Think simple syrup is just sugar and water? Think again.
This Toasted Marshmallow Simple Syrup takes under 10 minutes to make and adds rich, velvety depth to cocktails, mocktails, coffee, and beyond.
With subtle smoky sweetness and a creamy finish, it’s the kind of syrup that instantly makes a drink feel elevated—like going from backyard bonfire to luxury glamping in one pour.
Whether you’re crafting a boozy dessert martini, an aged spirit-forward nightcap, or a cozy coffee cocktail, this syrup gives you something regular simple syrup can’t: flavor with personality.
And it’s shockingly easy to make.
Recently I mixed up a Scotch old-fashioned called the Glampfire Old Fashioned using this syrup, and it added a beautiful depth and unique flavor that I didn’t get using regular simple syrup.
That’s the magic of it: familiar flavors, reinvented.
Toasted marshmallow brings notes of smoke, vanilla, and caramel, and the syrup’s texture gives your drink a slightly thicker, more luxurious mouthfeel.
I’ve used this syrup in everything from a dark rum s’mores martini to a dressed-up whiskey sour, and even in mocktails and hot cocoa. It adds just enough indulgence to feel special without tipping too sweet.
And here’s the kicker: I’m usually the first person to skip sweeteners if I can—but ever since I started making this toasted marshmallow version, it’s become a regular in my home bar.
It’s cozy, versatile, and totally worth having on hand.
Step 1: In a small saucepan set over medium heat add all ingredients.
Step 2: Bring to a boil. Then simmer for 5 minutes or until the sugar is completely dissolved.
Step 3: Pour the cooled syrup into glass bottles or jars with tight-fitting lids.
Decadent, and delicious, this syrup stores well for about a month in the fridge, and this recipe creates just about a small mason jar full.
I promise, you’ll be able to finish the whole mason jar before the month ends. Yes, it’s that good.
Try it with:
Bourbon or rye for a wintery twist on a classic sour
Espresso and vodka for a fireside-inspired martini
Dark rum and chocolate bitters for a s’mores nightcap
Cinnamon-spiced mocktails for a kid-friendly option with grown-up flavor
This syrup bridges the gap between comfort and craft, transforming everyday drinks into something memorable.
If you’ve never experimented with flavor-infused syrups, this is where to start.
The bottled syrup will keep in the fridge for up to 1 month.
