Preheat oven to 200°C fan-forced. Line a 22cm spring form tin with two pieces of baking paper.
To do this, tear off two lengths of baking paper bigger then the tins. Place one sheet over the tin, then place the second sheet across the first. Press paper down firmly to cover the base and sides of the tin, then fold the overhanging paper – slightly over the rim.
The paper creases will add character to the cooked cheesecake, while the excess paper on top will prevent the cake from overcooking.
Beat the cream cheese in a stand mixer with a a paddle attachment on medium speed until smooth. Gradually beat in the cream until just combined scraping down the sides of the bowl. Add caster sugar and salt; beat for 2 minutes. Add plain flour, cornflour and 2 egg yolks; beat until incorporated. Add whole eggs, one at a time, beating after each addition, until just combined (3 minutes).
Sieve the mixture into prepared tin and level. Bake on the middle shelf of the oven until top is deeply caramelised (40minutes). Reduce temperature to 150°C and bake until cheesecake is cooked but has a slight wobble in the centre (15 minutes). Cool completely before taking out of the tin.
To serve, ease the baking paper away from the sides of the cheesecake and cut with a hot dry knife, wiping between cuts.
