Homemade Marshmallow Sauce Ice Cream Topping Recipe

Homemade marshmallow sauce is a delicious topping for ice cream.  Marshmallow sauce is easy and inexpensive to make, and it tastes so much better than store the store bought variety.

I'm on an ice-cream-kick, if you couldn't tell.  Have you ever made homemade marshmallow cream sauce ice cream topping?  

It's way less messy than making actual homemade marshmallows (I promise), and it's SO GOOD.  Especially when you pair it with homemade hot fudge sauce.  Heaven!  I had this combination of devil's food cake, vanilla ice cream, hot fudge, and marshmallow sauce (known as a Vassar Devil) for the first time my freshman year at Vassar.  It's memorably delicious!

Homemade marshmallow sauce isn't quite as thick as the store-bought variety, which I think is actually better, because you can actually pour it on your ice cream sundae.  I got this recipe from my pastry-chef mother, and it's absolutely amazing.

Ingredients for homemade marshmallow sauce on a wooden cutting board.

Homemade Marshmallow Sauce Ingredients:

  • 1 cup water, divided in half
  • 1 teaspoon unflavored gelatin
  • 1 1/2 cups sugar
  • 1 cup light corn syrup
  • pinch salt
  • 1 teaspoon vanilla

1) Put half of the water in a large mixing bowl.  If you're using a stand mixer like a Kitchenaid mixer, put it directly in the mixer bowl.  Rain the teaspoon of unflavored gelatin evenly over the surface of the water (see the video for a visual of what I mean) and set aside.

2) Put the remaining water, sugar, corn syrup, and salt in a small saucepan and cook over medium-high heat.  Don't stir it, just give it the occasional swirl, if necessary.  Cook until the temperature reads 240 degrees Fahrenheit (soft ball stage) on a candy thermometer.

3) Pour the hot mixture into the bowl with the gelatin mixture.  Whip on a low speed for two minutes, then add vanilla, and whip on high speed for several minutes, until the mixture is thick, white, and fluffy.

Wouldn't a trio of ice cream toppings make a magnificent hostess gift?  I thought the toppings looked especially cute in small glass milk bottles.  I bought mine in the dollar section at Target, but I don't know if they're still there.  You can definitely find them on Amazon (like these ones).

You can find the hot fudge recipe here, and the strawberry sauce recipe here.
