Turn your oven on to 350°F. Give a 9x13-inch baking pan a good coat of cooking spray.
02 -
Grab a big bowl and use your mixer (hand or stand) to beat together the cake mix, eggs, milk, melted butter and sour cream. Beat for about 2 minutes until everything's well combined.
03 -
Empty your cake mix into your greased pan. Pop it in the oven for 25-30 minutes. It's done when it bounces back after a light touch or when a toothpick comes out clean from the middle. Let it sit for about 5 minutes after baking.

Take a wooden spoon handle and make deep holes all over the cake in neat rows. These will hold your pudding.
05 -
In another bowl, mix the pudding powder, cold milk, and 1 cup of pineapple with its juice. Stir until it starts to get thick.
06 -
Pour your pudding mix into all the holes. Use a spatula to push it down and make sure they're totally filled. Spread any leftover pudding across the cake's surface.
07 -
Strain the juice from your remaining pineapple and spread these crushed bits across the top of the pudding.
08 -
Now spread your whipped topping all over the pineapple in an even layer.
09 -
Loosely cover your dessert with plastic wrap and stick it in the fridge for 3-4 hours or leave it overnight. This wait makes it taste way better.

Slice into portions and add fresh pineapple chunks or toasted coconut on top if you want.
