In a large bowl, using a hand or stand mixer fitted with the whisk attachment, beat the cream cheese on high speed until completely smooth, about 1 minute. On medium-high speed, whip the yoghurt until fully combined. Then beat in the eggs and egg yolks until just combined. Finally, stir in the sugar, lemon juice, lemon zest and vanilla paste until everything is combined and no lumps remain in the filling.Pour the filling over the crust. Bake for 34 to 38 minutes, or until the centre of the bars are no longer wobbly. Allow to cool at room temperature for 30 minutes, then transfer to the fridge to chill for a further 3 to 4 hours, or even overnight.

Once cooled, lift the foil out of the container with the overhang on the sides and cut into squares. For clean squares, use a very sharp knife, wiping with a paper towel after each cut.
