Preheat your oven to 170°C (325°F). In a food processor, blend the tennis biscuits until finely crushed. Combine the crushed biscuits with melted unsalted butter in a bowl, mixing until well combined. Press this mixture firmly into the bottom of a lined springform pan, creating an even layer. Bake the crust in the preheated oven for about 10 minutes, until lightly golden, and set aside to cool.

In a large mixing bowl, combine the softened cream cheese and castor sugar. Using an electric mixer, blend until the mixture is smooth and creamy, about 2 minutes. Gradually add the eggs, one at a time, mixing well after each addition. Stir in the vanilla extract and whipping cream until everything is thoroughly combined, creating a luscious, creamy filling for your guava cheesecake.

Pour the cheesecake mixture over the cooled crust, smoothing it out with a spatula. Prepare a water bath by placing the springform pan into a larger baking dish, then fill the outer dish with hot water until it reaches halfway up the sides of the pan. Bake in the oven for approximately 50 minutes, or until the cheesecake is set with a slight jiggle in the center, ensuring a creamy texture.

After baking, turn off the oven and let the cheesecake cool in the oven for 2 hours. This gradual cooling will help prevent cracks. Once cooled, carefully wrap the springform pan with plastic wrap and refrigerate the cheesecake overnight to set completely, allowing the flavors to meld beautifully.

While the cheesecake is chilling, prepare the guava compote. In a saucepan over medium heat, combine chopped fresh guavas, lime juice, and granulated sugar. Cook for about 15–20 minutes, stirring frequently, until the guavas have broken down and the mixture thickens. For a smoother texture, blend it and strain if desired, letting it cool to room temperature.

Once the cheesecake has fully set, carefully remove it from the springform pan. Top with the homemade guava compote, letting it cascade beautifully over the creamy surface. For a finishing touch, decorate with fresh guava slices on top, adding a vibrant contrast. Slice and serve this decadent guava cheesecake, delighting everyone with its tropical flavor!
