Bika ambon or golden cake or golden kuih bingka, is an Indonesian dessert made from ingredients such as tapioca flour, eggs, sugar, yeast and coconut milk. Bika ambon is generally sold in kaffir lime or pandan flavor, but today it is also available in other flavors like banana, durian, cheese and chocolate.
Originating from the city of Medan in North Sumatra, the cake is usually cooked twelve hours. This is thought to ensure that it lasts longer. After four days the cake starts to harden.
