Ingredients & Substitutions
- Protein Powder: Chocolate flavored protein powder works best for this drink, but you can experiment with different flavors as well. Both whey and vegan protein powder work for this recipe. Most importantly, choose a powder that you like the flavor of as you can slightly taste the protein powder.
- Coffee: Use either chilled coffee, or homemade cold brew coffee that you have prepared in advance. You can also buy cold brew coffee ready-made to save time.
- Milk: Use 2% milk. For a vegan version, use almond milk or oat milk instead.
- Chocolate syrup: The homemade chocolate syrup is made with cocoa powder, granulated sugar and water. If you want, you can replace this with a store bought coffee syrup, but it may have a slightly artificial flavor.
- A whisk to whisk together the chocolate syrup ingredients.
- A small saucepan to make the chocolate syrup in.
- Optionally, serve the drink in iced coffee tumbler cups.
Step 1: Whisk the cocoa powder, granulated sugar and water together in a small bowl.
Step 2: Add the mixture to a saucepan and heat the syrup on medium heat for 5 to 10 minutes, stirring constantly. Once the sugar has fully dissolved, remove the syrup from the stove and set aside.
Step 3: Mix the protein powder, coffee and syrup together until the protein powder is fully mixed into the coffee.
Step 4: Pour the protein coffee over a glass filled with iced.
Step 5: Add the milk on top of the protein iced coffee. Stir and enjoy!
This iced coffee is best served fresh, however you can prepare and store the chocolate syrup in advance.
After making the chocolate syrup, let it cool to room temperature before storing it in an airtight container in the fridge for up to 1 to 2 weeks. The chocolate syrup recipe makes about ¾ cup of syrup, which will leave some leftovers.
- Mix the protein powder into the coffee before adding ice. It is easiest to dissolve the protein powder in the coffee and chocolate syrup before adding ice. If there is already ice in the glass, the protein powder may clump up.
- Don’t let the chocolate syrup boil. When making the syrup, don’t let it fully boil. Adjust the temperature as needed to maintain a very gentle simmer. Boiling the syrup can make it too thick.
- Freeze coffee in ice cubes. To prevent your iced coffee from becoming watered down, freeze chilled coffee in an ice cube tray and use coffee ice cubes instead of regular ones.
- Extra Protein: For an extra high protein coffee, double or triple the amount of protein powder added. Note that this will add a stronger protein flavor. To compensate, you can add a bit of extra chocolate syrup.
- Vegan: To make this drink vegan, use a vegan protein powder and almond milk instead of cow’s milk.
- Vanilla: For a vanilla flavored drink, use vanilla protein powder and vanilla flavored almond milk.
- Iced Protein Latte: To make this drink a latte instead of iced coffee, use the “cold froth” option on an electric frother to froth the cold milk. Pour it on top of your drink.
To turn this into a coffee protein shake, add all the ingredients in a blender with a handful of ice until smooth. For extra creaminess, add in a banana as well. If needed, adjust the amount of almond milk and coffee to get the right consistency.
You can slightly taste the protein powder, but it is subtle. If you really don’t like the taste, add extra chocolate syrup to cover the taste completely.
Yes. However, make sure that the syrup is a simple syrup that is meant to be used for drinks. Store bought syrups may have a more artificial flavor than homemade ones.
