Preheat oven at 165 deg C. Line one 8 inch square tray with parchment paper all sides up.

Pour matcha powder in a bowl and slowly add whipping cream into it. Stir the matcha mixture till smooth to a paste and set aside for later use.

Melt butter and white chocolate in a double boiler or microwave, stir until mixture smooth and combined.

Add beaten eggs into chocolate mixture, mix well followed by sugar and stir well again. Add bread flour into it and stir till mixture becomes batter.

Lastly add in the matcha paste and stir batter till smooth.

Pour matcha batter into prepared pan. Shake the pan slightly and smooth the top.

Pour water into a larger cake pan (9 or 10 inch pan) and place a wire rack in it. Then place the pan with matcha batter on top. Bake the brownie in the preheated oven for 40-45 minutes or until set.

Leave the cake to cool in pan, cover with aluminium foil and place it in refrigerator overnight. Then cut into small pieces and dust with some matcha powder on top just before serving.
