Ingredients

Scale

Syrup Base

  • 1/2 cup marshmallow spread (Fluff recommended for smooth texture)
  • 1/2 cup canned pumpkin (Libby’s for best flavor)
  • 1/2 cup packed light brown sugar
  • 6 tbsp water
  • 2 tbsp heavy whipping cream
  • 1 tsp pumpkin pie spice blend (freshly ground preferred)
  • 1/2 tsp vanilla extract (pure vanilla for best flavor)
  • 1 pinch fine sea salt

Instructions

  1. Combine and Gently Heat Base Ingredients: In a medium saucepan, combine the marshmallow spread, canned pumpkin, light brown sugar, water, heavy whipping cream, and pumpkin pie spice blend. Place the saucepan over medium-low heat and whisk constantly to fully incorporate the ingredients and dissolve the sugar. Keep the heat low to avoid scorching, stirring often to prevent sticking and to melt the marshmallow completely, creating a smooth, cohesive syrup base.
  2. Infuse with Vanilla and Salt, Then Cool: Once the mixture is smooth and the sugar has dissolved, immediately remove the saucepan from the heat. Stir in the vanilla extract and a pinch of fine sea salt, allowing the residual heat to meld these flavors into the syrup. Let the syrup cool completely to room temperature to deepen flavors and thicken the syrup slightly before using or storing.

Notes

  • Use pure vanilla extract for the best flavor impact.
  • Freshly ground pumpkin pie spice will provide a more vibrant spice profile.
  • Allow the syrup to cool fully before adding to cold drinks to avoid separation.
  • The pinch of salt enhances the sweetness and highlights the other flavors.
  • Store syrup in a sealed container in the refrigerator for up to two weeks.
