In a small sauce pan, combine water, butter, and sugar. Heat over medium heat, stirring frequently, until boiling. Remove from heat and stir in chocolate chips until melted.
Add eggs and vanilla, and stir well until smooth. Add flour, baking soda, and salt, and stir until smooth and shiny. Dough will be very sticky, like brownie batter.
Using your medium disher (or a tablespoon if you don’t have one), scoop up a spoonful of dough, and push a piece of Mounds into the center. This will cause the dough to ooze out of the top a little. Use your fingers to push that excess dough over the piece of Mounds, covering it completely.
Drop candy-filled dough balls about two inches apart onto a baking sheet lined with parchment paper or a silicone baking mat. Sprinkle each cookie with coconut, then bake for 18-20 minutes.
Cool on baking sheet for 5-10 minutes, then transfer to cooling rack to cool completely. Enjoy with a cold glass of milk!
