This vanilla pumpkin marshmallow coffee syrup turns ordinary coffee moments into cozy seasonal rituals. Its creamy texture and warm autumn spices bring comforting sweetness that pairs beautifully with your morning brew or an afternoon latte.
I first made this syrup on a crisp fall morning, and it quickly became my go-to treat for lifting chilly days.
Ingredients
- Half a cup marshmallow spread: for a gooey, smooth texture that blends sweetness into every sip
- Half a cup canned pumpkin: to add natural richness and classic fall flavor—choose pure pumpkin puree, not pumpkin pie filling
- Half a cup packed light brown sugar: to provide deep, caramel-like sweetness; use light brown for balance without overpowering molasses notes
- A quarter cup plus two tablespoons water: to help dissolve ingredients and create syrup consistency
- Two tablespoons heavy whipping cream: to add velvety richness and help emulsify the mixture
- One teaspoon pumpkin pie spice blend: to introduce warm cinnamon, nutmeg, clove, and ginger—the signature fall spice combination
- Half a teaspoon vanilla extract or vanilla bean paste: for fragrant complexity and enhanced sweetness
- Small pinch fine sea salt: to balance the flavors and cut through the sweetness
Instructions
- Combine and Heat the Syrup Base:
- In a medium saucepan set to low heat, add the marshmallow spread, canned pumpkin, light brown sugar, water, heavy whipping cream, and pumpkin pie spice blend. Stir these ingredients constantly while gently warming the mixture. This should take about five minutes until the sugar fully dissolves and the syrup becomes smooth. Avoid letting it boil by keeping the heat low; the goal is a gently heated blend that fully incorporates all ingredients into a thick syrup.
- Finish and Cool the Syrup:
- Remove the saucepan from the heat source. Immediately stir in the vanilla extract or vanilla bean paste along with a small pinch of fine sea salt. Mix thoroughly so these ingredients are evenly distributed, enhancing the syrup’s flavor layers. Leave the syrup to cool completely in the pan to help it settle and thicken before transferring it into a clean jar or bottle. Storing the syrup in the fridge for up to one week keeps it fresh and ready to sweeten your coffee any time.

My favorite ingredient is the marshmallow spread because it gives the syrup that luxurious, almost fluffy mouthfeel that transforms regular coffee into something special. One chilly morning, I poured this syrup into my cup and instantly felt wrapped in warmth—the perfect start to fall.
Storage tips
Store the syrup in a tightly sealed jar or bottle in the refrigerator. Let it come to room temperature or warm slightly before use if it thickens too much when cold. Shake gently before pouring.
Ingredient substitutions
If you don’t have marshmallow spread, mini marshmallows melted gently can work as a substitute though the texture may be less smooth. You can swap heavy cream for half and half if you prefer a lighter syrup. Pumpkin pie spice can be replaced with equal parts cinnamon, nutmeg, ginger, and clove ground freshly if you like.
Serving suggestions
This syrup is fantastic drizzled over coffee, lattes, or even hot chocolate. Try stirring a small amount into whipped cream as a topping for coffee drinks or pancakes for an extra autumn twist.

This syrup perfectly captures the essence of fall and is easy to prepare anytime you want a cozy coffee moment.
