Preheat Oven: Set your oven to 350°F (175°C) and grease a 9×13-inch baking dish.
Prepare Cake: Prepare the German chocolate cake mix according to the package instructions and bake it in the prepared dish.
Poke Holes: Once the cake is baked and has cooled slightly, use a wooden spoon handle to poke holes all over the surface of the cake.
Layer Toppings: Pour the sweetened condensed milk and caramel sauce over the poked cake, allowing it to soak in. Evenly sprinkle chocolate chips, shredded coconut, and chopped pecans on top.
Drizzle Frosting: Heat the chocolate frosting and caramel frosting until they are pourable, then drizzle both over the cake.
Rest: Allow the cake to sit for at least 30 minutes, so all the flavors meld together beautifully.
Serve: Slice and enjoy this decadent dessert!
