Make the crust. Stir graham crumbs, melted butter, and a pinch of salt until the texture feels like wet sand and clumps when pressed.
Portion the crust. Spoon 1–2 tablespoons into each cup. Press down firmly with the back of a spoon to create an even base.
Beat the cream cheese. In a bowl, beat softened cream cheese with sugar until smooth and no lumps remain.
Add vanilla and lemon juice; mix again.
Fold in Cool Whip. Gently fold the Cool Whip into the cream cheese mixture until fully combined and airy. Do not overmix.
Fill the cups. Spoon or pipe the cheesecake filling over the crusts, leaving a little room on top for garnish.
Chill. Cover and refrigerate for at least 1–2 hours, or until set and nicely chilled. Overnight is great for deeper flavor.
Top and serve. Add berries, pie filling, or your favorite topping right before serving.
