I never knew it's Malaysian, its called Mua Chee. In Chinese we call it Loh mai chi (糯米籽). My mom made it today ^^ it actually looks like a snowball with peanut filling. I really like it ~nom~nom~ This chewy sweet snack shaped as a snow ball can be compared with Tangyuan (湯圓). The dough is mainly maid with glutinous rice flour and the filling can vary. My favorite filling is the peanut sugar mix, but people will also make it with sweet red bean filling.
