Mochi dough : Mix the glutinous rice flour, milk, corn starch and sugar together in non-metal bowl (microwaveable bowl) until all ingredients are well mixed
Half cover the bowl with a cling film, and heat it up at 800W for 2 min in the microwave oven
Spoon the mochi out from the bowl with a metal spoon (to prevent sticking). Wrap it in a cling film, let it set aside
Cookie : Heat butter on a pan in low heat until it turns light brown, stir occasionally. Then leave it to cool in room temperature for 5 mins
Gently blend the dark brown sugar and white sugar into the melted butter
Beat the egg and blend it to the butter mixture, then add salt and baking powder, stir to mix
Add the sifted flour and matcha powder into the mixture, mix it gently until it is fully incorporated
Preheat the oven at 180 degree Celsius
