I first discovered ube at Mitchell's Ice Cream in San Francisco — their ube ice cream was something I still think about. So when I stumbled upon ube powder and extract a few years later, I immediately got to work bringing ube back into my life. Ube Pancakes, Ube Brownies, and this purple boba tea were all on the docket — and honestly this ube tea might be the one I make most often.
This purple boba drink is everything I want in a boba order — creamy ube milk tea with that distinctive sweet, nutty, subtly vanilla-like purple boba flavor, loaded with chewy tapioca pearls at the bottom. It's one of the most popular ube drinks you can make at home: vibrant, customizable, and significantly cheaper than a $9 cup from the bubble tea shop. The whole thing comes together in about 25 minutes with a handful of simple ingredients.

What Is Purple Boba?
Purple boba (also called ube boba, ube milk tea, or purple bubble tea) is a sweet milk tea drink flavored with ube — a Filipino purple yam — and loaded with chewy tapioca pearls. The distinctive purple boba flavor comes from ube extract: sweet, nutty, and subtly vanilla-like, with a rich purple-lavender color that makes it one of the most visually striking drinks you can make at home.
Boba pearls (affiliate link; also called tapioca pearls or bubbles) are made from tapioca starch, usually purchased dry, then boiled and sweetened with simple syrup before being added to the bottom of the drink. The result is a chewy, sweet contrast to the creamy milk tea.
What Is the Difference Between Taro and Ube?
Taro and ube are both starchy root vegetables used in extract or powdered form to flavor purple drinks and baked goods — and they're often confused for each other.
The key differences:
- Color: Ube is a rich, deep purple when harvested. Taro is white or pale with purple flecks — much lighter in color, and produces a more lavender-toned drink.
- Flavor: Both have a nutty flavor, but ube also has distinctive vanilla notes that make it sweeter and more complex. Taro is earthier and more savory in comparison.
- Ube boba vs. taro boba: Ube boba will be deeper purple and sweeter. Taro boba is lighter in color and has a more pronounced earthy nuttiness. Some bubble tea shops combine both — if you see "ube taro" on a menu, expect a blend of both flavors.
Important Ingredients and Substitutions
Ube extract — The star of this recipe. Ube extract is made from purple yam and is available online (Amazon—affiliate link) and at Asian grocery stores. A little goes a long way — start with ¼ teaspoon per glass and adjust to taste. Ube powder also works; use about 1 teaspoon per glass and whisk well.
Boba pearls — Black tapioca pearls are the classic choice and easiest to find. Mini boba pearls, clear pearls, and colored pearls all work — just follow the package directions for cook time since they vary significantly by brand. Boba pearls are available online (Amazon—affiliate link) and at specialty Asian markets.
Tea — Black or green tea is great. Earl Grey adds a bergamot floral note that pairs beautifully with ube. Jasmine green tea is another excellent choice. White tea gives a more delicate, subtle tea flavor. Whatever you use, brew it strong.
Milk — Any milk works. Dairy milk gives the creamiest result; oat milk adds a natural sweetness; coconut milk adds a tropical richness that pairs well with ube. If using sweetened plant milk, reduce the simple syrup accordingly
How to Cook Boba Pearls
Getting the boba right is the key to a great purple boba drink. Here's everything you need to know:
|
Cooking Time |
Most dried boba pearls cook in 5–10 minutes in boiling water. Follow your package directions — times vary significantly by brand and pearl size. They're done when they float to the surface and are tender all the way through with a soft, slightly chewy center. |
|
How to Know They're Done |
Scoop one out and bite it. It should be soft and chewy throughout — not hard in the center, not mushy on the outside. If it's still firm in the middle, give it another 2 minutes. |
|
How to Prevent Sticking |
Stir the pearls immediately after adding them to the boiling water, and stir occasionally during cooking. Once drained, transfer directly to the simple syrup — don't let them sit dry or they'll stick together. |
|
Instant Boba |
If you want to skip the cooking step, instant boba (the kind that comes with flavored syrup in a cup) is a great shortcut. Just follow the package instructions — most only require a quick soak in hot water. |
|
Storing Leftover Cooked Boba |
Best used within 4 hours. If storing longer, keep in simple syrup in the refrigerator for up to 2–3 days. The pearls will firm up slightly but are still good. |
Recipe Variations
This purple boba tea is delicious as written, but easy to riff on:
- Lavender Ube — Add a few drops of lavender extract to the simple syrup before soaking the boba for a floral twist on the classic purple bubble tea.
- Whipped Cream Top — Finish each glass with a swirl of whipped cream for a more indulgent, café-style presentation.
