Place the graham crackers in a food processor or zip-top bag and crush them until fine crumbs form. Pour the crumbs into a mixing bowl and stir in the melted butter until evenly coated. Press this mixture firmly into the bottom of a springform pan, using the back of a spoon or a glass to smooth and compact it. Chill in the fridge for about 15 minutes to set.
In a large bowl, beat the softened cream cheese with a hand mixer or a sturdy spatula until smooth and fluffy, about 2-3 minutes. Add the sifted powdered sugar and mix again until fully incorporated, creating a creamy, slightly tangy base.
In a separate bowl, whip the heavy cream until soft peaks form, just until it holds gentle swirls when you lift the beaters. Carefully fold the whipped cream into the cream cheese mixture using a spatula, mixing gently until well combined and light in texture. Add the lemon juice and fold again to brighten the filling.
Hull and mash the strawberries with a fork or potato masher until chunky but smooth. Gently swirl the mashed strawberries into the cream cheese filling, creating a marbled effect with streaks of bright red throughout.
Pour the strawberry cheesecake filling over the chilled crust, spreading it evenly with a spatula. Smooth the top and garnish with whole or halved strawberries if desired. Cover loosely with plastic wrap and refrigerate for at least 4 hours or overnight to allow the cheesecake to set properly.
Before serving, run a warm knife along the edges of the cheesecake to ensure clean slices. Carefully remove the sides of the springform pan and transfer the cheesecake to a serving plate. Slice with a sharp knife and enjoy this fresh, creamy dessert that captures summer’s bright flavors.
