2 tablespoon toasted marshmallow syrup

Ice
Optional: crushed graham crackers, toasted marshmallows for topping

How to Make Toasted Marshmallow Syrup

Toast the Marshmallows: Place marshmallows on a parchment-lined baking sheet and broil for 1–2 minutes until golden brown and charred in spots. Keep a close eye—they toast fast!
Make the Syrup: In a small saucepan, combine water, sugar, and toasted marshmallows over medium heat. Stir until sugar dissolves.
Simmer for 3–5 minutes, stirring constantly to help the marshmallows melt.
Strain the syrup through a fine mesh sieve into a jar. Let cool before using. Store in the fridge for up to 1 week.

How to Make the Iced S’mores Latte

Drizzle chocolate syrup around the inside of the glass.
Fill a tall glass with ice.
Pour in the toasted marshmallow syrup and milk. Stir to combine.
Add the espresso over the top.
In a small cup combine heavy cream, milk, and marshmallow syrup, froth until thick and cream then pour over the top.
Garnish with crushed graham crackers, and a few toasted marshmallows for that true s’mores vibe.

Tips & Variations

Make it extra toasty: Use a kitchen torch to toast mini marshmallows right on top of your whipped cream.
Blended Version: Blend it all with ice for a frozen s’mores frappe!\
Make it Hot: Skip the ice and steam the milk.
