On a separate pan over medium heat, dissolve the brown sugar in the coconut milk, let it boil until thick. Add the cooked rice and mix until very thick consistency. Place the banana leaves at the bottom of the 'bilao' or a big rounded plate and brush with oil, spread the sticky sweet rice on the leaves and flatten evenly. Toppings is 'latik' (optional) - a stir fried coconut milk cooked until oils secretes and dries up leaving a golden brown coconut flakes.
