Start by peeling and slicing ripe mangoes, then blend them in a food processor or blender until very smooth. Aim for about 1 ½ cups of mango puree, which will be the star of your No Bake Mango Cheesecake. Set aside ¼ cup of the puree for topping later, and ensure the rest is ready for the filling.

In a mixing bowl, combine graham cracker crumbs, light brown sugar, melted unsalted butter, and a pinch of kosher salt. Stir until the mixture resembles wet sand. Firmly press this mixture into the bottom of a springform pan, creating an even layer. Place it in the freezer for about 10-15 minutes to help the crust set while you prepare the filling.

Using an electric mixer, beat the full-fat cream cheese in a large bowl until it is smooth and creamy. Gradually add in sweetened condensed milk, vanilla extract, and fresh lime juice, mixing well until everything is well combined.

In a small bowl, sprinkle the gelatin over cold water and let it sit for about 5 minutes until it thickens. Then, gently heat this mixture in the microwave for about 15 seconds or on the stove until melted, ensuring it doesn't boil. Combine the melted gelatin with the remaining mango puree, stirring until fully integrated.

Gently fold the mango puree and gelatin mixture into the cream cheese mixture, incorporating it carefully to maintain the light and fluffy texture.

In a separate bowl, use a whisk or electric mixer to whip the heavy cream and powdered sugar together until stiff peaks form. Once whipped, gently fold the whipped cream into the mango cheesecake batter until it’s smooth and evenly blended.

Take the crust out of the freezer and pour the creamy cheesecake filling into it. Smooth the top with a spatula, ensuring an even surface. Swirl the reserved mango puree on top for a beautiful marbled effect.

Cover the cheesecake with plastic wrap or a lid and refrigerate for at least 8 hours, or overnight if possible.
