Prepare the Crust
In a bowl, combine graham cracker crumbs, melted butter, and sugar. Stir until well mixed.
Spoon about 2 tbsp of the crumb mixture into the bottom of each serving cup or jar. Press down firmly to form an even crust layer. Chill in the fridge while making the filling.
Make the Cheesecake Filling
In a large mixing bowl, beat softened cream cheese until smooth using an electric mixer.
Gradually add powdered sugar, vanilla extract, and lemon juice (if using), and beat until combined and smooth.
In a separate bowl, whip the heavy cream until stiff peaks form (about 2–3 minutes).
Gently fold the whipped cream into the cream cheese mixture until fully incorporated.
Assemble the Cheesecake Cups
Spoon the cheesecake filling into the cups over the chilled crust layer, dividing it evenly among the cups.
Smooth the top with a spoon or spatula.
Chill
Refrigerate the cheesecake cups for 2–4 hours, or until set.
Add Toppings
Just before serving, add fresh berries, caramel sauce, chocolate drizzle, or any topping of your choice.
