Fill a large pot halfway with water and bring to a boil. If desired, add ~10 drops liquid sweetener to infuse some sweetness. (I like to use stevia or monk fruit drops.)
Add uncooked tapioca pearls to boiling water. Lightly stir unto boba begin to float, then cover and boil for 3 minutes.
Remove pot from heat and carefully drain boba pearls. Transfer to a bowl and cover with water until ready to use. (Otherwise they’ll stick together!)
In a blender, combine frozen banana, coconut cream, and coconut milk and blend until smooth.
Add cooked tapioca pearls to boba tea cups, pour in blended milk tea, serve with a boba straw, and enjoy!
