Ingredients

Units Scale

Syrup Base

  • 1/2 cup marshmallow spread
  • 1/2 cup canned pumpkin
  • 1/2 cup packed light brown sugar
  • 1/4 cup plus 2 tbsp water
  • 2 tbsp heavy whipping cream
  • 1 tsp pumpkin pie spice blend

Finishing Ingredients

  • 1/2 tsp vanilla extract or vanilla bean paste
  • Small pinch fine sea salt

Instructions

  1. Combine and Heat the Syrup Base: In a medium saucepan over low heat, combine the marshmallow spread, canned pumpkin, light brown sugar, water, heavy whipping cream, and pumpkin pie spice blend. Stir constantly and gently heat the mixture until the sugar fully dissolves and the syrup becomes smooth, about 5 minutes. Avoid boiling to preserve texture and flavor.
  2. Finish and Cool the Syrup: Remove the saucepan from heat and stir in the vanilla extract or vanilla bean paste along with a small pinch of fine sea salt. Mix thoroughly to blend all flavors. Allow the syrup to cool completely in the pan before transferring it to a clean jar or bottle. Refrigerate the syrup, where it will keep fresh for up to one week.

Notes

  • Do not let the mixture boil to prevent separation and maintain a smooth syrup consistency.
  • Use vanilla bean paste for a more intense vanilla flavor and visible specks.
  • Store refrigerated in a tightly sealed container for up to one week.
  • Shake or stir the syrup before use if separation occurs.
  • Ideal for coffee, lattes, or as a sweet drizzle over desserts.
