How to Make Marshmallows - Homemade Marshmallows Recipe (without corn syrup)

Learn how to make marshmallows without corn syrup with this easy homemade marshmallows recipe. With just 3 basic ingredients, you can make lots of different flavored marshmallows right from your very own kitchen.

How to Make Marshmallows - without any corn syrup

I first learned how to make marshmallows many years ago. It was just a one time try to make my own marshmallows, and they turned out great. 

And I was so happy I could make my own homemade marshmallows. But then, it stopped there. I never got into making them again as I do not use marshmallows as much until recently when I decided to revisit marshmallow making.

How to Make Marshmallows - My Recipe Notes

Though one might think that marshmallows are hard to make, they are in fact quite easy.  And if you were to look at the ingredients list, they are very minimal with only 3 main ingredients and even those are pretty basic ones that are easy to find:

  • Castor sugar
  • Gelatin (unflavored)
  • Hot water

And my recipe does not use corn syrup so if you are looking for a marshmallows recipe without corn syrup, this is just for you. 

The other optional ingredients are:

  • Flavoring
  • Coloring (optional)

Though these are optional, they do make a difference to the marshmallows especially the flavoring. The gelatin I use in my recipe is the powdered one and its unflavored. And because of this, it sometimes has a pretty strong smell, so the flavoring is quite important. Plain old vanilla is sufficient, but if you want something more fancy, you can use any fruit flavors, or coffee flavor or anything else that suits your liking.

Coloring is optional, but then again, if you are planing on matching your marshmallows with the flavoring you've added to it, tinting your marshmallows in a matching color can make a whole lot of difference too.

  • The process of making the marshmallows starts by preparing the molds. It is normally poured into a large dish and then cut up into small pieces once it has set. Any dish is fine for marshmallows, and I often only use my cake tin. An important point to note in preparing the dish or mold is to make sure it is really well greased and line. I grease my cake tin bottom and sides, line it with parchment paper and then grease it again. And right before pouring my marshmallow into the tin, I dust it with icing sugar - cornflour mix. Making marshmallows can be a really sticky affair so you need to really do this step properly to avoid all the mess.

  • Next is the gelatin. Start by soaking it in half of the hot water. And while waiting for the gelatin to dissolve, the sugar and the remaining water is mixed together and boiled until it reaches a soft ball stage. 
  • Soft ball stage is a test used to check on the readiness of sugar syrup  by pouring a  a few drops of the sugar syrup into a saucer filled with cold water and pushing the syrup with your finger. If the sugar dissolves immediately, the syrup is not ready. Boil it a little longer and test again. At soft ball stage, the syrup can be molded into a very soft ball with your fingers. An easier way to determine the soft ball stage is by using a thermometer. Soft ball stage is when the syrup reaches between 235 to 240 degrees Fahrenheit or  between 112 to 116 degrees Celsius.
  • Once the sugar syurp is ready, it is then carefully poured into the gelatin and stirred until the gelatin is all completely dissolved. 
  • The next step is whipping up the sugar-gelatin solution. The solution is poured into a mixing bowl, and whisked until it becomes thick and foamy. This would take a good 12 to 15 minutes. The  marshmallow is done when it has increased in volume and has reached a soft peak stage. The peaks will be very soft and they don't stand stiff.

  • To set the marshmallow, it is then poured into the prepared dish and left in a cool place overnight to set completely.

  • To cut the marshmallow, again, it is very important to grease the knife well. Turn the marshmallows out of the dish onto a well sugared (I use a mix of icing sugar and corn flour) work space, sprinkle more icing sugar on top and cut it into desired size.

  • If you had greased your dish well, it should be an easy process. Toss the cut marshmallows into more icing sugar - cornflour mix until they are all well coated.

Easy homemade marshmallows recipe without corn syrup.


Prep Time: 40 minutes
Cook time: 10 Minutes
Yield: 6 inches square marshmallow block
Keyword: How to Make Marshmallows
Category: Dessert


  • 200 g castor sugar
  • 1 tbsp gelatin (unflavored)
  • ½ cup hot water
  • ¼ vanilla essence
  • Coloring (optional)


  • 50 g icing sugar
  • 15 g corn flour


  1. Prepare a 6 inches square tin to pour the marshmallow in. Grease the tin, line with parchment paper and grease again. Dust with a little icing sugar and set a side.
  2. Mix gelatin with half of the hot water and leave aside for the gelatin to dissolve.
  3. In another saucepan, mix sugar with the remaining half of the water (¼ cup) and cook over low heat until sugar has dissolved.
  4. Continue to cook until the sugar syrup reaches the soft ball stage* or until it reaches between 235 to 240 degrees Fahrenheit or between 112 to 116 degrees Celsius.
  5. Add in the gelatin mix and stir until gelatin is all dissolved. Remove from heat and let it cool down slightly for about 2 minutes.
  6. Pour the sugar-gelatin syrup into a mixing bowl and whisk on low speed for 3 minutes before increasing the speed to high for another 10 minutes. Mixture should be white and glossy but not too stiff. Add vanilla essence and continue to whisk for another minute. If you wish to color your marshmallows, add the coloring at this stage.
  7. Pour the marshmallow mix into the prepared tin and level the top with a spatula.
  8. Leave the marshmallow to set for at least 8 hours or overnight.
  9. Carefully peel off the parchment lining and dust the uncut marshmallow block with the icing sugar - cornflour mix (can use the one mixed for tossing). Grease your knife and cut the marshmallow block into smaller pieces as you wish.
  10. This recipe makes a 6 inches square marshmallow block with a height of about 1.3 inches.

  11. * Soft ball stage is when the sugar syrup has thickened quite considerable. To test for the soft ball stage, fill a small saucer with cold water and pour a small amount of the sugar syrup into the water. Push the syrup with your finger. If it forms into a soft ball when pushed, it has reached the soft ball stage.
