Salted Caramel Protein Cold Brew
Uses Salted Caramel 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
StandardIngredients
- 1 cup (8oz) Cold Brew Concentrate (homemade or store-bought)
- 1 scoop (about 30g) whey protein powder, vanilla or unflavored
- 4oz milk or milk alternative of choice
- 2 tbsp Salted Caramel Syrup (make a batch ahead of time -- it keeps about 2 weeks in the fridge)
- Ice, as needed
- Optional: a pinch of flaky sea salt on top
Steps
- 1.Add the whey protein to a shaker bottle with the milk first -- mixing powder into liquid before the coffee goes in is the single biggest trick to avoiding clumps.
- 2.Add the 2 tbsp Salted Caramel Syrup to the shaker as well, then shake for 15-20 seconds until completely smooth.
- 3.Fill a glass with ice, pour in the cold brew concentrate, then pour the protein-milk-syrup mixture over it.
- 4.Stir to combine. Finish with a pinch of flaky sea salt on top if using, and serve immediately with a straw.

This is the cold-brew, whey-protein sibling to our regular Salted Caramel Latte — same double-salted syrup, same finishing pinch of flaky salt, moved onto a cold brew base with a scoop of protein shaken in instead of steamed milk poured over espresso.
Building the Drink
- Make a batch of Salted Caramel Syrup ahead of time if you don’t have one — it keeps about 2 weeks in the fridge.
- Add 1 scoop of whey protein and 4oz of milk to a shaker bottle, along with the 2 tbsp of syrup.
- Shake for 15-20 seconds until completely smooth.
- Fill a glass with ice, pour in 1 cup of cold brew concentrate, then pour the protein mixture over it. Stir, finish with a pinch of flaky salt if using, and serve with a straw.
Assumptions: homemade cold brew concentrate at this site’s standard $16/lb bean pricing, whey protein at ~$0.88/scoop, dairy milk, and a homemade Salted Caramel Syrup batch. At 5 drinks a week over the site’s standard 48-week year, that’s roughly $1,166/year back in your pocket.
Swaps & Notes
- Plain caramel instead of salted? Swap in Caramel Syrup for an unsalted version, or see our Protein Caramel Latte for a steamed-milk latte take on the same flavor.
- Skip the salt pinch if you’re sodium-conscious — it’s a garnish, not load-bearing for the syrup’s flavor (the syrup itself is already “double-salted” per its own recipe).
- Protein total: about 24g from the whey scoop, plus roughly 4g from the 4oz of dairy milk — around 28g total.

FAQ
Does the salt in the syrup clash with the protein powder’s flavor?
No — salt and sweet is a well-established pairing, and most vanilla or unflavored wheys have a mild enough base flavor that the salted caramel comes through clearly as the dominant note.
How is this different from your regular Salted Caramel Latte?
That recipe is a hot (or iced) espresso-and-steamed-milk latte with no protein powder. This one is cold-brew-based with a whey scoop shaken in — different base, different protein content, same syrup.
Can I make this with decaf cold brew?
Yes — decaf cold brew concentrate works exactly the same way in this recipe; only the caffeine content changes, not the cost or protein math.
