Follow these simple steps to create your Mango Cheesecake Bars:

1. Prepare the Crust: Preheat your oven to 350°F (175°C). In a bowl, combine graham cracker crumbs, melted butter, and sugar. Mix until well combined.
2. Press the Crust: Press the mixture evenly into the bottom of a greased 9×9-inch baking pan. Bake for 10 minutes, then remove from the oven and let cool.
3. Make the Cheesecake Filling: In a mixing bowl, beat the softened cream cheese and sugar until smooth. Add the vanilla extract and mix well.
4. Add Eggs and Sour Cream: Add the eggs one at a time, mixing well after each addition. Finally, stir in the sour cream until fully combined.
5. Pour Filling: Pour the cheesecake filling over the cooled crust, spreading it evenly.
6. Bake: Return to the oven and bake for 25-30 minutes, or until the edges are set and the center is slightly jiggly.
7. Cool the Cheesecake: Turn off the oven and crack the door, allowing the cheesecake to cool gradually for about 30 minutes.
8. Chill: Place the cooled cheesecake in the refrigerator to chill for at least 1 hour, or until completely set.
9. Prepare the Mango Topping: In a bowl, combine diced mangoes, honey, and lemon juice. Toss until the mango is well coated.
10. Top the Cheesecake: Once the cheesecake is fully chilled, spread the mango topping evenly over the top.
11. Slice: Cut into squares and serve chilled.
