshmallows in the microwave, it’s important to keep a few safety tips in mind.

DO Use a Microwave-Safe Bowl

When melting marshmallows in the microwave, it’s important to use a microwave-safe bowl. Glass or ceramic bowls are always a good choice. If you’re not sure if your bowl is microwave-safe, play it safe and use one that you know for sure is.

DO Microwave in Short Bursts

To prevent your marshmallows from overheating and burning, be sure to microwave them in short intervals. This will give you more control over the melting process and allow you to adjust the heat as necessary.

DO Add Water

If you’re worried about your marshmallows getting burnt, consider adding a couple of tablespoons of water to the bowl along with your marshmallows. This small addition can help regulate the temperature and ensure that your marshmallows melt just right.

DON’T Overfill The Bowl

When melting marshmallows in the microwave, it’s important not to overfill the bowl. You should leave enough room in the bowl for the marshmallows to expand as they melt. If you want to melt a lot of marshmallows in the microwave, it’s best to do so in multiple batches.

Pros and Cons of Melting Marshmallows in the Microwave

There are both pros and cons to melting marshmallows in the microwave. Let’s take a look at some of the key benefits and drawbacks of this approach:


It’s Fast

One of the main advantages of melting marshmallows in the microwave is that it’s fast. If you’re in a hurry or just don’t feel like waiting, microwaving your marshmallows is a quick and easy solution.

Less Cleanup

Another benefit of melting marshmallows in the microwave is that it tends to produce less mess than other approaches. You don’t have to worry about cleaning up sticky remains or scorched pots and pans.


It’s Easy to Overdo It

The first con of melting marshmallows in the microwave is that it’s easy to overcook them. If you’re not careful, it’s easy to go from perfectly melted to burnt in just a matter of seconds. But don’t worry, avoiding this problem is as simple as microwaving in short increments and stirring frequently.

You Can’t Melt Too Many At Once

Another downside of melting marshmallows in the microwave is that you can only melt a certain amount at once. If your recipe calls for a lot of marshmallows, you’ll have to melt them in several batches.

How to Store Melted Marshmallows

We’ve all been there – you made a warm and gooey batch of melty, toasty marshmallows, but now you find yourself with leftovers. Luckily, there are easy and successful options for storing these treats for later enjoyment. The refrigerator is a great choice for shorter-term storage.

To keep your marshmallows fresh in the refrigerator, simply place them in an airtight container or sealable plastic bag. Ideally, try to use your marshmallows within 2 weeks for the best flavor and texture.

If you want to save them for even longer periods, popping them into the freezer can extend their shelf life to three months. Simply transfer them to a freezer-safe Ziploc bag or container, and seal them tightly before putting them into the freezer.

When you’re ready to enjoy your marshmallows, remove them from the freezer and let them thaw in the fridge overnight. I don’t recommend thawing them in the microwave, as this can cause them to lose their texture.

Other Methods for Melting Marshmallows

There are a number of different methods for melting marshmallows, beyond just the microwave. Here are some common alternatives to explore:

1. The Double Boiler Method

This approach involves placing a pot of water over low heat and then placing your marshmallows in a bowl that will sit on top of the pot. The heat from the water will slowly melt your marshmallows, letting you control the temperature and avoid burning them.

2. The Oven Method

If you need to melt a large batch of marshmallows at once, the oven is another popular option. Simply preheat your oven to 200-250 degrees F and spread your marshmallows in a non-stick baking dish. Let them melt in the oven for 5-10 minutes until you have a gooey marshmallow masterpiece.

3. The Campfire Method

Finally, if you’re camping or taking a trip to the great outdoors, you can melt your marshmallows over an open flame. First, you need to place marshmallows on a skewer or roasting stick, then hold them over a fire. You can tell when they’re ready if the outside is golden brown and crispy.
