1-First Step: Get the oven and pan ready Preheat your oven to 350 degrees Fahrenheit. While it heats, spray a 9×13 pan with cooking spray so the cake releases easily after baking. This small step helps prevent sticking and makes serving much easier later on.

2-Second Step: Mix the cake batter In a large mixing bowl, combine the yellow cake mix, 4 eggs, 1/2 cup vegetable oil, and 1 can of crushed pineapple with its juice. Stir until everything is well blended. The batter will look thick and fruity, and that is exactly what you want. The pineapple juice adds moisture, so do not drain it.

3-Third Step: Bake the cake Pour the batter into the prepared 9×13 pan and smooth the top with a spatula. Bake for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean. If the toothpick has wet batter on it, give the cake a few more minutes.

4-Fourth Step: Cool it completely Set the cake on a wire rack and let it cool completely before adding the frosting. This matters more than folks think. If the cake is still warm, the topping can melt and slide around, which is a mess nobody wants.

5-Fifth Step: Make the frosting In a medium bowl, fold together the thawed whipped topping, instant vanilla pudding, and 1 can of crushed pineapple with its juice. Fold gently instead of stirring hard so the topping stays light and fluffy. The pudding helps it thicken while the pineapple keeps the flavor bright and fresh.

6-Final Step: Frost and serve Spread the frosting over the cooled cake in an even layer. If you want, reserve a little pineapple to sprinkle on top for a pretty finish. Toasted coconut also makes a lovely topping if you are after a little extra texture. Chill the cake for a bit before serving if you like a firmer frosting, or serve it right away for a softer, creamier bite.
