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!

What is marshmallow sauce made of?

Marshmallow sauce is made with sugar, cornstarch, and salt, while frosting typically contains butter, powdered sugar, and milk or cream. Marshmallow sauce has a smoother consistency than frosting, and it's also less sweet. It's perfect for topping sundaes, cakes, or other desserts.

Can you freeze marshmallows in ice cream?

Once churned, toast the remaining marshmallows and mix them into the churned ice cream, then pour into a container and freeze.

Can melted marshmallows be substituted for marshmallow cream?

They are not the same. Marshmallow cream is made without gelatin and will not firm up over time. Marshmallows that have been melted down, on the other hand, will firm back up unless you add something to them to help keep them more fluid (like adding butter to make rice krispie treats).

Is marshmallow fluff the same as marshmallow topping?

Technically speaking you can use marshmallows in place of marshmallow fluff but the texture will be considerably different. Marshmallows do not contain eggs or egg whites, as marshmallow fluff does. In addition, they contain cornstarch, which can alter the texture of your finished candy.
