Preheat your oven to 350°F (175°C). This ensures that your cookies bake evenly and come out perfectly chewy.
Line your baking sheet with parchment paper. This will help your cookies release easily once baked.
In a mixing bowl, combine the flour (or protein powder), cocoa powder, shredded coconut, and salt. Whisk these together until they are well mixed.
In a separate bowl, mix together the milk, maple syrup (or honey/agave), and vanilla extract. Stir until fully combined.
Pour the wet mixture into the dry mixture. Stir until just combined. Be careful not to overmix; a few lumps are perfectly fine!
Using a cookie scoop or tablespoon, drop rounded balls of dough onto your prepared baking sheet. Leave some space between each cookie, as they will spread slightly while baking.
Place the baking sheet in the preheated oven and bake for 10-12 minutes. The edges should be set, while the centers will remain slightly soft.
Remove the cookies from the oven and allow them to cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely.
