Starbucks just made it way easier to hit your protein goals without chugging another chalky shake. Starting September 29, 2025, Starbucks coffeehouses across the US and Canada will launch a brand-new protein line featuring Protein Cold Foam and Protein Lattes. That means your post-spin latte or iced cold brew can finally pull double duty as caffeine and protein for your muscles.
So, what is Starbucks Protein Cold Foam? Think of the classic frothy cold foam you already know and love, but blended with protein. When you add it to your favorite cold drink, you’ll tack on about 15 grams of protein per grande. Even better, it comes in flavors like banana, chocolate, vanilla (and sugar-free vanilla), salted caramel, matcha, and brown sugar. Seasonal flavors include pumpkin and pecan, because even your protein fix deserves a PSL moment.
Starbucks is also introducing Protein Lattes, crafted with the new Protein-boosted Milk. Each grande delivers about 27 – 36 grams of protein while keeping the same bold espresso flavor and creamy texture people expect from a latte. For anyone looking to combine their morning caffeine with a serious protein boost, these lattes make it easy to support muscle building without the hassle of a separate shake.
Now, let’s answer the real question: can you add protein to Starbucks drinks outside of these new menu items? The answer is yes. Starbucks is rolling out a new customization option with Protein-boosted Milk, letting customers upgrade everyday favorites like cappuccinos, macchiatos, or even seasonal drinks with an added protein kick. It’s a simple way to tailor your order for extra fuel without changing the flavor profile you already love.
So, when is Starbucks Protein Cold Foam dropping, and when are Starbucks protein drinks coming out? Both hit menus nationwide on September 29, 2025, and they’re sticking around for good. No limited test markets, no FOMO, this is a full rollout.
This move comes at the perfect time. According to the 2025 IFIC Food & Health Survey, protein is the top nutrient Americans are trying to add to their diets, with 70% of people saying they prioritize it daily. Starbucks’ new lineup makes it way easier to join the movement, no shaker bottle required.
So next time you’re heading home from the gym and wondering how to sneak in more protein, you don’t have to sacrifice your coffee run. Order your usual cold brew, latte, or refresher, then top it with Protein Cold Foam or swap in Protein-boosted Milk. Starbucks just made building muscle a little more delicious.
