KEY INGREDIENTS IN TOASTED MARSHMALLOW COFFEE SYRUP
Every great recipe starts with quality ingredients that each play a special role in building flavor and texture. This syrup relies on a harmonious balance of sweetness, richness, and that unmistakable marshmallow character. Let’s break down what you’ll need and why each component matters:
- Granulated Sugar
The backbone of our syrup, sugar dissolves into the water to create a smooth, sweet base. As it simmers, it slightly caramelizes, adding depth and a light amber hue.
- Water
Water acts as the dissolving medium for sugar, ensuring you end up with a pourable, cohesive syrup rather than a dry, clumpy mess. It helps control the consistency.
- Vanilla Extract
A splash of vanilla brings floral, aromatic notes that complement the sweetness, rounding out the flavor profile and giving the syrup its signature warmth.
- Salt
Just a pinch of salt enhances all the flavors, balancing the sweetness and brightening the overall taste so it never feels cloying.
- Mini Marshmallows
The star of the show, marshmallows melt into a luxuriously creamy texture thanks to their gelatin content. When combined with the sugar mixture, they infuse the syrup with that toasty sweetness we love.
HOW TO MAKE TOASTED MARSHMALLOW COFFEE SYRUP
Creating this syrup is a fun, hands-on process that transforms a handful of simple ingredients into liquid gold. Follow these steps carefully, and soon you’ll be drizzling marshmallow magic on everything from lattes to pancakes.
1. In a medium saucepan, combine the granulated sugar and water. Heat over medium heat, stirring constantly with a heat-resistant spoon or spatula until the sugar is completely dissolved and the liquid is clear.
2. Bring the mixture to a gentle simmer, adjusting the heat as needed to maintain small, steady bubbles. Allow it to cook for about 3–4 minutes without stirring so it can thicken slightly and develop a light caramel color.
3. Remove the saucepan from heat and carefully stir in the vanilla extract and salt, whisking until fully incorporated and the mixture smells wonderfully sweet and aromatic.
4. Prepare a double boiler by placing a heatproof bowl over a saucepan of simmering water. Add the mini marshmallows to the bowl, ensuring the bottom of the bowl doesn’t touch the water.
5. Stir the marshmallows continuously with a silicone spatula until they melt completely and form a smooth, glossy mixture.
6. Gently combine the melted marshmallows with the sugar syrup in the saucepan. Stir thoroughly to integrate both mixtures into a seamless, velvety syrup.
7. Allow the syrup to cool slightly in the saucepan—just enough so it’s safe to handle—then transfer it to a clean jar or bottle using a funnel to minimize spills.
8. Let the syrup cool completely before sealing the jar or bottle. Store in the refrigerator for up to one month, shaking gently before each use.

There’s no limit to the delicious ways you can enjoy this homemade toasted marshmallow coffee syrup. From morning pick-me-ups to decadent dessert toppers, here are some creative ideas to get you started and ensure each serving is as dreamy as possible.
- Swirled Into Hot Coffee

- Drizzled Over Vanilla Ice Cream
Pile scoops of creamy vanilla ice cream into a bowl and drizzle generously with the syrup. The contrast between the cold ice cream and warm, sticky sweetness is pure bliss.

HOW TO STORE TOASTED MARSHMALLOW COFFEE SYRUP
Proper storage ensures your toasted marshmallow coffee syrup maintains its sweet, gooey texture and vibrant flavor over time. With just a bit of care, you’ll have syrup on hand whenever you need a quick, luxurious boost to your drinks or desserts.
- Refrigerate in an Airtight Jar
After the syrup cools completely, transfer it to a clean, dry glass jar or bottle with a tight-fitting lid. Store in the coldest part of your fridge, and it will stay fresh for up to one month.
- Label with Date
Use a simple sticker or piece of masking tape to note the date you made the syrup. This helps you keep track of freshness and ensures you enjoy it at its best.
- Avoid Contamination
Always use a clean spoon or utensil when scooping out syrup. Introducing crumbs or liquids from other foods can shorten the syrup’s shelf life and affect its flavor.
- Freeze in Ice Cube Trays
For longer storage, pour syrup into ice cube trays and freeze. Once frozen solid, pop the cubes out and store them in a freezer bag. Use cubes to sweeten and flavor hot or cold drinks without thawing an entire batch.
