I’ve been wanting to make a cocktail using butterfly pea flowers ever since my daughter bought some to add to her smoothies and make tea.

Once I saw the vibrant blue color and learned that it was color-changing, I was intrigued! Plus, it has incredible health benefits.

5 Top Benefits of Butterfly Pea Flower

  1. Rich in Antioxidants
    Butterfly pea flowers are loaded with antioxidants, especially anthocyanins, which help fight free radicals and reduce oxidative stress.
  2. Supports Brain Health
    Traditionally used in Thai medicine, butterfly pea is believed to enhance memory and support cognitive function.
  3. Natural Mood Booster
    Compounds in the flower may help reduce stress and anxiety, promoting a calm, focused mind.
  4. Anti-Inflammatory Properties
    It has natural anti-inflammatory effects, which can aid in reducing internal inflammation and supporting overall wellness.
  5. Promotes Healthy Skin and Hair
    Thanks to its high flavonoid content, butterfly pea flower can support collagen production, helping to maintain youthful skin and strong hair.

There are so many cool drinks you can make using butterfly pea flowers. The base for this cocktail is a simple syrup that can be made ahead of time and kept in the refrigerator for easy prep.

I also have a margarita recipe to share soon and it’s purple.

This is the exact brand of butterfly pea flowers that I used.

Let’s get to it!

INGREDIENTS YOU NEED TO MAKE THE BUTTERFLY PEA FLOWER COCKTAIL

You only need a few simple ingredients to make this cocktail. (the exact measurements, nutritional information and full recipe are in the printable recipe card at the bottom of the post).

  • Butterfly Pea Flowers – you can also check out the health food store
  • Prosecco – Use your favorite brand. You don’t have to use top-shelf, however, I do recommend a mid-line brand. I’m a fan of LaMarca Prosecco.
  • Vodka – use your favorite brand. Can also use a flavored vodka such as lemon.
  • Sugar and Water
  • Lemons – to change the color of the tea and for garnish.
  • Blueberries and Raspberries – optional, but they definitely add to the aesthetic!

How to Make a Butterfly Pea Flower Simple Syrup for Cocktails

Boil Water and Sugar – Add 1 cup of sugar and 1 cup of water to a pot over medium high heat.

Remove the tea ball or strain if pea flowers were added directly to the water. Let cool.

Add Butterfly Pea Flowers – Add 1 tbsp of butterfly pea flowers in a mesh tea ball strainer.

This strainer works wonderfully. However, you can also add the flowers directly to the boiling water and sugar mixture.

You will just need to strain it before adding it to your cocktail.

Bring to a quick boil, but turn it down to low immediately. Be sure not to let it boil as it will evaporate and alter the sweetness.

Let it Steep – Let infuse on low for 3-5 mins. It will turn bright blue! The longer you steep, the deeper the blue color will be. 

This is the exact glass teapot I bought for my daughter for her infused tea. It includes 2 blooming tea flowers.

It only takes a few minutes for the butterfly pea flowers to change the color of the boiled water to a beautiful blue color. It really is cool to see how fast it changes.

To achieve the vibrant purple color, add fresh lemon juice.

You will see the color-changing effect almost immediately. Again, the longer it steeps, the more vibrant it gets.

Place in Sealed Bottle – Pour the simple syrup into a clean bottle or jar to store.

Color-changing cocktails – Use the butterfly pea flower simple syrup in cocktails with acidic mixers like lemon juice, lime juice, or even ginger beer for a stunning color-changing effect.

What are butterfly pea flowers?

Butterfly pea flowers are vibrant blue blossoms, native to Southeast Asia. They’re often used in teas, cocktails, and natural dyes due to their stunning color and health benefits.

What do butterfly pea flowers taste like?

They have a very mild, earthy flavor—slightly woody or grassy—making them perfect for blending into teas, lemonades, or cocktails without overpowering other ingredients.

Why do butterfly pea flowers change color?

The flowers contain natural pigments called anthocyanins that react to pH. Add something acidic (like lemon juice) and they transform from deep blue to purple or pink!

How do you store butterfly pea flower tea for cocktails?

To keep it fresh and vibrant, store brewed butterfly pea flower tea in an airtight container in the refrigerator for up to 5–7 days. For longer storage, you can also freeze it in ice cube trays—perfect for tossing into cocktails for an extra pop of color and chill.
If you’re storing dried butterfly pea flowers, keep them in a cool, dark place in an airtight container—they’ll last for up to a year.
