1. Make The Boba: Pour two cups of water into a saucepan and bring to a boil. Then, add the tapioca pearls and boil for five minutes (until the pearls are all floating to the top).
3. Assemble The Coffee Boba: Scoop boba into a serving glass. Then, add ice on top of the boba. Next, pour oat milk over the ice, followed by the coffee.
