Homemade Marshmallow Sauce

A few weeks ago we had some friends over for an ice cream sundae bar and one of the toppings I made was this homemade marshmallow sauce. I’ve made this a few times in the past and each time I am always amazed at how delicious it turns out and how easy it is to make.

If you are making ice cream sundaes, I highly recommend you double up on the sauces and top your ice cream with both hot fudge sauce and marshmallow sauce. Or raspberry sauce and marshmallow sauce.

Basically, marshmallow sauce makes everything more delicious. It’s amazing stuff, especially over cherry, chocolate, or strawberry ice cream.

Marshmallow sauce is a sticky, gooey topping that is like pouring liquid marshmallows over whatever you are eating. 

Plus, this marshmallow sauce can pull double duty as a fruit dip or added to peanut butter for a fluffernutter sandwich. Or mix it into a batch of regular buttercream to make marshmallow buttercream frosting that you can use on cupcakes or in whoopie pies. And it keeps in the fridge for up to a month!

Ingredients for Homemade Marshmallow Ice Cream Topping

  • water
  • unflavored powdered gelatin
  • granulated sugar
  • corn syrup
  • vanilla
  • salt

How to Make Homemade Marshmallow Sauce for Ice Cream

  1. In the mixing bowl of a stand mixer with a whisk attachment, mix the gelatin with 1/2 cup of the cold water for a few seconds, then let it sit for 5 minutes so the gelatin can bloom.
  2. In a saucepan, bring the sugar, corn syrup, salt and remaining 1/2 cup cold water to a boil over medium­-high heat.
  3. Continue cooking until the temperature reaches 240 degrees F on a candy thermometer, then remove from heat and pour over the gelatin mixture.
  4. Add the vanilla extract and beat on low speed for 2 minutes. Increase the speed to high and beat for about 10 to 12 minutes until the mixture turns thick, white and glossy.
  5. Store in an airtight container in the fridge for up to a month.
