01 - Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper, leaving overhang for easy removal.
02 - Combine flour, powdered sugar, and salt in a mixing bowl. Add cold butter and blend with a pastry cutter or fingertips until mixture resembles coarse crumbs.
03 - Press mixture evenly into the bottom of the prepared pan. Bake for 12–15 minutes until lightly golden.
04 - Puree the diced mango in a blender or food processor until smooth.
05 - Whisk eggs and sugar until slightly pale. Stir in flour, shredded coconut, coconut milk, lime juice, vanilla, baking powder, salt, and mango puree until fully combined.
06 - Pour the filling over the pre-baked crust. Sprinkle the remaining shredded coconut evenly on top.
07 - Bake for 18–22 minutes until edges are golden and center is set but slightly jiggly.
08 - Let cool completely in the pan on a wire rack. Lift out using parchment overhang and cut into bars.
