Firstly, you need to preheat the oven to 160°C.
Then melt the butter in a 28cm ovenproof frying pan over low heat. Next, blitz the biscuits until they are in a fine crumb, you can do this in a food processor.
Make sure to turn the heat off tip the biscuit crumbs into the pan and mix them well. Spread and pat out the mixture into an even layer, you can go up slightly onto the sides.
Bake this for five minutes and then remove it from the oven.
Crack the eggs into the processor with the vanilla and most of the icing sugar. Blitz this for two minutes, until it goes to a pale colour.
Then add in the cream cheese and lemon juice by blitzing them all together. Pour the mixture evenly over the biscuit base.
