Preheat the oven to 160℃. Line a 18cm springform cake tin with baking paper and cover the bottom with foil.
For the base, mix crumbled Biscuits and melted Butter until moist. Place into the cake tin and press firmly over the base.
Process all ingredients until smooth. If you don’t have food processor, mix all ingredients very well using electric beater or hand mixer.
Pour into the cake tin over the base but save small amount. Add some Matcha powder to the saved mixture and make it darker green. Using this mixture you can create decoration but it is optional.
Place the tin in a roasting pan, pour boiling water to the pan about 2cm deep. Bake for 50 minutes or until just set. Allow to cool completely.
*Note: This steam baking method is optional. You can bake this cake without hot water for drier result.
