Homemade Marshmallow Sauce
You’ll love having a jar of this Homemade Marshmallow Sauce in your cupboard! So simple to make and great for so many uses, from ice cream sundaes to fluffernutter sandwiches! Just five simple ingredients and naturally gluten-free.
Hey guys! Once again, I’m dashing this one off in a hurry because my kiddos are about to blast through the front door at any moment and all hell’s gonna break loose!
This is a really useful recipe that you’ll love having in your back pocket! It whips up really fast with only 5 ingredients, and it’s sooooo fluffy, sweet, and vanilla-y. I love it on everything from ice cream sundaes to peanut butter sandwiches.
It’s a little thinner and more pourable than marshmallow fluff, but I think if you cut the water down a bit you’d have a dead ringer on your hands. Personally, I think the sauce consistency is more versatile.
I LOVE this with chocolate ice cream. It really is my favorite of all ice cream toppings. You could also swirl it into your homemade ice cream recipes as they come out of the machine! But there are tons more uses, you’ll discover when you have a jar of this in your cupboard or fridge!
I’m sorry to be in such a rush but they just busted down the door and they’re dying to tell me all about their End-of-School-Year Party!

Homemade Marshmallow Sauce
Ingredients
- 1 cup (250 ml) water,, divided
- 1 teaspoon unflavored powdered gelatin
- 1 1/2 cup (300 g) granulated sugar

- Stir in the vanilla bean paste and transfer to a large mason jar.
Hi and thank you for this amazing recipe! This should be okay to can (seal in mason jar for pantry storage) using either the water bath or the pressure canning method, correct? Thanks for your imput
Hey there! I’m so sorry but I haven’t tried that so I can’t say for sure. If you give it a go will you let me know how it works out?
Thank you! Thank you! Thank you! I have a severe egg allergy and can’t use Marshmallow Fluff. So excited to see this recipe 😍
I have no idea why I could not add the fifth most important star. But trust me it’s there! Maybe it is there now 😅
Hi, what does this freeze like? I’m thinking of swirling it in some frozen treats
It freezes beautifully! I’ve used it to make chocolate marshmallow ice cream and it was a big success. It stays gooey. You can take a peek here: https://bakingamoment.com/chocolate-marshmallow-rice-krispie-treat-ice-cream/.
Hi I was wondering how long you have to mix it? Mine is not turning white.
It usually takes around 5-10 minutes. Good luck!
Hi! I’m wondering how long this can stay good for in a closed container? Can it stay at room temperature? Thanks
Hey Rebecca! It will start to separate after a few days, regardless of whether or not you refrigerate it I’m afraid.
Do you use a hand mixer for this or a stand mixer? I have a 6qt KitchenAid and I am worried that there isn’t enough liquid to mix in the mixer or would I need to double it to get enough volume to really reach the whisk. Has anyone done in a stand mixer?
I usually use a stand mixer but mine is not quite as large as yours. I have a KitchenAid Artisan Tilt-Head with a 5-quart bowl. Once the syrup goes in, the mixture whips up to nearly fill the bowl. Hopefully this is helpful info!
I live in Australia and can’t source corn syrup in my local area, at a reasonable price. What would be a suitable substitute for corn syrup?
Hey Janelle! Here’s an article that will hopefully be helpful to you: https://www.thespruceeats.com/light-corn-syrup-substitute-1388889. Good luck!
Do you know how long this keeps and does it separate???
Hi Lindsay! It’s best to keep it in the fridge to avoid separating. It should last a month or so. Enjoy!
Wow! I have never seen so many positive comments in one place! This is going in my fridge tomorrow morning. I love your glass mixing bowl. Could you tell me where you purchased it, please?
Hey Sharon! I’m so glad you’re going to give this recipe a try. I hope you love it as much as I do! Here’s an Amazon affiliate sales link to the bowl I have on my mixer: https://amzn.to/2AcSGfF. Thanks!
I’m having an ice cream sundae bar for my son’s 8th birthday, just wondering what the shelf life for this is outside of the fridge? It looks perfect!
Hey Adam! Thanks for the great question. This keeps well at room temperature for around 12 hours or so. After that, it starts to separate. You can stir it vigorously to bring it back together, but I prefer to just keep it in the fridge. It lasts in the fridge for at least a week without any problem. Happy birthday to your son!
So many awesome ideas for this!
I never even thought to make my own, but it looks so darn good!
My kids would love this!
I want to make it as fast as I can. ^^ I you dont mind can I ask something? Usually I make Marshmallow (not marshmallow sauce), and that recipe also using gelatin, and sometime in my bored day I put homemade marshmallow in jar and put them in fridge. But, that make them set ini jar. So my question, is this recipe marshmallow syrup when you put them in to fridge they didn’t set. Thanks ^^
Yes, that’s right Jhosi! It is a sauce and although it does become thicker as it cools, it remains thin like a sauce. It does not set up as firm as the candy does. Hope that’s helpful!
I can think of SO many things to put this on!
What a great addition to a hot fudge sundae!!!
This will be a huge hit in my house!
