    Same drink, three ways. Ingredient-Honest is our top recommendation -- Standard and Sugar-Free are the other options.

    Uses Cold Brew Concentrate (Plain, No Protein) — make a batch ahead of time; it keeps in the fridge for a week or two, so you won't need to make it again for every drink.

    Ingredients & steps

    Sugar-Free

    Ingredients

    • 4oz Cold Brew Concentrate (homemade or store-bought)
    • 2 tbsp Sugar-Free Toasted Marshmallow Syrup (make a batch ahead of time -- it keeps about 2 weeks in the fridge)
    • 2oz cold heavy cream (36%+ milkfat)
    • 2oz cold whole milk (or milk alternative)
    • Ice (enough to fill a 16oz glass)

    Steps

    1. 1.Make a batch of Sugar-Free Toasted Marshmallow Syrup ahead of time if you haven't already -- it's a once-every-couple-weeks step, not a per-drink one.
    2. 2.Fill a 16oz glass with ice.
    3. 3.Pour 4oz cold brew concentrate over the ice, then stir in 2 tbsp of the syrup until dissolved.
    4. 4.In a separate small cup or jar, whisk together 2oz cold heavy cream and 2oz cold whole milk -- this is the light sweet cream blend. It should look just barely thickened, not whipped.
    5. 5.Pour the cream blend over the top and stir it all the way through, 2-3 stirs. Serve immediately with a straw.

    This is the sugar-free build of our Toasted Marshmallow Cream Cold Brew — allulose-sweetened marshmallows, broiled the same way as the Standard syrup, mixed into cold brew with a light poured cream.

    An Honest Note on the Calories Here

    This is the one flavor in this whole 12-recipe family where “sugar-free” doesn’t mean “near-zero calorie.” Our other Sugar-Free syrups (Vanilla, Mocha, Caramel) land between 1 and 9 calories per serving, because they’re just water, a zero-calorie sweetener, and an extract. Real marshmallow — sugar-free or not — is a whipped structure of gelatin and bulking carbohydrates that carries its own calories regardless of the sweetener, so this syrup runs 26 calories per serving. Still a real cut from the Standard syrup’s 51, just not the same order of magnitude as this family’s other sugar-free flavors.

    Building the Drink

    1. Fill a 16oz glass with ice and pour 4oz Cold Brew Concentrate over it, then stir in 2 tbsp of the sugar-free toasted marshmallow syrup until dissolved.
    2. Separately, whisk 2oz cold heavy cream with 2oz cold whole milk until just loosely combined.
    3. Pour the cream blend over the top and stir it all the way through. Serve immediately.
    Chick-fil-A Toasted Marshmallow Cream Cold Brew vs. This Version
    Chick-fil-A Toasted Marshmallow Cream Cold Brew (medium)~$4.25 / 520 cal
    Home Sugar-Free Toasted Marshmallow Cream Cold Brew~$1.56 / 266 cal

    Savings per drink: about $2.69, and 254 fewer calories (49% less) than Chick-fil-A’s own published nutrition figures (520 cal per chick-fil-a.com; price is representative, per multiple 2026 menu-price trackers).

    Assumptions: sugar-free marshmallows at specialty pricing, standard grocery heavy whipping cream (~$4.29/pint), and Kirkland Signature Organic A2 Whole Milk.

    Swaps & Notes

    • Want the lowest-calorie version of this flavor possible? Use a lower-fat milk (2% or unsweetened almond) in place of the whole milk portion of the cream blend — the heavy cream is the bigger calorie driver of the two, so this mainly trims the smaller half.
    • Prefer the real thing? See the Standard tier. Prefer a build with no marshmallow at all? See the Ingredient-Honest tier.

    Sugar-Free Toasted Marshmallow Cream Cold Brew

    FAQ

    Is this actually low-calorie, or just lower than the Standard version?

    Lower, genuinely — but not near-zero the way this site’s other sugar-free syrups are. See the honest note above on why real marshmallow doesn’t get there.

    Do I need to make a fresh batch of syrup for every drink?

    No — the syrup batch keeps about 2 weeks and covers roughly 8 drinks.

    Can I make this even lighter?

    Yes — swap the whole milk portion of the cream blend for a lower-calorie milk. The heavy cream itself is fixed (it’s what gives the drink its body), but the milk half of the blend is an easy place to cut further.
