Klepon (Javanese: ꦏ꧀ꦭꦼꦥꦺꦴꦤ꧀, romanized: klêpon) or kelepon or kalalapun, also known outside Java as onde-onde[2] and buah melaka, is a sweet rice cake ball filled with molten palm sugar and coated in grated coconut.

[3][7] Klepon is a boiled rice cake filled with liquid palm sugar (gula jawa/merah/melaka) and coated in flaked coconut.

[4] The small pieces of palm sugar are initially solid when inserted into the glutinous rice dough and rolled into balls.

[8] Klepon are ideally left to cool for some time before consumption to prevent burning from the hot liquid palm sugar.

[11] In Java, onde-onde refers to the Chinese jian dui, a rice cake ball coated with sesame seeds and filled with sweet green bean paste.

[12] The ingredients for klepon, i.e. coconut, palm sugar, and glutinous rice flour are commonly familiar in traditional Indonesian kue making since ancient times, especially in Java.

[14] In the 1950s, klepon was introduced to the Netherlands by Indo immigrants and is readily available throughout the country in toko shops, Dutch or Chinese Indonesian restaurants, and supermarkets.
