Preheat oven to 395℉
Line an 8 or 9” springform pan with a removable base with parchment paper that comes all the way up the sides of the pan.
Beat the cream cheese and sugar in a large bowl, until smooth.
Add the eggs, greek yogurt, vanilla and flour and beat until smooth.
Fold in the orange zest.
Pour into the prepared pan and bake for 1 hour until the cake is browned on top, and not completely set in the centre.
Turn oven off and allow the cake to cool in the oven, with the door slightly open for 40-45 minutes.
Remove from oven and allow to cool before placing the the fridge to set completely, about 6 hours, but preferably overnight.
Remove the cake from the pan and peel the parchment paper away.
Serve at room temperature.
