Prep Time:2 minutes
Cook Time:8 minutes
Total Time:10 minutes

Equipment

  • Measuring cups and spoons
  • Sheet pan
  • Medium Saucepan

Ingredients

  • 1 cup mini marshmallows
  • 1 cup water
  • 3/4 cup granulated sugar
  • 2 teaspoons vanilla extract

Instructions

  • Place the marshmallows on a sheet pan in an even layer. Broil for 1 to 2 minutes, watching closely, until they are golden brown.
  • Transfer the toasted marshmallows to a medium saucepan with the water and sugar. Bring the mixture to a simmer over medium heat and cook, stirring occasionally, until the marshmallows are fully melted and the sugar is dissolved, about 5 to 7 minutes.
  • Remove from heat and stir in the vanilla extract. Let the syrup cool completely.
  • Transfer to an airtight container for storage.

Notes

  • Toast marshmallows until deep golden brown for the best flavor. If they’re too light, the syrup will taste more like plain vanilla than toasted marshmallow.
  • Stir the syrup occasionally while it simmers to help everything melt evenly and prevent sticking.
  • Add 1/2 to 1 teaspoon of corn syrup while cooking if you want to help prevent crystallization as it cools.
  • Store in an airtight container in the refrigerator for up to two weeks.
  • Add 1 to 2 tablespoons to coffee, lattes, chai tea, or dirty sodas when serving.
  • Mini marshmallows melt faster and more evenly, but regular marshmallows can be used if needed.
  • Brown sugar can be used instead of granulated sugar for a deeper, slightly molasses flavor.
  • Use 1 teaspoon of vanilla bean paste instead of vanilla extract if that’s what you have on hand.
  • Marshmallows can be toasted under the broiler, with a kitchen torch, or over an open flame. If using an open flame, strain the syrup before storing to remove any charred bits.
