½ cup marshmallow spread
½ cup canned pumpkin
½ cup packed light brown sugar
¼ cup plus 2 tablespoons water

Variations

Spiked version: Add 1 tbsp bourbon or spiced rum after cooking
Extra creamy: Stir in 1 extra tablespoon of heavy cream for a richer texture
Vegan: Use coconut cream instead of heavy cream and a vegan marshmallow spread
Sweeter version: Add 1 extra tablespoon of brown sugar for a more caramel-like flavor

Storage and Heating

Refrigerator:
Store in an airtight jar or bottle in the fridge for up to 1 week.

Reheating:
To reheat, scoop or pour desired amount into a microwave-safe container and heat in 10-second bursts, or warm gently in a small saucepan.

Freezing is not recommended due to the dairy and marshmallow content.
