How to Make No Bake Mango Cheesecake

Step 1 - Make the crust: Combine the crushed biscuits and melted butter until the crumbs are evenly moistened and resemble wet sand. Press the mixture firmly into the base of a lined springform pan, using the bottom of a glass or measuring cup to compact it into a smooth, even layer. Chill the crust for at least 20 minutes so it firms up before the filling goes in.

Step 2 - Whip the cream: Pour the cold heavy cream into a chilled bowl and whip it until medium-stiff peaks form. The cream should hold its shape but still look smooth and soft rather than overbeaten. Set it aside in the refrigerator while you prepare the cream cheese base.

Step 3 - Make the cheesecake filling: Beat the softened cream cheese with the powdered sugar, vanilla, and lemon juice until completely smooth and fluffy. There should be no visible lumps at all before you move on. Fold the whipped cream gently into the cream cheese mixture in batches so the filling stays light and airy. Spoon the filling over the chilled crust and smooth the top carefully with an offset spatula or the back of a spoon.

Step 4 - Prepare the mango topping: Blend the mango flesh into a smooth puree. If the puree is already thick, glossy, and spoonable, you can use it as is. If it is thin or watery, transfer it to a small saucepan and heat it gently with the cornstarch slurry, stirring constantly until it thickens slightly. Let it cool completely before spreading it over the cheesecake layer, because warm topping can soften the filling underneath and disturb the clean layers.

Step 5 - Chill and serve: Pour the cooled mango topping over the cheesecake and spread it into an even layer. Cover the pan and chill for at least 6 hours, though overnight is better for the cleanest slice. Unmold carefully, garnish if desired, and cut with a sharp knife wiped clean between slices so the mango layer stays glossy and neat.
