Mister Donut Collabs With KOI To Launch Bubble Tea Doughnuts—Here’s A First Look

Mister Donut x KOI The has new bubble tea doughnuts

In an exciting first-ever collaboration, two iconic brands are joining forces to offer bubble tea fans a unique sweet treat: Mister Donut and KOI The have come together to create a special lineup of bubble tea doughnuts. This limited-time collaboration features two new doughnut flavours that are infused with KOI The’s signature Golden Bubble Milk Tea and their recently launched Roasted Oolong Tea. The series will be available till 30 November 2025, across all Mister Donut stores.

The two varieties, Pon De Ooolong and Golden BBT Cream, will cost $3 each. There will be limited quantities available each day, so we recommend you visit earlier in the day to avoid disappointment.

The Pon De Ooolong stars Mister Donut’s signature mochi doughnut with a creamy roasted tea filling, prepared with KOI The’s Taiwanese-grown Roasted Oolong tea leaves for an earthy and smoky finish. We liked how the cream tasted like genmaicha, a traditional Japanese green tea that’s blended with roasted brown rice. 

The Golden BBT Cream, on the other hand, features a soft yeast doughnut piped with milk tea-infused cream and chewy KOI golden bubbles. The dessert is finished with a drizzle of milk tea chocolate for extra tea flavour. While the combination was interesting, we wished there were more golden bubbles—the dessert lacked that satisfyingly chewy texture you’d expect from a cup of pearl milk tea.

For the complete experience, pair the new doughnuts with beverages from KOI’s new Roasted Oolong Tea series, which are said to be permanent items on the menu. There’s the Roasted Oolong Teh Gao (from $4.80), a twist on the traditional kopitiam-style tea, made with roasted oolong with condensed milk.

There’s also the Roasted Oolong Soya Gao (from $5.50), which features soya milk for a smooth and creamy finish.

To celebrate this collaboration, KOI The will offer a Buy-3-Get-3 Mister Donut voucher with a purchase of any two Roasted Oolong drinks. And for those looking to indulge even further, Mister Donut will roll out a 10-piece doughnut bundle deal that includes a free pre-loaded KOI gift card for 1-for-1 Roasted Oolong Teh Gao, along with one free Golden Bubble topping.

Even better, you can redeem a limited-edition sticker sheet with every purchase of two of the newly launched doughnuts, or any two Roasted Oolong drinks at KOI The.
