Step 1: Prepare the Cake

1. Preheat the oven to 350°F (175°C).
2. Grease and flour a 9×13-inch baking pan.
3. In a mixing bowl, combine the cake mix, coconut milk, vegetable oil, and eggs. Mix until smooth.
4. Pour the batter into the prepared pan and smooth the top.
5. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.
6. Allow the cake to cool completely before proceeding.

Step 2: Add the Coconut Soak

1. In a bowl, whisk together the cream of coconut and sweetened condensed milk.
2. Use a straw or skewer to poke holes all over the cake.
3. Slowly pour the coconut soak over the cake, allowing it to absorb fully.
4. Let sit for 15-20 minutes before adding the topping.

Step 3: Finish with Toppings

1. Spread the thawed whipped topping evenly over the cake.
2. Sprinkle flaked coconut generously on top.

Step 4: Chill & Serve

1. Cover and refrigerate for at least 4 hours (overnight is best).
2. Slice and serve chilled for the best flavor.
