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
- Make a batch of Hazelnut Syrup ahead of time if you don’t have one.
- Whisk 1 scoop of whey protein into 8oz of cold milk until completely smooth.
- Pull a double shot of espresso into your cup and stir in 2 tbsp of the syrup while it’s hot.
- Steam or froth the protein-milk mixture and pour it over the espresso-syrup mix.
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.
