In a mixing bowl, combine graham cracker crumbs and melted butter until the mixture resembles wet sand. Spoon this mixture evenly into the bottom of your dessert cups, pressing down firmly to create a solid crust. Refrigerate for about 30 minutes.

In a chilled bowl, whip heavy cream until soft peaks form, about 3-4 minutes. In another bowl, blend room-temperature cream cheese with powdered sugar and chosen flavor add-ins until smooth. Gently fold the whipped cream into the cream cheese mixture until fully combined.

Begin layering by adding a spoonful of filling over the chilled crust in each cup. Follow with another layer of crust, then repeat the filling process until cups are nearly full. The final layer should be creamy filling.

Cover the cups with plastic wrap or foil, and refrigerate for at least 2 hours to allow flavors to meld and filling to firm up.

Just before serving, add desired toppings such as fresh fruits or a drizzle of chocolate sauce. Keep wet toppings minimal until serving to prevent sogginess.
