Preheat your oven according to the cake mix directions. Grease and flour a 9x13 inch pan. In a large bowl, combine the cake mix, water, vegetable oil, and eggs. Mix until smooth, pour the batter into your prepared pan, and bake according to package directions until a toothpick inserted into the center comes out clean.

Once the cake is cool, take a wooden spoon handle or something similar and poke holes all over the surface of the cake, ensuring enough holes for the sweet goodness to seep in.

In a separate bowl, combine the sweetened condensed milk and chocolate syrup until well blended. Pour this mixture over the poked cake, letting it seep into the holes.

In a saucepan, combine the evaporated milk, sugar, butter, and egg yolks over medium heat. Stir continuously until the mixture starts to thicken, about 10 minutes. Remove from heat and add the vanilla, coconut, and pecans. Let it cool slightly before spreading it over the cake.

Allow your cake to chill in the fridge for at least an hour before serving so the flavors meld beautifully.
