01 - Preheat oven to 350°F. Line two baking sheets with parchment paper for easy cleanup and to prevent sticking.
02 - In a medium bowl, whisk together all-purpose flour, baking soda, and salt until thoroughly incorporated.
03 - In a large mixing bowl, combine granulated sugar, powdered sugar, melted coconut oil, coconut milk, and vanilla extract. Whisk until mixture is smooth and creamy.
04 - Add the dry ingredients to the wet mixture. Stir with a spatula or wooden spoon until just combined, being careful not to overmix.
05 - Fold in shredded coconut and chopped hibiscus flowers until evenly distributed throughout the dough.
06 - Scoop tablespoon-sized portions of dough and roll into balls. Place on prepared baking sheets, spacing 2 inches apart to allow for spreading.
07 - Gently flatten each ball with your palm or the bottom of a glass. Optionally, dust tops with powdered sugar for a decorative finish.
08 - Bake for 10 to 12 minutes, or until edges are lightly golden and centers are set.
09 - Let cookies cool on the baking sheet for 5 minutes to set, then transfer to a wire rack to cool completely before serving.
