What Does the Iced S'mores Chai Taste Like?

This drink tastes like a campfire treat wrapped in warm chai spices — think cinnamon, cardamom, and ginger meeting sweet, toasty marshmallow flavor. It's spiced, cozy, and surprisingly well-balanced.

The mocha drizzle adds a rich chocolatey layer, while the crushed graham crackers bring that classic s'mores graham cracker taste. It's a totally unique flavor combo that somehow makes complete sense the moment you taste it.

Ingredients Needed

This Iced S'mores Chai comes together with a handful of simple ingredients — here's what you'll need!

• Chai concentrate — The spiced, warming base of this drink. My Homemade Chai Tea Concentrate is incredible here and already perfectly sweetened.
• Milk of choice — Any milk works beautifully. The recipe uses 2%, but oat milk or whole milk both work great too.
• Heavy cream and whole milk — Together they give the marshmallow cold foam its rich, silky, pourable texture.
• Toasted marshmallow syrup — Adds that signature sweet, toasty marshmallow flavor to the cold foam. My homemade Toasted Marshmallow Syrup is the move here.
• Mocha sauce — Adds a rich, chocolatey drizzle on top. Use chocolate syrup as a simple swap if needed.
• Crushed graham crackers — The finishing touch that gives this drink its classic s'mores crunch.

Substitutions

• No homemade chai concentrate? Store-bought chai concentrate works great too! Just check the label — most are pre-sweetened, similar to my homemade version. See the note below on marshmallow syrup if yours happens to be unsweetened.
• No mocha sauce? Chocolate syrup works perfectly as a simple 1:1 swap.
• No toasted marshmallow syrup? Use regular vanilla syrup plus a few drops of marshmallow extract for a similar sweet, marshmallow-y flavor.
• Dairy-Free: Swap the heavy cream and whole milk in the cold foam for full-fat coconut cream and oat milk. It'll still be creamy and delicious!

How to Make Iced S'mores Chai

This drink comes together in three simple steps, and it's just as easy as it sounds!

• Step 1 — Whip up the marshmallow cold foam first. Combine the heavy cream, toasted marshmallow syrup, and whole milk in a small glass or jar, then froth with a milk frother until light and foamy. Set it aside.
• Step 2 — Fill a tall glass with ice, then pour in the chai concentrate and milk of choice. If you're using an unsweetened chai concentrate, stir in the marshmallow syrup here too (see the note below for more on this). Give everything a good stir.
• Step 3 — Spoon the marshmallow cold foam over the top, drizzle with mocha sauce, and finish with a sprinkle of crushed graham crackers. Enjoy right away!

Optional Variations

• Graham cracker rim — Wet the rim of your glass and dip it in crushed graham crackers for that classic, picture-perfect s'mores presentation.
• Toasted mini marshmallow topping — Use a kitchen torch to lightly toast a few mini marshmallows and add them right on top of the cold foam.
• Hot S'mores Chai — Skip the ice and warm the chai and milk on the stovetop for a cozy, hot version of this drink — perfect for cooler days.
• S'mores Chai Frappuccino — Blend the whole drink with ice for a frozen, frappuccino-style treat. If you love that blended texture, you'll also want to try my S'mores Frappuccino!

A Note on Marshmallow Syrup

Here's something interesting about how Starbucks builds this drink: their chai base is unsweetened, so they add marshmallow syrup directly into the chai itself to sweeten it. But most chai concentrates — including my homemade version — are already sweetened on their own.

That means if you're using an already-sweetened chai concentrate, there's no real need to add extra marshmallow syrup to the base. The marshmallow cold foam on top already brings plenty of that flavor!

However, if you're using an unsweetened chai concentrate, go ahead and stir in 1-2 tablespoons of toasted marshmallow syrup directly into the chai for that authentic Starbucks sweetness.

Tips for the Best Iced S'mores Chai

• Use a good quality chai concentrate. Since chai is the star of this drink, a flavorful, well-spiced concentrate makes all the difference. Homemade is best!
• Don't over-froth the cold foam. You want it foamy and pourable, not stiff. A quick 5-15 seconds with the milk frother is usually perfect.
• Drizzle the mocha sauce right before serving. This keeps the presentation looking gorgeous and ensures the drizzle doesn't get lost in the foam.
• Taste your chai before adding extra marshmallow syrup. Since most concentrates are already sweetened, give your chai a taste first to see if you even need the extra syrup in the base.
