Preheat your oven to 350°F (175°C). In a mixing bowl, combine graham cracker crumbs, melted unsalted butter, and granulated sugar until evenly mixed. Press this mixture firmly into the bottom of a greased 9-inch springform pan, creating an even layer. Bake for 8-10 minutes, or until golden brown, then let it cool completely while you make the filling.

In a large bowl, beat softened cream cheese with an electric mixer on medium speed until smooth and creamy. Gradually add granulated sugar and vanilla extract, mixing until well incorporated. Add each large egg one at a time, making sure to blend well after each addition. Finally, mix in the fresh mango puree and cornstarch until the filling is silky and lump-free.

Pour the creamy cheesecake filling into the cooled crust, spreading it gently to create an even surface. Prepare a water bath by placing the springform pan in a larger baking dish filled with hot water, which helps prevent cracks during baking. Bake for 50-60 minutes, checking for edges that are set and a slightly jiggly center. Turn off the oven and allow the cheesecake to cool gradually for 1 hour to stabilize its texture.

In a small saucepan, combine fresh mango puree, sugar, and lemon juice, heating over medium heat until the sugar dissolves and the mixture is well combined. Whisk together a small amount of cornstarch with water to create a slurry, then add it to the saucepan. Stir for 2-3 minutes until the mixture thickens, then remove from heat and let it cool to room temperature.

Once the cheesecake has cooled completely, pour the glossy mango glaze evenly over the top, ensuring it covers the surface beautifully. Place the assembled Tropical Mango Cheesecake in the refrigerator for at least 6 hours or overnight to allow it to set and allow the flavors to meld together perfectly.

When ready to serve your Tropical Mango Cheesecake, remove it from the springform pan and garnish as desired with fresh mango slices, a dollop of whipped cream, or sprigs of mint. Slice into generous portions, and savor the taste of this tropical delight with friends and family!
