This lemon cheesecake was the favorite dessert at a charity buffet – it went like lightening. Once you’ve collected the ingredients together, it takes 10 minutes to make.

Mix the cookies with the butter in a bowl.
Line your round pan with parchment paper.
Press into the base of the pan(but not up the sides)
Put the mascarpone, lemon curd, and lemon juice in a bowl and beat with a spatula until smooth
Spoon on to the cookie base and level the top.
Chill in the fridge for at least 4 hours and up to 24 hours to firm up
To serve, remove the cheesecake from the pan, peel off the baking parchment.
Arrange on a platter.
Decorate with the fruit and dust with icing sugar.
