Crush biscuits into fine crumbs and mix with melted butter. Press the mixture into the bottom of a springform pan to create a firm, even crust. Chill in the fridge while preparing the filling.

Beat cream cheese and powdered sugar until smooth. Add vanilla or lemon juice and mix well. Whip cold heavy cream to stiff peaks in a separate bowl, then gently fold it into the cream cheese mixture.

Pour the filling over the chilled crust and smooth the top. Cover with plastic wrap and refrigerate for at least 4 hours, or overnight.

Remove from the pan, slice, and top with fresh berries or fruit sauce for added flavor. Enjoy!
