Add the vanilla and eggs and mix for another minute. Now add the flour, cocoa powder and salt and mix again on low speed. Add the chopped chocolate and stir through with a spatula. Pour the batter into the prepared baking tin and bake for 45 minutes. Remove from the oven and cool in the baking tin.

For the biscuit base: Preheat your oven to 180℃ and line a 12-hole muffin tin with paper cups. Spray the paper cups with baking spray and set aside. Process the biscuits to crumbs. Whisk the egg white with a fork until just frothy and add to the crumbs. Add the melted butter and give everything a good mix. The mixture should resemble wet sand. Divide between the cupcake liners and press the mixture down firmly into the bottom of each cup. Bake in the oven for 5 minutes. Remove and allow to cool.
For the filling: Turn you oven temperature down to 160℃. Chop the chocolate into small pieces and place it in a heatproof bowl set over a saucepan with simmering water. Allow to melt completely, remove from the heat and set aside to cool. Add the cream cheese, sugar and cocoa powder to the bowl of a stand mixer fitted with the paddle attachment. Beat on low speed until combined, scraping down once or twice between mixing. Remove the mixing bowl from the mixer, add the melted chocolate and fold in until no streaks remain. Divide the batter evenly between the cupcake cups. Bake for 15 minutes or until just set in the centre. Turn off the oven and leave the cheesecakes inside with the door closed, for 30 minutes. Remove from the oven and cool completely in the baking tin. Refrigerate the cheesecakes for 1 hour before adding the topping.
Marshmallow-Meringue Topping: Turn your oven to the grill setting and move the oven rack to the top position. If you are going to blow-torch your toppings you may leave your oven off. Add the egg whites and sugar to a heatproof bowl and place the bowl over a saucepan with simmering water. Whisk the mixture for about 3 minutes until the sugar has dissolved and the mixture is very frothy. Remove from the heat and pour the mixture into the bowl of a stand mixer fitted with the whisk attachment. Add the vanilla and cream of tartar. Beat on high speed for about 6 minutes, until very thick and glossy. Spoon or pipe the topping on the cheesecakes and either place under the grill to toast or blow-torch the topping.
