Lunchbox Muffins

Preheat oven to 180oC (160oC fan). Generously grease a 20cm round, loose-bottom (or springform) tin. Line the base with baking paper.
In the bowl of a food processor, add biscuits. Blitz to a fine crumb. Add 250g of the melted butter and blitz until just combined. Spoon the mixture into the prepared tin and use a spatula to gentle push half of the mixture up the sides of the tin. Spread remaining mixture evenly over the base (using a drinking glass can help to compact the mixture around the sides and base). Refrigerate.

In the bowl of a stand mixer fitted with a whisk attachment, combine remaining butter with sugar and whisk until combined. With the motor running, add eggs one at a time until incorporated. Scrape down the sides of the bowl and add cream cheese, quark, sour cream and vanilla, whisk until smooth. Add cornflour and mix until incorporated.

Add peel and sultanas and gently fold through the cream mixture, then spoon into the prepared base and smooth the surface.
Bake cheesecake for 10mins then reduce oven temperature to 170°C (150°C fan) and bake for a further 50 mins. Turn off the oven, leaving the door slightly open, allow cheesecake to sit in the oven for a further hour until the edges of the cheesecake feel firm when gently pressed.

Allow the cheesecake to cool completely at room temperature then remove sides of tin and transfer cheesecake to refrigerator to cool overnight.
To make the meringue decoration, place the egg whites and caster sugar in a large bowl and whip into soft peaks. Spoon the meringue on top of the cheese cake and shape with a spatula. Use kitchen blow torch to lightly crisp the outside of the meringue. Serve and enjoy!
