Preheat your oven to 325°F (165°C). Line a baking sheet with parchment paper or a silicone mat to prevent sticking.
In a large mixing bowl, use a whisk to beat the egg whites until they are frothy.
Add the granulated sugar, pure vanilla extract, and table salt to the frothy egg whites. Mix until well combined and the sugar dissolves.
Gently fold in the sweetened coconut flakes and all-purpose flour. Be careful not to overmix.
Using a cookie scoop or spoon, portion out the mixture onto the prepared baking sheet, leaving space between each mound.
Press a Hershey's Kiss into the center of each mound, ensuring it is secure but not completely submerged.
Bake for 15-20 minutes, or until the edges are golden brown. The centers may still be soft.
Allow the Coconut Blossoms to cool on the baking sheet for a few minutes, then transfer to a wire rack to cool completely. Enjoy warm or at room temperature!
