Put the biscuits in a ziplock and crush them finely. Put them in a bowl, add melted butter and 2 tablespoons sugar.
Grease the bottom and sides of a springform pan with butter and add the crust. Place the springform in the fridge.
For the green cheesecake filling, mix cream cheese with yoghurt and mascarpone in a bowl. Add matcha powder.
Soak the gelatine leaves in cold water for at least 5 minutes. Remove the sheets from the water and squeeze out the excess liquid. Melt them in a saucepan and directly add them into the cream cheese mixture.
Pour the mixture onto the pie crust and put it back in the fridge.
For the white cheesecake filling, mix cream cheese, yoghurt and mascarpone. Season with grated lime zest and lime juice. Prepare the gelatine and stir it into the cheese mixture. Pour the filling on top of the green cream cheese filling and refrigerate it for at least 4 hours.
Notes
Dust the cheesecake with matcha powder just prior to serving.
