1-First Step: Preheat your oven to 350°F. Spray a 9×13-inch pan with cooking spray so your cake comes out clean.

2-Second Step: In a large bowl, combine 1 box yellow cake mix, 4 eggs, 1/2 cup vegetable oil, and 1 (8 oz) can crushed pineapple with juice. Mix well until the batter looks smooth and evenly combined.

3-Third Step: Pour the batter into the prepared pan and spread it into an even layer.

4-Fourth Step: Bake for 25 to 30 minutes, or until a toothpick inserted into the center comes out clean.

5-Fifth Step: Cool the cake completely on a wire rack. This step matters because frosting needs a cool surface to spread properly.

6-Final Step: Make the frosting. Fold together 1 (8 oz) container whipped topping (thawed), 1 small box instant vanilla pudding, and 1 (8 oz) can crushed pineapple with juice. Spread the frosting over the cooled cake. Optionally, reserve a small amount of pineapple to sprinkle on top for extra “sunshine” vibes.
