Prepare the Base – In a bowl, mix the crushed Lotus biscuits with melted butter and milk. Press into the bottom of a springform pan and refrigerate for 15–20 minutes.
Make the Filling – Beat the cream cheese and powdered sugar until smooth. Add lemon juice, lemon zest, and vanilla extract, mixing well.
Whip the Cream – In a separate bowl, whip the heavy cream until soft peaks form. Fold it gently into the cream cheese mixture. If using gelatin, mix it in at this stage.
Assemble & Chill – Pour the filling over the chilled base, smoothing the top. Cover and refrigerate for at least 4 hours or overnight for the best results.
Garnish & Serve – Before serving, top with whipped cream, lemon slices, and biscuit crumbs. Slice and enjoy!
