Creating Raspberry Mango Bars is simple if you follow these easy steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease an 8-inch square baking dish or line it with parchment paper for easy removal.
2. Prepare the Crust: In a mixing bowl, combine the flour, granulated sugar, and salt. Stir in the melted butter until the mixture resembles wet sand. Press this mixture into the bottom of the prepared baking dish to form an even crust.
3. Bake the Crust: Place the crust in the preheated oven and bake for 15-18 minutes or until lightly golden. Remove from the oven and let it cool slightly.
4. Prepare the Filling: In another bowl, whisk together the eggs, vanilla extract, cornstarch, and lemon juice until well combined. Gently fold in the raspberries and mango.
5. Pour the Filling: Spread the fruit mixture evenly over the cooled crust, ensuring it covers the surface well.
6. Bake Again: Return the dish to the oven and bake for an additional 25-30 minutes or until the filling is set and slightly golden around the edges.
7. Cool Completely: Remove from the oven and allow the bars to cool in the baking dish for about 1 hour. Once cooled, refrigerate for at least another hour to firm up before cutting.
8. Slice and Serve: Once chilled, slice the bars into squares. Dust with powdered sugar before serving for an elegant touch.
