What Does the S'mores Cold Brew Taste Like?
This drink tastes exactly like a campfire s'more in coffee form — sweet, toasty marshmallow flavor swirled into bold, smooth cold brew coffee. The toasted marshmallow syrup gives it that warm, slightly caramelized sweetness that makes marshmallows so irresistible in the first place.
The mocha drizzle adds a rich, chocolatey layer that ties everything together, while the crushed graham crackers on top bring that classic s'mores graham cracker flavor. It's sweet, cozy, and just nostalgic enough to make every sip feel like a treat.

Ingredients Needed
- Heavy cream and whole milk — Together they give the marshmallow cold foam its rich, silky, fluffy texture.
- Toasted marshmallow syrup — The star of the show! It flavors both the cold foam and the cold brew base, adding that warm, toasty marshmallow sweetness that makes this drink so special. I love using my homemade Toasted Marshmallow Syrup for the best flavor.
- Cold brew coffee — The bold, smooth coffee base of this drink. The stronger the cold brew, the better it stands up to all that sweetness on top.
- Mocha sauce — Adds a rich, chocolatey drizzle on top. Our homemade Mocha Sauce is incredible here, or use chocolate syrup as a simple swap.
- Crushed graham crackers — The finishing touch that gives this drink its classic s'mores crunch. Don't skip it!
Substitutions
- No mocha sauce? Chocolate syrup works great as a simple 1:1 swap — it's already noted as an option in the recipe!
- No toasted marshmallow syrup? Use regular vanilla syrup plus a few drops of marshmallow extract for a similar sweet, marshmallow-y flavor. Or make your own with our Toasted Marshmallow Syrup recipe — it's so easy!
- 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, dreamy, and delicious!
How to Make S'mores Cold Brew
This drink comes together in three easy steps — and the hardest part is not eating all the crushed graham crackers before they make it onto your drink!
- Step 1 — Start with the cold foam. Combine the heavy cream, toasted marshmallow syrup, and whole milk in a small glass or jar, then froth everything together with a milk frother until light and airy. Set it aside while you build the rest of the drink.
- Step 2 — Fill a tall glass with ice and pour in the cold brew along with the remaining toasted marshmallow syrup. Give it a good stir so the syrup blends evenly into the coffee.
- Step 3 — Spoon the marshmallow cold foam over the top, finish with a drizzle of mocha sauce, and scatter the crushed graham crackers across the foam. Enjoy immediately!
Optional Variations
- Graham cracker rim — Wet the rim of your glass with a little water or syrup, then dip it in crushed graham crackers for that classic, picture-perfect s'mores presentation.
- Toasted marshmallow topping — Use a kitchen torch to lightly toast a few mini marshmallows and add them on top of the cold foam for an extra campfire touch.
- Extra chocolatey — Drizzle mocha sauce along the inside of the glass before adding ice for a beautiful mocha-swirled effect in every sip.
- Iced S'mores Latte — Swap the cold brew for espresso and steamed or cold milk for a creamier, latte-style version of this drink.
Tips for the Best S'mores Cold Brew
- Use a good quality cold brew. Since this drink is sweet and rich, a bold cold brew is what keeps it balanced. Weak coffee will get lost under all that marshmallow and chocolate!
- 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 all it takes.
- Drizzle the mocha sauce right before serving. This keeps the presentation looking gorgeous and ensures the drizzle doesn't get lost in the foam.
- Adjust the marshmallow syrup to taste. Love it extra sweet and toasty? Add a little more syrup. Prefer it more coffee-forward? Scale back slightly. This recipe is totally flexible!