- Ube Taro — Add a small amount of taro powder alongside the ube extract for a nuttier, more complex flavor profile — like the hybrid drinks you see on bubble tea menus.
- Mini Boba — Swap regular boba for mini tapioca pearls (affiliate link) for a fun variation — they float more and distribute through the drink differently.
- Hot Ube Tea — Skip the ice and boba and simply stir ube extract into brewed black or green tea with warmed milk and simple syrup to taste for a cozy ube tea latte.
How to Make Purple Boba Tea (Ube Milk Tea)
For the complete recipe and measurements, scroll to the recipe card at the bottom of this post.
Prepare: Cook the boba according to package directions.
Step 1: Cook the boba according to package directions.
Step 2: Stir the drained boba into the simple syrup. Let sit for 10–15 minutes.
Step 3: Brew the tea in 1 cup of hot water according to package instructions. Let cool slightly.
Step 4: Divide the boba and as much simple syrup as desired between two large glasses. Add half the tea and ¼ teaspoon ube extract to each glass. Stir well until the ube is fully incorporated and the tea turns purple.
Step 5: Add a large handful of ice to each glass.
Step 6: Divide the milk between the two glasses. Taste and add more simple syrup if desired. Serve with boba straws.
Chelsea's Recipe Pro-Tips
- Brew tea in a measuring cup — Using a glass measuring cup makes it easy to pour precise amounts into each glass without spills. Follow your tea package for water temperature and steeping time — green and white teas steep at lower temperatures than black tea.
- Don't skip the simple syrup soak — Ten minutes minimum. The boba absorbs the sweetness during this time, transforming plain tapioca pearls into the sweet, glossy bubbles that make boba so good. Skip it and they'll taste like plain starch.
- Use a clear glass — The deep purple-lavender color of ube milk tea against the black boba is genuinely beautiful. Part of the joy of making this at home is showing it off.
- Adjust the ube to taste — Start with ¼ teaspoon per glass and taste before adding more. Ube extract varies in strength by brand — some are very potent, others more subtle.
- Boba straws are non-negotiable — Regular straws are too narrow for the tapioca pearls. Wide boba straws (sometimes called smoothie straws—affiliate link) are easy to find online and completely transform the drinking experience.
- Make it your own sweetness level — The nice thing about making purple boba at home is you control the sugar. Start with less simple syrup than you think you need and add more to taste. Store-bought boba is almost always sweeter than homemade.
Storage Directions
- Refrigerating: Purple boba tea is best enjoyed fresh — within 4 hours of making it. The tapioca pearls get tough and gummy when refrigerated in the drink. If you have leftover cooked boba, store it separately in the simple syrup in a sealed container in the refrigerator for up to 2–3 days.
- Freezing: Does not freeze well — the boba texture suffers significantly when frozen.
- Make-ahead tip: You can brew the tea ahead and refrigerate it. The simple syrup can also be made ahead of time and stored separately in the fridge. Boba must always be cooked fresh. Heat the simple syrup before adding the boba to soak.
Serving Suggestions
Purple boba tea is a fantastic standalone treat any time of day — it's essentially dessert in a glass. For a snack or movie night spread, pair it with Lemon Blueberry Bread or Kodiak Protein Muffins.
Purple Boba FAQs
Purple boba has a sweet, creamy, nutty flavor with subtle vanilla notes — it's the distinctive ube flavor that makes it stand out from other boba drinks. The tapioca pearls add a chewy sweetness, and the whole drink is creamy and refreshing. It's less earthy than taro boba and sweeter overall.
Purple boba is flavored with ube (a Filipino purple yam) and has a deeper purple color, sweeter flavor, and more pronounced vanilla notes. Taro boba uses taro root powder and is lighter in color (more lavender) with an earthier, nuttier flavor. Some shops offer a blend of both.
Ube extract is available on Amazon (affiliate link), at Asian grocery stores, and at some specialty food stores. The most widely available brand online is Butterfly brand ube extract — a small bottle goes a long way since you only need ¼–½ teaspoon per drink.
Yes — no blender needed at all for this recipe. Just stir the ube extract into the tea directly in the glass. It mixes in easily with a spoon or straw.
Cooked boba is best within 4 hours of making. In simple syrup in the refrigerator, they keep for 2–3 days, but will firm up. Dry (uncooked) boba pearls keep for months in a sealed container at room temperature.
Yes — just use any plant-based milk. Oat milk, coconut milk, and almond milk all work well. If using sweetened plant milk, reduce the amount of simple syrup so it doesn't get too sweet.
