Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking pan.
In a large bowl, combine chocolate cake mix, water, vegetable oil, and eggs. Mix until smooth.
Pour the batter into the prepared baking pan and bake for 30 minutes.
Remove from the oven and let it cool for 10 minutes.
Poke holes in the cake with a fork, about 1 inch apart.
In a separate bowl, mix sweetened condensed milk and chocolate syrup.
Pour this mixture evenly over the cake, allowing it to soak into the holes.
Cool the cake completely before topping with whipped topping, coconut, and pecans.
Drizzle chocolate frosting over the top for added richness.
