Why Bother Making Homemade Marshmallows?

Homemade marshmallows are so much better than store-bought. There is no comparison to the difference in texture, shape and flavor! When you make them homemade you’re able to make different sizes, flavors and shapes.

Another bonus is when marshmallows are stored properly in an air-tight container they last a long time! They’re also great for making s’mores and melt nicely. We like to cut them the size of a graham cracker for the perfect s’more. There is also something fun about making your own marshmallows. You’ll want to eat them all up!

What are marshmallows?

Marshmallows are a type of confectionery that is made from sugar, water and gelatin, and syrup that are whipped together to a solid-but-soft consistency. They are a fluffy dessert on their own and wonderful paired with hot chocolate or when making s’mores.

The first marshmallows were made as early as 2000 BC. Back then, this sugary treat was served to royalty and to honor the gods. Today, they’re a candy we can all enjoy.

You can find all of these ingredients at the grocery store.

Full recipe and measurements below in the recipe card.

  • Unflavored Gelatin – We use Knox Original Gelatin for this recipe.
  • Light Corn Syrup – Corn syrup is a food syrup made from the starch of corn and contains varying amounts of sugars glucose, maltose, and higher oligosaccharides. We use light corn syrup to make these fluffy marshmallows. We don’t recommend substituting the corn syrup as this recipe works perfectly the way it is.
  • Granulated Sugar – White sugar is perfect for this recipe.
  • Vanilla Extract – Use pure vanilla extract. You can also use other flavors, like lavender or lemon too.
  • Salt – This enhances the flavor and ingredients in the marshamllows.
  • Water 
  • Confectioners’ Sugar – we use powdered sugar to help the marshmallows form sticking to the sides of the pan and hands.
Ingredients for a marshmallow recipe. Water, corn syrup, sugar, gelatin, vanilla extract.

Step by Step Directions

Prepare a 6 x 6 baking pan by rubbing a little vegetable oil on the sides and bottom of the pan. You can also use nonstick cooking spray.

Sift a good amount of powdered sugar all over the bottom and sides until fully coated, at least 1/8th of an inch. This will give the pan a coating so the marshmallows won’t stick.

Measure out the ingredients so you’re prepared. Use a kitchen scale to get the most accurate measurements. This one is $10 and super easy to use.

In a medium saucepan attached with a sugar thermometer, add water sugar and light corn syrup. 

Turn it to medium heat and stir well while bringing it to a boil. 

Preparing a baking dish with thick powdered sugar for marshmallows.

This next step is crucial for the success of this recipe. Bring the hot sugar mixture to 240 to 250 degrees which is between soft ball and frim ball on the candy thermometer. 

Watch very carefully so it’s exactly 240-250 degrees. Once it reaches 240-250 turn stove to a very low simmer while you mix the gelatine.

Prepare the gelatin by combining it and 1/2 of the water in a small bowl. Whisk with a fork until frothy and smooth.

Add it into the bowl of your stand mixer with a whisk attachment and continue whisking so it doesn’t harden or clump up.

Carefully add in the very hot sugar mix into the mixer while it’s whisking on medium speed.

Beat on high for 10 minutes until stiff peaks form and the mixture has a thick and fluffy texture.

Add in the extract and the salt. If you want to color, add in the food coloring too. Just 5 drops will do the trick. 

Pour the mix into the prepared baking pan. Add sprinkles over the top if you want! 

Leave them to sit uncovered for 6-8 hours or over night.

Pouring gelatin into a small bowl

To remove them from the pan, use a little vegetable oil on a knife and sprinkle powdered sugar over it. Cut around the edge of the baking dish. 

Then, add powdered sugar to your clean hands and remove using your fingers. They’re pretty forgiving and bendable once they set, so don’t worry about being rough getting them out of the pan.

Set them on a cutting board sprinkled with powdered sugar. Cut lengthwise three times and then make 3-4 squares from each. You can make these as large or as small as you want!

Every time you make a cut into the marshmallow, roll that side in a dusting if powdered sugar so it won’t stick.

