Bika ambon

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. This cake is a further development of kue bingka, a famous traditional cake in the eastern parts of Indonesia. The cake is notable for its sponge-like holes, which are formed by yeast in the cake dough that creates bubbles. These holes give it a unique spongy texture when it is baked. It is a close analogue of the Malay sponge cake, due to similar spongy holes, but the moisture and texture are slightly different.
