To Prep
Preheat oven to 200°C fan forced.
Grease 2 ramekins with butter and dust with matcha powder so that it is easier to remove the cake when it is baked.
Combine matcha powder and hot water and mix well until it becomes a paste. Set aside.
To Make Lava Cake
Boil some water in a saucepan. Place white chocolate and butter into a large bowl and place over the boiling water. Stir until chocolate and butter are melted and well mixed. Remove from double boiler and let cool slightly.
Add egg into the mixture and whisk to combine well.
Add matcha paste and whisk to combine well, use a spatula or spoon to help with breaking the clumps.
Add flour and mix until well combined.
Divide the batter into 2 portions and pour into the ramekins.
Bake for 7-8 mins, or until the top of the cake forms into a crust and not moist. Make sure they are not overbaked.
Remove from the oven and invert onto plates.
Optional: Add red bean paste and white chocolate chips to the side, dust with icing sugar and matcha powder.
Serve immediately.
Tip
Only dust a little matcha powder to serve, or else it might get too bitter.
