03 - 1/4 cup sweetened shredded coconut
04 - 1/4 cup granulated sugar
05 - 1/4 teaspoon salt

13 - 1/2 cup whipped cream
14 - 2 tablespoons toasted shredded coconut

# How-To Steps:

01 - Preheat oven to 350°F. Line an 8-inch square baking pan with parchment paper, leaving a 2-inch overhang for easy removal.
02 - In a mixing bowl, combine graham cracker crumbs, melted butter, sweetened shredded coconut, granulated sugar, and salt. Mix thoroughly until the texture resembles damp sand.
03 - Press the graham mixture evenly into the bottom of the prepared pan. Bake for 10 minutes. Remove and allow to cool slightly.
04 - In a separate bowl, whisk together sweetened condensed milk, egg yolks, lime juice, lime zest, coconut cream, flour, and vanilla extract until fully blended and smooth.
05 - Pour the coconut lime mixture over the cooled crust. Smooth the top with a spatula for even coverage.
06 - Bake for 18 to 20 minutes, until the edges are set and the center is slightly wobbly. Avoid overbaking.
07 - Cool in the pan at room temperature for 1 hour, then refrigerate for at least 2 hours until thoroughly chilled.
08 - Lift out using the parchment paper overhang and cut into 16 bars.
09 - Top each bar with whipped cream, toasted shredded coconut, and additional lime zest if desired. Serve well chilled.
