Pulut hitam tastes like a healthy dessert because it is black rice, full of fibre and antioxidants, but bro that santan they drown it in is where 100 plus calories are hiding. The rice and sugar already put you around 190, then the coconut milk topping shoves you to 290.
It is not a bad dessert at all. You actually get some fibre and a bit of protein out of it. Just respect that it is a 290 calorie bowl and not the free health food it pretends to be. If you want it lighter, the move is simply less santan on top.
