5-Minute Iced Protein Coffee
This iced protein coffee is creamy, filling, and ready in 5 minutes. It’s the kind of drink that actually keeps you full until lunch.

You only need a few ingredients and a blender, and you’ve got a cool coffee with a boost of protein. It works with any milk you have and is easy to make dairy-free.
Why I Reach for This Iced Coffee
Most protein coffees end up chalky or separate into a watery mess. This one blends smooth and stays creamy because the cold brew and milk emulsify with the powder in seconds.
It tastes like a lightly sweetened latte, not a supplement. And it costs a fraction of a coffee shop protein drink.
Ingredients

- 1 cup cold brew coffee: use a smooth, not-too-bitter cold brew or strong chilled coffee
- 1 cup milk of choice: whole milk gives the richest taste; almond, oat, or soy all work
- 1 scoop (about 1/4 cup) vanilla protein powder: pick a brand you enjoy drinking
- 1 tsp maple syrup: optional, just to round out the flavor
- 1 cup ice cubes: plus more for serving
- Pinch of ground cinnamon: for garnish, optional
Variations / Substitutions
- Protein powder: swap vanilla for chocolate or unflavored. Whey, pea, and collagen all blend well.
- Milk: oat milk makes it extra creamy; almond milk keeps it light.
- Sweetener: honey, agave, or a date syrup work in place of maple.
- Flavor add-ins: blend in half a frozen banana for a thicker shake, or 1 tbsp cocoa powder for a mocha.
If you want a blended frozen coffee treat, my Mocha Protein Smoothie is another favorite.
How to Make Iced Protein Coffee
Step 1: Blend the Coffee Base

Add the 1 cup cold brew coffee, 1 cup milk, 1 scoop protein powder, and 1 tsp maple syrup to a blender. Blend on high for 30 seconds, until the mixture is smooth and no powder lumps cling to the sides. This quick blend is what gives the drink its creamy, latte-like body.
Step 2: Pour and Serve

Fill a tall glass with ice cubes. Pour the blended coffee over the ice and top with a pinch of cinnamon if you like. Drink it right away while it’s thick and frosty.
A Few Tips for Smoother Coffee
- If your cold brew is a concentrate, dilute it with water until it tastes like regular strength coffee before blending, or the drink will be harsh.
- For an even thicker, shake-like texture, blend in half a frozen banana. It adds natural sweetness too.
- Make coffee ice cubes: freeze leftover coffee in an ice tray and use those instead of plain ice to keep the drink from watering down.
Frequently Asked Questions
Can I make this the night before?
No, protein drinks separate and lose their creamy texture as they sit. It’s best blended and poured right when you want it.
I don’t have cold brew, only hot coffee. What now?
Pour the hot coffee over a glass of ice to chill it quickly, then blend. It will dilute slightly, so brew it stronger if you can. For the best result, chill brewed coffee overnight.
Is plant-based protein powder okay?
Yes, many plant-based proteins work, but some can be a bit grainy. Blending on high for a full 30 seconds helps smooth them out.
