Mocha Protein Iced Coffee

⏱ 3 min total
💪 28g protein
🍽 1 tall iced coffee
If you need caffeine and protein in the same cup but do not want to drag out the blender, this is the fix. Cold brew, chocolate or mocha whey, a splash of milk, ice, and a shaker bottle. 30 seconds of shaking gives you a coffee-shop iced mocha with 28g of protein and almost no sugar. The protein powder thickens it just enough to feel rich, and the cold brew keeps the coffee flavor strong even after the ice starts to melt.
Ingredients
- 1 scoop chocolate or mocha whey protein
- 1 cup cold brew coffee (or strong chilled coffee)
- ½ cup milk or unsweetened almond milk
- 1½ cups ice cubes
- 1 tsp unsweetened cocoa powder (optional, for deeper chocolate)
- Optional: 1 to 2 drops liquid stevia or 1 tsp sugar-free syrup
Equipment
- Shaker bottle: 20 to 32 oz with an internal whisk ball or wire screen
- Tall glass: 16 to 20 oz, ideally chilled in the freezer for 10 minutes
- Reusable straw: metal or silicone, wide enough for chunky ice
- No blender required: but if you want a blended mocha, see our Chocolate Protein Frappe recipe
Instructions
- Add the milk and ¼ cup of cold brew to the shaker bottle first. The protein needs a small amount of liquid to dissolve into before more is added.
- Add the chocolate whey, cocoa powder if using, and any sweetener. Seal and shake hard for 20 seconds until completely smooth and slightly foamy.
- Add the remaining cold brew. Shake briefly to combine, 5 more seconds is enough.
- Fill a tall glass with the ice cubes, then pour the mocha mix over the top. The foam will settle on top in a thin layer.
- Drink within 10 minutes. The foam holds for about that long before the ice dilutes it.

Per 16 oz iced coffee, made with unsweetened almond milk and chocolate whey. Numbers shift to about 240 kcal with 2% dairy milk.
Substitutions
- No cold brew: use 1 tsp instant coffee dissolved in ½ cup hot water, then chill for 10 minutes
- No mocha whey: use chocolate whey + 1 tsp instant coffee in the shaker for a DIY mocha flavor
- Dairy-free: any plant milk works. Oat milk gives the creamiest finish
- Higher protein: double scoop the whey and add ½ cup more cold brew. Pushes protein to 56g per glass
- Caramel macchiato style: swap cocoa for 1 tsp sugar-free caramel syrup
Tips
Add the protein to a small amount of liquid first, then add the rest. If you dump 1 cup of cold liquid on top of dry whey and shake, you will get clumps that stick to the sides of the bottle. The order is: a splash of milk, the powder, shake until dissolved, then everything else. Chill the glass in the freezer for 10 minutes before pouring: it keeps the drink colder and the ice melts more slowly. If you take it to-go in a sealed bottle, leave headspace for ice expansion.

FAQ
Will it foam in a shaker bottle?
Yes, especially with whey concentrate. Expect a 1-finger layer of foam on top. If you do not want foam, stir with a long spoon instead of shaking.
Can I drink it hot?
Whey clumps in hot liquid above 130°F. For a hot mocha, brew the coffee, let it cool to lukewarm, then stir in the whey. Or use a milk frother on cold milk first.
How long does cold brew last?
Up to 14 days in a sealed jar in the fridge. Make a batch on Sunday and you have iced coffees ready all week.
Is this better than a Starbucks iced mocha?
On macros, yes. A grande iced mocha has 13g protein and 35g sugar. This has 28g protein and 4g sugar.
Why is mine grainy?
You added the whey directly to cold liquid. Always shake the powder into a small splash of milk first, then add the rest.
Can I use casein instead of whey?
Yes, but the drink will be much thicker, almost pudding-like. Add an extra ¼ cup of milk if you go that route.
