Whisk together the caster sugar, brown sugar and egg until light and pale.
Melt together the dark chocolate and butter, and pour it into the egg and sugar mixture.
Fold in the flour and cocoa powder and transfer it into the base of the loaf pan.
Whisk all the cheesecake ingredients together in a bowl, until everything is smooth and well combined (I added the melted chocolate at the end).
Pour the mixture over the brownie batter and bake at 200° for 25/30mins or until the cheesecake is dark brown from the top and still slightly jiggly in the middle.
Cool, slice and enjoy ☺️!!
