Iced Coffee Protein Shake (30g Protein)
An iced coffee protein shake hits the two morning needs at once: caffeine and protein. This version blends 30 grams of protein into a glass of cold brew with a splash of almond milk, and the whole thing clocks in under 200 calories. It is the perfect alternative to a sugary bottled protein coffee or a Starbucks Doubleshot, both of which are loaded with sugar and short on protein. Use cold brew if you have it (smoother, less acidic) or pull two shots of espresso and chill them briefly. The optional MCT oil gives it a creamy bulletproof-coffee feel without changing the macros much.
Ingredients
- 1 cup cold brew coffee (or 2 shots espresso + ½ cup water)
- 1 scoop vanilla or mocha whey (~25g protein)
- ½ cup unsweetened almond milk
- 1 tbsp MCT oil or heavy cream (optional)
- ½ tsp vanilla extract
- 1 cup ice cubes
- Dash of cinnamon (optional)
Equipment
- Blender or shaker bottle with frother
- Cold brew (store-bought or home brew, 1:8 ratio overnight)
- Tall 16-oz glass
- Reusable straw (the foam clings to disposable straws)
Instructions
- Pour cold brew and almond milk into the blender first. Cold liquid prevents the whey from clumping.
- Add the whey scoop, vanilla extract, MCT oil if using and the ice.
- Blend on high for 30 seconds until frothy and the ice is fully broken down. The shake should look creamy and uniform.
- Pour over fresh ice in a tall glass, dust with cinnamon and drink immediately. The crema fades after 5 minutes.
Macros Per Serving
Per 16 oz serving with MCT oil. Skip the oil to drop to 170 cal and 3g fat. Use whole milk instead of almond to add ~80 calories.
Substitutions & Variations
- Mocha: Use chocolate whey instead of vanilla. Add ½ tsp cocoa powder for depth.
- Caramel: Sub in salted caramel whey. Skip the cinnamon, dust with flaky salt.
- Dairy-free: Vanilla plant protein plus oat milk for extra creaminess.
- Pre-workout pump: Add an extra ½ scoop and skip the MCT. 40g+ protein, 175 cal.
- Frozen frappe: Add ½ frozen banana, blend longer. Adds 14g carbs.
Tips for Best Results
- Use cold liquid only. Hot coffee plus whey equals clumps and lost protein quality.
- If using a shaker (no blender), use isolate whey: it dissolves faster.
- For maximum froth, blend an extra 15 seconds at the end with just the lid air-vented.
- Brew cold brew in batch (1 cup grounds : 8 cups water, 18 hours fridge). 4 servings ready to go.
Which Protein Powder Works Best
Coffee-flavored whey is the killer pairing here, but vanilla and mocha both work. You want something that dissolves cold without clumps. See our best-value ranking for the cheapest options.
FAQ
Cold brew or espresso?
Cold brew is lower in acidity and blends smoother. If using espresso, pull 2 shots and top with ½ cup of water and chill briefly so hot coffee does not crash with cold whey.
Will the protein powder still mix if I just shake it in cold brew?
Yes for whey isolate (mixes smooth in a shaker bottle). Whey concentrate and blends may need a blender or a milk frother to avoid clumps. Mocha or vanilla flavors work best.
How much caffeine is in this?
About 150 to 200 mg, comparable to a strong cup of brewed coffee or one shot of espresso. Halve the cold brew if you are sensitive.
Can this replace breakfast?
It is more of a breakfast supplement than a full meal: 190 calories is light. Add a piece of fruit or a slice of toast to round it out. The 30g of protein keeps you full despite low calories.
What about pre-workout?
Excellent pre-workout option. Caffeine plus 30g of protein, low-fat, low-carb. Drink 30 minutes before lifting and you will feel it.
