Keto-friendly tapioca pearls are made from gelatin, tea, and oil. A half cup of keto tapioca pearls made this way contains under 0 grams of net carbs. Essentially, gelatin is combined with hot water and left to set. The gelatin is then sucked into a dropper, and tiny gelatin boba pearls are dropped into very cold oil, creating ketogenic boba.

4 Ways to Lessen the Sugar Content in Bubble Tea

Bubble tea is typically high in sugar. Here are a few ways to lower the sugar content in your bubble tea or make it sugar-free!

  1. Order sugar-free bubble tea, or ask for 25% sweetness.
  2. Request (or use) a keto sugar substitute, like stevia, erythritol, or monk fruit.
  3. Skip the boba pearls, ask for sugar-free jellies instead.
  4. Choose sugar-free toppings, like sugar-free whipped cream made from heavy cream.

Does Keto-Friendly Boba Taste as Good as Regular Boba Tea?

Keto bubble tea still tastes like sweetened boba milk tea. The most significant change would be in the low-carb, sugar-free boba pearls. Instead of tasting chewy and starchy, they’ll taste like sweetened gelatin.

Keto sweeteners taste slightly different than regular sugar. If you’re not used to them, you may notice the difference. However, keto boba tea still tastes sweet and delicious.
