- Bake the cake in a 9x13 inch pan according to the package instructions. Let it cool slightly. 
- While the cake is still warm, poke holes all over the top using the handle of a wooden spoon. 
- Pour the crushed pineapple (with juice) evenly over the cake. 
- Next, pour the cream of coconut over the pineapple layer. Use a spatula to spread it around and help it soak in. 
- Once the cake is completely cool, spread the whipped topping over the entire surface. 
- Sprinkle the shredded coconut evenly on top. 
- Chill the cake for at least 2 hours, or overnight if you can wait that long. Serve cold.
