Preheat oven to 350 degrees F (180 C). Line a 12-cup muffin tin (standard size) with paper liners; set aside. Stir together coconut, chocolate and pecans; set aside.
Mix together flour, baking powder, and salt; set aside.
Cream butter and sugar in a large mixing bowl, using an electric mixer, until pale and fluffy. Add eggs and vanilla; mix until combined. Reduce speed to low or by hand, stir in flour mixture, scraping down sides of bowl, until well combined. Mix in about a cup of the coconut mixture.
Divide batter among muffin cups, filling each about three-quarters full. Sprinkle remaining coconut mixture over tops and bake on center rack for about 25 minutes or until a cake tester comes out with moist crumbs.
