This here is Ondeh ondeh (also spelled as "Onde onde"), a Malaysian snack.
So, what is Ondeh ondeh?
Basically, it's a glutinous rice ball, with melted gula melaka in the center, and grated coconut on the outside. When you bite into its chewy outer layer, the sweet gula melaka oozes out, and brings a delightful sensation to your mouth.
A word of warning when eating- make sure you pop the whole thing into your mouth, otherwise the gula melaka might squirt out at someone/something. ^^;
