You could also add some caramel to really sweeten the deal.

Marshmallow sauce is so much better than just tossing a few classic, solid marshmallows on top of your ice cream or brownie because it is more evenly dispersed and less chewy, pairing beautifully with the rest of your dessert without overpowering it.

You can even make your own sprinkles if you want to go all out!

Homemade Marshmallow Sundae Sauce FAQ

Can I use marshmallow sauce as a filling for cakes or cupcakes?

Notes

I combed through several recipes before finally settling on this one, and I'm so glad I did. All of the recipes that were made completely from scratch (so, marshmallows aren't one of the ingredients) had a common reader complaint that the homemade sauce stiffened up too much once drizzles on the ice cream.

This recipe, however, is PERFECT. It stays sauce-like after it's drizzled on the ice cream and is extremely easy to scoop up with your ice cream 🙂

Vanilla will discolor the marshmallow cream a little bit, so be sure to use clear vanilla if you want to keep it pure white.
