    The BYOB Team5 min1 drink (from a batch of Hazelnut Syrup that makes about 12 servings)$1.79/drink340 cal/drink

    Uses Hazelnut Syrup — 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

    Standard

    Ingredients

    • 2oz espresso (or 1/3 cup strong coffee/moka pot equivalent)

    2. 2.Pull a double shot of espresso (about 2oz) directly into your serving cup.

    4. 4.Steam or froth the protein-milk mixture to about 150°F and pour it over the espresso-syrup mixture.

    This is our regular Hazelnut Latte with a scoop of whey blended into the milk — one of the most classic, year-round flavors on this site, now built to also carry a real protein number.

    Building the Latte

    1. Make a batch of Hazelnut Syrup ahead of time if you don’t have one.
    2. Whisk 1 scoop of whey protein into 8oz of cold milk until completely smooth.
    3. Pull a double shot of espresso into your cup and stir in 2 tbsp of the syrup while it’s hot.
    4. Steam or froth the protein-milk mixture and pour it over the espresso-syrup mix.
    Café Protein Hazelnut Latte vs. Home Version
    Café hazelnut latte with a protein add-on~$7.05
    Home protein hazelnut latte~$1.79
    Savings per drink$5.26

    Assumptions: grande-size drink, national-average café pricing for a hazelnut-flavor latte plus a protein add-on, dairy milk, $16/lb specialty beans or equivalent grocery beans, whey protein at ~$0.88/scoop. No seasonal ceiling on this one. At 5 drinks a week over the site’s standard 48-week year, that’s roughly $1,262/year back in your pocket versus the café version.

    Swaps & Notes

    • Iced version: use the Hot/Iced toggle above the ingredients for less milk (4oz cold, shaken with the protein, instead of 8oz steamed).
    • Want a mocha-hazelnut combo? See our Hazelnut Mocha Latte for the non-protein two-flavor version — a protein take works the same way, add a whey scoop and use half portions of each syrup.
    • Protein total: about 24g from the whey scoop, plus roughly 8g from the 8oz of dairy milk — around 32g total (28g on the iced 4oz-milk version).

    FAQ

    Does the hazelnut flavor come from real nuts?

    See Hazelnut Syrup for the full ingredient breakdown — the syrup recipe uses hazelnut extract rather than whole nuts, which keeps the cost and prep time down while still delivering a real hazelnut flavor.

    Will the protein powder make the drink taste chalky?

    Not if you whisk it into cold milk first and steam it in properly — the most common cause of a chalky protein latte is stirring powder directly into a finished hot drink instead of blending it into the milk beforehand.

    Can I use a hazelnut-flavored protein powder instead of plain whey plus the syrup?

    Yes, though most hazelnut-flavored proteins taste noticeably more artificial than the real syrup — we’d recommend the syrup version for a better flavor payoff, but the flavored-powder shortcut works if you’re optimizing for speed over taste.
