Toasted Marshmallow Syrup
This sweet homemade toasted marshmallow syrup is made with real toasted marshmallows, vanilla, and a simple sugar syrup base. Use it to flavor coffee, cold brew, iced lattes, mochas, hot chocolate, and homemade cold foam.
Ingredients
- 8 regular-size marshmallows or approximately 1 cup mini marshmallows
- 1 cup granulated sugar
- 1 cup water
- 1 tsp vanilla extract
- small pinch of salt
Instructions
- Line a metal baking sheet with aluminum foil and arrange the marshmallows in a single layer. Lightly grease the foil if desired.
- Place the marshmallows under the broiler and watch them continuously. Toast for approximately 30 seconds to 2 minutes, or until deeply golden brown with a few darker toasted spots.
- Toasting one side is sufficient. Carefully turn only the marshmallows that remain firm enough to handle, then briefly toast the second side if desired. Remove them from the oven and set aside.
- Add the sugar and water to a small saucepan over medium heat.
- Stir until the sugar completely dissolves, then bring the mixture to a gentle simmer.
- Reduce the heat to low and add the toasted marshmallows.
- Stir continuously until the marshmallows have melted and the mixture is smooth.
- Remove the saucepan from the heat.
- Stir in the vanilla extract and a small pinch of salt.
- For an extra-smooth syrup, strain the warm mixture through a fine-mesh strainer into a heat-safe jar.
- Allow the syrup to cool completely before covering and refrigerating.
Notes
- Broilers vary in strength, so watch the marshmallows continuously while they toast.
- For the strongest toasted flavor, allow the marshmallows to become deeply golden with some dark brown areas, but avoid burning them completely.
- The syrup thickens as it cools and becomes even thicker in the refrigerator.
- If the refrigerated syrup is too thick, stir in warm water one teaspoon at a time.
- For iced espresso drinks, mix the syrup with warm espresso before adding milk and ice.
- Start with 1 tablespoon for smaller drinks and use up to 2 tablespoons for larger iced drinks.
- When flavoring cold foam, start with 1 to 2 teaspoons of syrup per serving so the foam does not become too thin.
- Store in a clean, airtight container in the refrigerator and use within 1 to 2 weeks.
- The syrup has about 40 calories per tablespoon.
