Ingredients
For the Cake
- 1 box yellow cake mix (15.25 ounces)
- 1 box instant vanilla pudding mix (3.4 ounces), divided use
- 1 can crushed pineapple (20 ounces), divided use, do not drain
- 4 large eggs
- ½ cup vegetable oil
For the Frosting
- 8 ounces Cool Whip, thawed
- 1 jar marshmallow fluff (7 ounces)
- Reserved 2 tablespoons instant vanilla pudding mix
- Reserved ½ can crushed pineapple (do not drain)
Instructions
- Preheat and Prepare Pan: Preheat the oven to 350°F (175°C). Spray a 9×13-inch baking pan with nonstick cooking spray and set aside.
- Mix Dry Ingredients: In a large bowl, combine the yellow cake mix with all but 2 tablespoons of the instant vanilla pudding mix. Set aside the reserved 2 tablespoons of pudding mix for the frosting.
- Add Wet Ingredients and Pineapple: Remove half of the can of crushed pineapple (reserve this half for the frosting). Add the remaining crushed pineapple along with the 4 beaten eggs and ½ cup vegetable oil to the cake mix mixture. Use an electric hand mixer on medium speed to blend until fully combined.
- Bake the Cake: Pour the batter evenly into the prepared baking pan. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center of the cake comes out clean.
- Cool the Cake: Remove the cake from the oven and transfer to a wire rack. Allow it to cool completely before frosting.
- Prepare Frosting: In a mixing bowl, combine the thawed Cool Whip and marshmallow fluff until smooth and fluffy. Stir together the reserved 2 tablespoons of pudding mix and the reserved half can of crushed pineapple, then fold this mixture into the Cool Whip and marshmallow fluff blend until well incorporated.
- Frost and Chill: Spread the pineapple frosting evenly over the cooled cake. Cover the cake and refrigerate for at least 3 hours to allow the frosting to set and flavors to meld.
Notes
- Do not drain the crushed pineapple; the juice adds moisture to both the cake and frosting.
- For best results, allow the cake to cool completely before applying the frosting to prevent melting.
- Refrigeration is essential for the frosting to set and the cake to achieve the ideal texture.
- Use an electric hand mixer to ensure even mixing for a light, consistent batter.
- Store leftover cake in the refrigerator and consume within 3-4 days for optimal freshness.
