Mix the graham cracker crumbs with sugar and melted butter until the crumbs are evenly coated and resemble wet sand. Press this mixture firmly into the bottom of a greased 9-inch springform pan to form an even crust. Bake in a preheated oven at 175°C (350°F) for 10 minutes until fragrant. Let cool on a rack.
Combine the sliced strawberries with sugar and a squeeze of lemon juice in a bowl. Toss gently and let sit for 15 minutes until the berries release their juices and soften slightly, creating a flavorful syrup.
In a large mixing bowl, beat the softened cream cheese with an electric mixer until smooth and creamy. Add the sugar and vanilla extract, and continue beating until well combined and fluffy.
Pour in the lemon juice and mix briefly to brighten the flavor. Dissolve the gelatin in a small amount of warm water, then gently fold it into the cream cheese mixture, ensuring it’s evenly incorporated.
In a separate bowl, whip the heavy cream with an electric mixer until soft peaks form. Gently fold the whipped cream into the cream cheese mixture in batches, maintaining a light and airy texture.
Pour half of the cheesecake batter over the cooled crust and spread evenly. Spoon a layer of the macerated strawberries on top, pressing them lightly into the batter. Add the remaining batter on top, smoothing the surface with a spatula.
Bake the assembled cake in the oven for 45-50 minutes, until the edges are set and slightly golden, but the center still has a gentle jiggle. Cover with foil if the top starts to brown too quickly.
Remove the cake from the oven and cool it in the pan on a wire rack for one hour. Then, refrigerate uncovered for at least 4 hours or overnight to allow it to set completely and develop flavor.
Before serving, arrange the remaining sliced strawberries or whole berries on top for a vibrant finish. Chill for another 15 minutes if desired, then slice with a warm knife for clean cuts.
Slice the cake, serve chilled, and enjoy the luscious layers of creamy cheesecake complemented by juicy, bright strawberries.
