For brown sugar bananas, combine brown sugar and coconut milk in a frying pan and stir over medium-high heat until milk starts to boil and sugar dissolves (2-3 minutes). Add banana and cook, turning occasionally, until caramelised and just tender (3-4 minutes). Stir in lime juice and keep warm.
Combine milk, coconut milk, sugar, kaffir lime leaves, vanilla bean and seeds in a saucepan and bring just to the simmer over medium heat, stirring to dissolve sugar. Drain tapioca, add to milk mixture and stir continuously until thick and tapioca is tender and translucent (4-5 minutes). Remove from heat and serve immediately with brown sugar bananas and drizzled with extra coconut milk.
