Iced Blue Coconut Matcha (Starbucks Copycat)

This Iced Blue Coconut Matcha is the stunning Starbucks copycat recipe you're going to want to make on repeat all summer long. We're talking a creamy, earthy matcha base topped with the most gorgeous blue coconut cold foam you've ever seen — and it's ready in just 5 minutes.

If you've seen this drink floating around on TikTok and Instagram lately, you already know it's one of the most visually striking things Starbucks has ever put on the menu. That dreamy blue foam sitting on top of a bright green mango matcha? It's almost too pretty to drink. Almost.

The secret behind the blue color is blue spirulina powder — a natural, tasteless pigment that gives the cold foam its jaw-dropping hue without changing the flavor at all. It's completely safe, packed with nutrients, and honestly just really fun to work with.

This homemade copycat Starbucks blue coconut matcha costs a fraction of the Starbucks price and tastes just as incredible. Five minutes, one milk frother, and you've got the new Starbucks summer drink right in your own kitchen. Let's make it!

What does the Blue Coconut Matcha taste like?

This drink is earthy, tropical, creamy, and refreshing all at once — it's genuinely unlike anything else in the Starbucks lineup. The matcha base is smooth, with the mango syrup adding a sweet, tropical twist that balances the earthiness perfectly.

The blue coconut cold foam on top is silky, lightly sweet, and coconutty — it slowly melts into the matcha as you drink, making every sip a little different. And the blue spirulina? Virtually tasteless. It's purely there to make this drink look absolutely stunning.

Why You'll Love This Copycat Blue Coconut Matcha

• Ready in 5 minutes — Faster than any drive-through line, and so much more satisfying to make yourself.
• That blue coconut cold foam though — It's silky, coconutty, and the most beautiful shade of blue. Once you make it, you'll want to put it on everything!

What is Blue Spirulina?

If you've never cooked or baked with blue spirulina before, you're in for a treat — and not just because of the color. Blue spirulina is a natural pigment derived from blue-green algae, and it's the ingredient responsible for that stunning, electric blue hue in the cold foam.

Here's the best part: it tastes like virtually nothing. Unlike green spirulina, which has a strong, earthy flavor, blue spirulina is almost completely neutral. It's purely a color agent, which means you get all the visual drama without any funky taste.

It's also completely safe and commonly used as a natural food coloring in everything from smoothie bowls to lattes. You can find it at most health food stores, on Amazon, or at Whole Foods — and a little goes a very long way!

Ingredients

This blue coconut matcha comes together with two components — the iced matcha base and the blue coconut cold foam. Here's what you'll need!

• Heavy cream and whole milk — Together they give the cold foam its rich, silky, pourable texture.
• Coconut syrup — Adds that sweet, tropical coconut flavor that makes this cold foam so irresistible.
• Blue spirulina powder — Just ⅛ teaspoon is all you need for that gorgeous, vibrant blue color!
• Pure matcha powder — The earthy, vibrant green base of this drink. Always sift it before whisking to avoid clumps!
• Milk of choice — Any milk works beautifully here. The recipe uses 2%, but oat milk or coconut milk take the tropical vibes up a notch!
• Mango syrup — The tropical twist that makes this drink taste like a vacation.

Ingredient Substitutions

• Dairy-Free: Swap the heavy cream and whole milk in the cold foam for full-fat coconut cream and oat milk. It'll still be creamy, dreamy, and delicious!
• No mango syrup? Vanilla syrup works great as a more subtle alternative, or try passion fruit syrup for a different kind of tropical twist.
• Matcha powder: Always use pure ceremonial grade matcha for the best flavor and the most vibrant green color. Culinary grade works too, but the flavor won't be quite as smooth.
• Coconut syrup: No problem! Use 1½ tablespoons of vanilla syrup and ⅛ teaspoon of coconut extract instead for that same sweet coconut flavor.

How to Make Iced Blue Coconut Matcha

This drink comes together in four easy steps — and the hardest part is not drinking the blue coconut cold foam straight from the jar!

• Step 1 — Make the cold foam. Add the heavy cream, coconut syrup, whole milk, and blue spirulina powder to a small glass or jar. Froth with a milk frother for 20-30 seconds until foamy and well combined. Set aside.
• Step 2 — Make the matcha. Add the water to a small microwave-safe jar or glass and heat until boiling — about 30-45 seconds in the microwave. Sift the matcha powder into the hot water to remove any large clumps, then whisk together until smooth and slightly foamy. Set aside.
• Step 3 — Build the drink. Add ice to a tall glass, then pour in the milk and mango syrup. Stir to combine, then pour the matcha over the top and stir again.
• Step 4 — Spoon the blue coconut cold foam over the matcha and drink up!

Tips for the Best Blue Coconut Matcha

• Always sift your matcha. This is non-negotiable! Matcha clumps easily, and sifting before whisking gives you a perfectly smooth, lump-free concentrate every single time.
• Use a matcha whisk. A milk frother works in a pinch, but a traditional matcha whisk gives you the smoothest, most evenly dissolved matcha.
• Don't skip the mango syrup. The earthiness of the matcha needs that sweet, fruity contrast. The mango syrup is what makes this drink taste tropical and balanced!
• Froth the cold foam for exactly 20-30 seconds. Under-froth and it'll be too thin. Over-froth and it gets too stiff to pour. The sweet spot is right in that window.
• Use ceremonial grade matcha. The higher quality the matcha, the smoother and more vibrant green your drink will be. It's worth the upgrade!
• Serve immediately. The blue foam is most vibrant and beautiful right after frothing. Don't let it sit too long before drinking!
