Instructions
Make Coconut-Pecan Filling First
In a 3 quart saucepan off heat, whisk together egg yolks, evaporated milk and both sugars. Cut the butter into thin slices and add to the mixture. Set over medium heat and cook the mixture at a low boil/rapid simmer, stirring constantly, until the mixture thickens slightly, starts to smell good and darkens to a butterscotch color. This should take from 5 to 10 minutes. If any lumps form, pour it through a strainer. Let it cool, then stir in the vanilla, salt, coconut and pecans.
Cakes
Preheat oven to 350 degrees. Line 20 to 24 cupcake cups with paper liners.
Thoroughly whisk or stir together the flour, cocoa powder, baking soda, and salt, whisking out any lumps.
With an electric mixer on medium-high speed, cream butter and sugar until pale and fluffy. Add eggs, one at a time, beating until each is incorporated, scraping down sides of bowl as needed. Beat in vanilla. Reduce speed to low. Add flour mixture and buttermilk alternately, stirring until blended. Lastly, stir in the cooled melted chocolate.
Divide batter evenly among prepared cups, filling each about ¾ full. Do not overfill, as they will rise quite a bit. Bake for 20 to 22 minutes, then transfer to wire racks to cool. After about 10 minutes, remove from cupcake tins.
To assemble cupcakes, scoop out a little cake from the center to make a small (about 1 inch wide and ½ deep) well. Add a spoonful of coconut-pecan mixture heaping it so it comes up in the middle.
Once all of the cupcakes are filled, make your chocolate icing and pipe it around the edge.
Whipped Chocolate Ganache
Put the chopped chocolate in a microwave-safe bowl.
Heat the cream in microwave-safe measuring cup or in a saucepan just until it starts to boil, then pour over the chocolate. Let stand for one minute, then stir until smooth. If it doesn't melt all the way, you can microwave the ganache for 30 seconds. Let it cool at room temperature for about 30 minutes. It will thicken slightly, but will still be runny. Put it in the refrigerator for about 30 minutes or until it is very cold.
Scrape into a mixing bowl and beat with a hand-held mixer until it is stiff enough to pipe. Transfer to a pastry bag and pipe it in a circle around the filled cupcakes.
