In the food processor, add the biscuits and blitz until crumbs; add the melted butter and blitz again until combined, and the mixture looks like wet sand.
Press the mixture into the bottom of a 22cm springform until it is an even layer. Refrigerate it until the filling is made.
Add the heavy cream to a mixing bowl and whisk with an electric whisk until a soft peak forms.
In another bowl, mix cream cheese, sugar, and vanilla extract until creamy and smooth.
Now, fold the whipped cream into the cream cheese mixture until smooth, and stir in the raspberries (keep a few to decorate with).
Scoop the filling onto the biscuit crumbs base and refrigerate for 4-6 hours or overnight.
Top it with the remaining raspberries and sprinkle with powdered sugar. Cut the cheesecake and serve.
Notes
I like to chill my cheesecake overnight! It makes cutting easier and cleaner.
