Ingredients & Equipment

For a drink like this, the ingredients really matter because there are only a few, and each one has a strong impact on the flavor, texture, and look.

The butterfly pea flowers are what give the tea its deep blue color and subtle earthy flavor. You’ll want to choose dried (or fresh) petals that are vibrant and bright rather than dull. Freshly dried flowers will brew a stronger color and a cleaner taste.

If the flowers look faded, the tea will come out weak and grayish instead of that striking indigo shade that makes this drink special.

Milk is another important ingredient, since it becomes the cold foam. Whole milk gives the creamiest, most stable foam, but you can absolutely use oat milk, almond, or soy milk if you prefer.

If you go with a non-dairy option, look for a barista blend: those are formulated to froth well. The milk should be ice cold before you froth it; otherwise, the foam will collapse quickly.

Vanilla syrup ties the drink together with sweetness and flavor. Store-bought syrups are convenient, but homemade works just as well if you make a simple syrup and add a touch of vanilla extract.

You can adjust the sweetness depending on your taste—just enough to complement the floral tea without overpowering it.

As for equipment, you don’t need anything complicated.

A small kettle or pot to heat water is essential, and a strainer helps separate the flowers once they’ve steeped.

For the cold foam, a hand blender is the easiest tool, but a handheld frother, French press, or even a tightly sealed jar you can shake will do the job.

Finally, use a tall, clear glass with plenty of ice—this keeps the drink cold and shows off the dramatic blue tea and fluffy white foam on top.

Ingredients for 1 large serving:

• 1 tbsp dried butterfly pea flowers
• 1 cup hot water
• ⅓ cup ice-cold whole milk (any milk works)
• 1 tbsp vanilla syrup (sweeten to taste)
• Ice

How to Make an Iced Blue Tea Latte

Instructions:

1. Brew the blue tea: Steep the butterfly pea flowers in hot water for 5–7 minutes until it’s a deep, inky blue. Strain and let it cool.
2. Make the vanilla cold foam: Blend the cold milk and vanilla syrup for about 10 seconds—just until thick and silky. (No blender? Use a handheld frother or shake it hard in a jar.)
3. Build the latte: Fill a tall glass with ice. Pour in the blue tea. Slowly spoon or pour the vanilla foam over the top for that clean, layered look.
4. Drink your art: Keep the layers for the wow factor, or give it a gentle swirl before sipping. Refreshing, lightly floral, and just sweet enough!

Additional Tips & Variations

• Add citrus for a color change: A squeeze of lemon or lime will shift the blue tea into a gorgeous purple or pink hue. Fun for presentation and adds a tangy twist!
• Turn it into a layered drink: Pour the tea first, then carefully layer cold milk (before foaming) for a striking two-tone effect, finishing with foam on top.
• Serve it warm: Skip the ice and cold foam, and instead steam the milk with vanilla for a cozy hot latte.
• Top with edible flowers: Garnish with dried butterfly pea petals, violets, or lavender buds for a café-style presentation.
• Mix with matcha: Create a blue-and-green layered latte by brewing matcha separately and carefully pouring it over the butterfly pea tea before adding foam.
• Make a dessert version: Use sweetened condensed milk instead of vanilla syrup for a richer, creamier, almost Thai-tea-style drink.
