Preheat your oven to 325°F (163°C). Line a baking sheet with parchment paper to prepare for baking.
In a medium bowl, combine the sweetened flake coconut, sweetened condensed milk, vanilla extract, and kosher salt. Stir until everything is well combined.
In a separate large bowl, use an electric mixer to beat the egg whites until they form stiff peaks. This will take about 2-3 minutes. Be careful not to overbeat.
Gently fold the coconut mixture into the whipped egg whites. Use a spatula to combine the two mixtures without deflating the egg whites too much.
Using a scoop or spoon, portion the mixture onto the prepared baking sheet, spacing them about 1 inch apart. You can shape them into mounds if you prefer a more rustic look.
Bake in the preheated oven for 20-25 minutes or until the tops are golden brown. Keep an eye on them to ensure they don’t burn.
Remove from the oven and let the macaroons cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely. Enjoy them as is, or dip them in melted chocolate for an extra treat!
