For Coating : Add 30g glutinous rice flour in a pan (do not add oil), cook it under low heat for few minutes. Keep stirring and set aside.

Mix 150g glutinous rice flour, rice flour and sugar together. Add in water and mix well until smooth. Add in banana flavouring, mix well. 

Lightly brush the plate with oil, then pour the batter into a plate. Steam under high heat for 20 minutes. 

Sprinkle some cooked glutinous rice flour on a table, place the dough on top and coat with more glutinous rice flour. Place a parchment paper on top and roll it. 

Then roll it into long roll and cut into small pieces.
