Other variations may add ingredients such as pumpkins, sweet potatoes, jackfruit, plantains, cassava, rice balls, tapioca pearls, and kolang-kaling (aren palm fruit).

Kolak is basically a dessert based on a sweet liquid made from the mixture of palm sugar and coconut milk.

Blocks of palm sugar are crushed and liquified in boiling water, mixed together with coconut milk and pandanus leaf to add aroma.

However, some variant might add ice cubes as sweet cold dessert according to individual preferences.

Sometimes a combo is presented in a serving, for example kolak pisang that contains slices of banana is often combined with diced sweet potato and kolang-kaling sugar palm fruit.
