Ingredients and Substitutions

Butterfly pea powder: Sift before using to avoid clumps.
- You can also use dried butterfly pea flowers, similar to how I use them in my blue butterfly pea rice recipe. You will simply steep the flowers in hot water for about 5 minutes, so think of it as making a blue pea flower tea!
Hot water: Helps dissolve the powder.
- Unlike when making your regular matcha latte, where you have to use warm water (instead of hot) to dissolve the matcha powder, it’s easier to use hot water here to help dissolve the blue pea powder better.
Plant-based milk: Any kind works. Oat, soy, almond, rice, coconut, you name it!.

Optional Add-Ins:
Ice cubes: Use if making an iced version.
Agave or maple syrup: Any liquid sweetener works. They also pair great with my lavender simple syrup!
Vanilla extract: Optional flavor boost, similar to my vanilla matcha latte recipe.

Top Tips

Sift the powder: Butterfly pea powder clumps easily, so try not to skip the sifting part so you can get a smooth mermaid latte!
Use hot (boiling) water to dissolve: Unlike regular matcha, which burns in hot water, butterfly pea powder actually dissolves better with hot water. So no need to hold back the heat here!

Pair this with a nutritious plant-based breakfast, such as these matcha overnight oats, yogurt granola cups, or flaxseed pudding (with 3 variations)!

This blue latte is, of course, also great with any main dishes you can think of, or on its own as a refreshing, caffeine-free midday drink!

FAQ

Blue matcha is made from finely ground butterfly pea flowers, so it is entirely different from the regular matcha. Which is why the name is a little bit misleading.

Other than the difference in color, it might look like matcha, but it contains no caffeine (source: Healthline). It’s mostly used for its natural blue color.

A blue latte typically includes butterfly pea powder, hot water, and milk. You can also add sweetener for extra flavor, and it can be served hot or iced.
