Kaya (Nyonya Coconut and Egg Jam) refers to a coconut jam from Malaysia which is made from coconut milk, duck eggs or chicken eggs, flavored with pandan leaves and sweetened with sugar. It is widely eaten in Southeast Asia either as a spread on a piece of toast, bread or crackers. It is used as a topping for Nyonya Kuih or as fillings for Bao (steamed buns) and baked buns.
Kaya-filled steamed buns are called Kaya Bao.
A similar product exists also in the Philippines and it is called Matamis na Bao. The only difference is that no egg is added to Philippines version and it is not also flavored with anything.
