Grease a pan with little butter and put a parchment paper. Crush the biscuits on a food processor and place it in a bowl. Melt the butter and add it on the biscuits. Mix well and put it n the pan. Press with a spoon to make an even surface.

Preheat the oven to 180 degrees.

Beat the cream cheese with the sugar, the orange zest and the vanilla. Add one by one the eggs and mix slightly. Place it on the top of the base. Bake for around 1 hour. Switch of the oven and open the oven door little bit and leave the cheesecake inside the oven for around 1 ½ hour.

Run a knife around the pan rim and remove it. Then slide the parchment paper out from underneath.

Refrigerate the cheesecake for 4 hours. Decorate it as you wish. I use blueberry jam and flowers. Enjoy!
