Equipment

  • 9×13-inch baking dish
  • Mixing bowls
  • Wooden spoon or fork (for poking holes)
  • Whisk (for ganache)
  • Microwave-safe bowl

Ingredients
  

  • For the Cake:
  • 1 box German chocolate cake mix plus ingredients listed on the box
  • 1 3.9 oz box instant chocolate pudding mix
  • 1 cup plain Greek yogurt or sour cream
  • For the Filling:
  • 1 14 oz can sweetened condensed milk
  • 1 cup semi-sweet chocolate chips
  • ½ cup heavy cream
  • For the Topping:
  • 1 tub coconut-pecan frosting store-bought or homemade
  • ½ cup chopped pecans optional
  • ½ cup toasted coconut flakes optional

Instructions
 

  • 1️⃣ Prepare the Cake
  • Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish.
  • Prepare the cake batter according to the package instructions, then stir in the chocolate pudding mix and Greek yogurt (or sour cream) for extra moisture.
  • Pour the batter into the prepared baking dish and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
  • 2️⃣ Poke & Fill the Cake
  • Let the cake cool for 10 minutes, then use the handle of a wooden spoon or fork to poke holes all over the cake.
  • Pour the sweetened condensed milk evenly over the cake, letting it soak into the holes.
  • 3️⃣ Make the Ganache
  • Heat the heavy cream in a microwave-safe bowl for 30 seconds, until warm but not boiling.
  • Add the chocolate chips, let sit for 1 minute, then stir until smooth.
  • Pour the ganache over the cake, spreading it evenly to fill the holes.
  • 4️⃣ Frost & Serve
  • Once the cake is completely cooled, spread the coconut-pecan frosting evenly on top.
  • Sprinkle with chopped pecans and toasted coconut flakes if desired.
  • Chill for at least 1 hour before serving.

Notes

For a deeper chocolate flavor, use a chocolate fudge cake mix instead.
Toasting the pecans and coconut enhances their flavor—just bake at 350°F for 5-7 minutes.
Store leftovers in an airtight container in the fridge for up to 5 days.
Freeze slices for up to 3 months and thaw in the fridge before serving.
