Method
- Combine water, palm sugar, white sugar, pandan leaves and salt in a heavy pot. Bring to a simmer; stir until the sugars dissolve completely. The base should be a fragrant amber syrup.
- Add cubed sweet potato. Simmer 12 minutes until the potato is just tender enough to pierce with a fork but still holding shape — overcooked, they break and turn the syrup muddy.
- Slice bananas diagonally into 2cm pieces. Add to the pot along with kolang kaling if using. Simmer 5 minutes; the bananas will soften and turn from pale to translucent gold.
- Pour in the coconut milk slowly while stirring. Bring to just below a simmer — never boiling, which splits the coconut. Cook 4 minutes; the syrup turns from clear amber to creamy cappuccino.
- Discard the pandan leaves. Taste — the dish should be subtly sweet, with the salt lifting the palm sugar's deeper notes.
- Ladle into small bowls. Serve warm or at room temperature; in the tropics, kolak is sometimes served chilled. During Ramadan, kolak is the first thing eaten at iftar — its gentle sweetness and warmth are a cultural signal that the fast has ended.
Common questions

How hard is Kolak Pisang to make at home?
Kolak Pisang is approachable for a home cook with basic stove skills — total time about 35 minutes, no special technique required.
Can Kolak Pisang be scaled up or down?
This recipe is written for 6 servings. To scale, multiply each ingredient proportionally; the cooking times stay the same up to about double the volume. Beyond that, expect to cook in batches because of pan size and heat distribution.
Cultural Note
Kolak is the Ramadan dessert of Indonesia — every household makes it during the fasting month for the iftar (sunset breaking-fast meal). The standard kolak pisang ubi (banana and sweet potato) is universal; regional variants add pumpkin (kolak labu), jackfruit (kolak nangka), or the chewy palm fruit kolang kaling. The pandan-coconut-palm sugar combination is the foundation of countless Indonesian desserts; kolak is the simplest expression. The dish's gentleness is intentional — after a day's fasting, harsh flavours are unwelcome.
