Ingredients you’ll need:

Heavy cream – Creates the silky, café-style foam texture.

Unflavored protein powder – Adds a creamy boost of protein without altering the flavor.
Cocoa powder – Gives the foam its deep chocolate flavor.
Maple syrup – Naturally sweetens the foam without refined sugar.

How to make chocolate protein cold foam:

(The full written and printable recipe is further below.)

Step #1) Add the cocoa powder and protein powder to a small pitcher or measuring cup.

Step #2) Add the cream, milk, and maple syrup.

Step #3) Use a handheld frother or whisk until the mixture becomes creamy and airy.

Step #4) Pour over iced coffee, cold brew, or iced shaken espresso.

🌟 Expert tips:

Use a fine-textured protein powder: Some protein powders can clump easily—choose one that dissolves well in liquids or sift it before mixing.
Froth temperature matters: For the best foam, use cold ingredients straight from the fridge—warm cream doesn’t whip as well.
Extra flavor boost: Stir in a dash of vanilla or a pinch of salt to balance the chocolate flavor.

Delicious variations:

Mocha cold foam: ☕️ Stir in a pinch (⅛–¼ teaspoon) of instant espresso powder for a stronger coffee-chocolate flavor.
Cinnamon chocolate: 🪵 Add ⅛ teaspoon ground cinnamon for a warm, cozy twist.
Peppermint chocolate: 🍃 Mix in a drop of peppermint extract for a refreshing holiday version.
Caramel chocolate: 🍯 Drizzle a little sugar-free caramel syrup on top or add a touch of caramel extract for a Starbucks-style treat.
Vegan version: 🥥 Use coconut cream and oat or almond milk, plus a plant-based protein powder.

Storing & make-ahead instructions:

Make ahead: You can mix all the ingredients together up to 1 day in advance and keep them in a sealed jar or airtight container in the fridge. When ready to use, simply froth, whisk, or shake the mixture until thick and foamy.
Storing leftovers: If you have any leftover foam, store it in the refrigerator for up to 24 hours. The foam may deflate slightly as it sits, so give it a quick whisk or froth again before serving.

Recipe FAQs:

Can I use flavored protein powder instead of unflavored?

Absolutely! Chocolate or vanilla protein powder both work great. Reduce the cocoa powder to 1/2 Tbsp if using chocolate protein powder.

Do I need a frother to make this?

Nope! A handheld frother is the easiest, but you can also use a whisk or shake everything in a tightly sealed jar for 30–60 seconds until foamy.

Can I use this on hot coffee?

You can, but it works best on iced or cold brew coffee, since the foam holds its texture longer on cold drinks.

What’s the best protein powder to use?

Any unflavored or mild-tasting whey, collagen, or plant-based protein powder works.
