Hi Bold Bakers!
The only thing more nostalgic than an ice cream sundae is an ice cream sundae that tastes like a S’more! This recipe for Homemade Marshmallow Sauce for a S’more Ice Cream Sundae is the perfect marriage of my two favorite summer time treats. Now you won’t need to be sitting around a campfire to be eating a S’more! Instead, get ready to dig into my rich chocolate and graham cracker ice cream — smothered in the fluffiest, most pour-able marshmallow sauce you’ve ever had.
What is Marshmallow Sauce?
You might be wondering how to make marshmallow sauce, but you’re probably also wondering what it is. Marshmallow sauce is, honestly, what I would describe as a magic sauce. It’s made of things that you might not expect and has a texture and flavor like anything you might have ever tried.
Similar to my marshmallow fluff, my Homemade Marshmallow Sauce is as light as air, extremely sticky, ooey and gooey just like a marshmallow when it melts. The difference between marshmallow fluff and sauce is that it is pour-able. This is what makes it ideal for completing my S’more Ice Cream Sundae. Its also perfect for pouring over all kinds of desserts, pies, fruits… There’s really nothing that cant be improved by Marshmallow Sauce!

What is the Soft Ball Stage?
The trick to making my Homemade Marshmallow sauce is making the beginning of homemade candy, but instead of turning this sweet syrup into candy it gets whipped to white fluffy perfection.
There are two parts to this sauce, and one part is just water with a tiny bit of gelatin. This is what allows the Marshmallow Sauce to hold onto its lightness. The other part of the sauce is a candy-like syrup or water, sugar corn syrup, and a bit of salt. The light corn syrup is what makes this sauce a sauce, thick and pour-able, while the sugar and dash of salt obviously give the sauce its sweet marshmallow flavor.
While the gelatin and water “bloom,” creating a jell-o like texture, the other ingredients simmer together to form a sweet and thick clear syrup. It’s super important to follow my exact instructions on how to treat this syrup, because candy making can be tricky. The secret to this is to leave the ingredients to simmer undisturbed until they reach exactly 240°F (480°C), which is what is called “soft ball stage” in candy making terms (many candy thermometers will have this stage marked). After you’ve reached this stage the rest is super simple, I just pour the hot syrup over the gelatin mixture and whip.
After 10-12 minutes, what you’ve got is on crazy tasty Homemade Marshmallow Sauce!
How to Make 2 Ingredient Ice Cream
My S’more Ice Cream Sunday starts with the ice cream. This ice cream represents the chocolate and graham cracker part of a S’more. It is rich, chocolatey, and loaded with crunchy graham chunks which means it’s both creamy and smooth while being full of texture.
Just like all of my other ice cream recipes, this one starts with a base of my famous 2 Ingredient Ice Cream. All you need to make the base is heavy whipping cream and sweetened condensed milk. After a quick whip up with a hand or stand mixer, the cream and condensed milk transform into the most lovely ice cream — the perfect blank canvas for any flavor of ice cream. To turn my 2 ingredient ice cream base into chocolate and graham ice cream, I simply add melted chocolate and crushed graham crackers.
Instantly, you’re halfway to a S’more ice cream sundae! All you need to do now is freeze the ice cream for a minimum of 6 hours or preferably overnight.
How to Make an Ice Cream Sundae
After I make my homemade chocolate and graham ice cream, and I whip up my magic Marshmallow Sauce, the only thing left to do is put the two together! To build this S’more Ice Cream Sundae I suggest going big and bold! This means 3 giant scoops of ice cream and a generous pour of marshmallow sauce. I can’t even describe to you how heavenly this sundae is. If you’ve never tried a S’more Ice Cream Sundae, then I’m telling you: today is the day!
