Preheat oven to 350? and line an 8x8 baking pan with foil and grease s bit with butter or non stick spray

Mix together the melted butter and crumbs until all the crumbs are moist and pack it evenly to the bottom of the pan

In a mixer gently beat the cream cheese until smooth and add in the sugar and beat until just incorporated

Gradually add in the yogurt, egg whites, vanilla and flour (making sure not to over beat)

Mix in lemon juice

Pour batter all over crumbs and spread evenly

Take jam and microwave for about 10- 15 seconds and stir until smooth

Drop dollops all over th top of the cheesecake and with a toothpick run it through the jam and the cheesecake mix to create the marble effect! Use as much or as little of the jam until you're happy with the look!

Bake for 20-30 minutes or until the sides pull away from the pan and the centre is still a bit not set. If it starts to crack you're over baking it!

Allow to cool at room temp for an hour or so before putting it in the fridge for several hours until completely set.

Overnight is best!
