Ingredients for the Perfect Syrup
The magic of this recipe lies in balancing creamy sweetness with rich pumpkin flavor. Here’s what you’ll need:
-
Pumpkin Puree (¾ cup): Use pure pumpkin, not pumpkin pie filling. It brings authentic flavor and natural thickness.
-
Brown Sugar (1 cup): Provides caramel-like notes that deepen the syrup.
-
Granulated Sugar (½ cup): Balances the richness with bright sweetness.
-
Water (1 cup): Helps dissolve sugars and create a smooth syrup base.
-
Mini Marshmallows (1 ½ cups): The star ingredient, adding gooey sweetness and a silky finish.
-
Pumpkin Pie Spice (2 teaspoons): A warming blend of cinnamon, nutmeg, ginger, and cloves.
-
Vanilla Extract (1 teaspoon): Enhances both pumpkin and marshmallow flavors.
-
Pinch of Salt: Balances sweetness and makes the flavors pop.
Step-by-Step Recipe: Fall Pumpkin Marshmallow Coffee Syrup
Step 1: Create the Syrup Base
In a medium saucepan, combine water, brown sugar, and granulated sugar. Heat over medium, stirring occasionally, until the sugars fully dissolve.
Step 2: Add Pumpkin Flavor
Whisk in the pumpkin puree. Stir until the mixture becomes smooth and starts to thicken slightly. This creates a rich pumpkin base.
Step 3: Spice It Up
Sprinkle in the pumpkin pie spice and a pinch of salt. Stir well so the warm spices infuse every spoonful.
Step 4: Marshmallow Magic
Add the mini marshmallows gradually, stirring continuously. They will melt into the syrup, giving it a creamy, marshmallow-like body.
Step 5: Add Vanilla
Once smooth and glossy, remove the pan from heat. Stir in the vanilla extract.
Step 6: Strain and Store
For a silky finish, strain the syrup through a fine mesh sieve to remove any pumpkin fibers. Transfer into a glass jar or bottle, and refrigerate. It will keep for up to 2 weeks.
