Starbucks is Testing Protein Cold Foam — Here’s What We Know
Starbucks is officially stepping into the functional fuel space with the launch of a new Protein Cold Foam currently being tested at five select U.S. locations. This move could be a game-changer for people who want more than just caffeine in their cup. Here’s everything you need to know about the pilot product and why it matters for you!
The Backstory
Starbucks calls it part of their “Starting Five” test menu — and the Protein Cold Foam leads the lineup. It’s available in a banana flavor, served as a topping on any iced espresso drink, and promises a smooth, clump-free texture. The goal? Add 15–18 grams of protein to your coffee without chalkiness, extra prep, or a shaker bottle.
CEO Laxman Narasimhan has acknowledged a shift in consumer habits, including customers bringing their own protein to Starbucks. The company is aiming to provide a better, more integrated option.
What’s in the Foam?
Here’s what we know so far:
15–18g of protein per serving
Banana flavor (for now)
Unsweetened cold foam base
A proprietary protein blend developed by Starbucks to avoid the clumping or gritty texture common with protein powders
However, Starbucks has not revealed the source of the protein. It remains unclear if it’s whey, casein, collagen, plant-based, or a custom blend which (to us) is a big red flag. All we know is that it’s formulated to dissolve smoothly and blend seamlessly into the drink. Hopefully, if they move this into the market they will be more transparent with the blend.
Why It Matters
This isn’t just a gimmick — it’s a response to consumer demand for functional fuel that aligns with fitness and performance goals. For athletes, high-performers, or anyone tracking macros, this could be a welcome addition to their daily caffeine ritual.
Convenient protein without needing to bring your own
Supports morning fueling and recovery
Encourages smarter snacking habits vs. under-fueled routines
If the test proves successful, Starbucks may roll out the Protein Cold Foam nationwide in the coming months.
Powerhouse Take
This could be a win for on-the-go fueling if Starbucks keeps the formula clean, the ingredients transparent, and the flavors expanding. But until we know the exact protein source, it’s hard to fully evaluate how it fits into a performance nutrition plan.
Still, it signals something big: mainstream coffee culture is waking up to protein. And if done right, that’s a trend we can get behind.
