01 - Preheat oven to 350°F. Line an 8-inch square baking pan with parchment paper, leaving an overhang on the sides for easy removal.
02 - In a bowl, combine all-purpose flour, unsweetened shredded coconut, melted unsalted butter, granulated sugar, and salt. Mix until the ingredients are thoroughly incorporated.
03 - Firmly press the crust mixture into an even layer at the bottom of the prepared pan. Bake in the preheated oven for 12 to 15 minutes, until the crust is lightly golden. Remove and let cool slightly.
04 - In a separate bowl, whisk together granulated sugar, all-purpose flour, salt, lemon zest, and fresh lemon juice. Add eggs and coconut cream, whisking until the mixture is smooth and fully blended.
05 - Pour the lemon coconut filling evenly over the baked crust. Dollop mashed fresh raspberries on top and gently swirl with a toothpick or knife to create a marbled effect.
06 - Return the pan to the oven and bake for 20 to 22 minutes, or until the center is just set and lightly jiggly. Remove from oven and let cool to room temperature.
07 - Once cooled, refrigerate the bars for at least 1 hour to allow the filling to set completely. Use the parchment overhang to lift from the pan, then slice into squares.
08 - Dust the bars with powdered sugar and sprinkle with toasted shredded coconut, if desired, before serving.