Marshmallows with Sprinkles

If you want to add sprinkles to this marshmallow recipe, add them right after you pour in the mixture into the prepared baking dish. This is when they are gooey and before it sets. 

Add sprinkles over the top, gently pressing down on them, and then let them sit for 6-8 hours or overnight.

Marshmallow Recipe Variations

Colorful Marshmallows – Add food coloring to the marshmallow mixture to make fun colors.

Different Flavors – Use unique extracts to make fun flavors. There are so many options when choosing an extract. Some of our favorites are rose, lavender, lemon, peach, coconut, and banana. Add the flavor to the sugar syrup.

How to Store Marshmallows

The best way to store marshmallows is in an airtight container or a sealed ziplock bag. The goal is to keep them fresh as they dry out easily when left in the open. Check out this complete guide to storing marshmallows.

Frequently Asked Questions

Why did my marshmallow not set?

This is why the candy thermometer is so important when working with hot sugar and candy.

The temperature of the sugar has to be 240-250 degrees if it’s anything less they will not set, and if it’s anything more you will have a very sticky, hard, dense marshmallow.

How Long Do Homemade Marshmallows Last?

When stored correctly, they can last for up to three weeks. 

The biggest thing you need to look out for is moisture and humidity. Keep your marshmallows in an airtight container. 

You should also keep them in a cooler place. Since they’re made of sugar, exposure to heat can cause them to melt or deteriorate. 

If you’ve mixed anything into them or dipped them in chocolate, then their shelf life will be slightly shorter.

What are marshmallows made of?

For the marshmallow recipe we use gelatin, corn syrup, sugar, salt, water and vanilla extract.

Can You Freeze Marshmallows

If you want them to last longer, throw them in the freezer. They will last for up to three or four months. This is a great strategy if you’re making several batches of holiday marshmallows as you prepare for the holiday season.

Does Homemade Marshmallow Need to Be Refrigerated?

Your marshmallows are shelf-stable, so they don’t need to be refrigerated. As long as you keep them in a cool, dry place, they will stay fresh and last. 

However, if you live in a tropical or humid place, it’s better to keep them in your fridge. This will prevent them from melting and sticking together.

How Do You Cut a Marshmallow?

Several online guides advise using scissors. While these will work, they smash them, and you don’t end up with perfect squares.

50/50 Mixture

You can use confectioner’s sugar or create a 50/50 mix of cornstarch and confectioner’s sugar. Then dust your work surface, lay the marshmallow sheet down, and dust the top.

Coat a sharp knife with a thin layer of oil. Carefully cut the marshmallow sheet with the knife. If you see the knife starting to stick, coat it with more oil.

Toss the cut pieces in the 50/50 mixture and shake off the excess. This will prevent your marshmallow pieces from sticking. 

How do you unstick marshmallows?

To unstick marshmallows use powdered sugar. Sprinkle it over the sticky areas and it will instantly unstick the marshmallows.

Are Marshmallows Gluten-Free?

Most marshmallows are gluten-free. There are only two times when this isn’t the case. If they’re manufactured in a factory that has gluten products, and there’s cross-contamination. The other thing to watch out for is ingredients that include wheat starch. 

If you’re making your own, you can easily avoid these two situations. This means your marshmallows are gluten-free!

Are Marshmallows Vegan?

Most marshmallows are not vegan. This is because one of the main ingredients is gelatin. This gelling agent is made from the collagen in animal skin and bones. 

The good news is that you can make your homemade marshmallows vegan friendly. You’ll need to replace the gelatin with a vegan-friendly gelling agent, such as carrageenan or agar-agar. These are both derived from seaweed. 

What makes a marshmallow fluffy?

The whipping process is what makes them fluffy! Air is whipped into the sugar mixture and allows it to become a nice fluffy texture. The gelatin helps that whipped texture set and when they are ready it results in a nice fluffy marshmallow!

    These were so fun to make. My children loved the whole process. I subbed out half the corn syrup for local honey and the flavour was stunning. Thank you for posting.
