Description

A nostalgic and moist pistachio cake studded with pineapple and topped with a fluffy pudding-whipped frosting and crunchy pecans.


Ingredients

Scale
  • 1 box pistachio cake mix
  • 1 cup club soda
  • 1/2 cup vegetable oil
  • 3 eggs
  • 1 cup crushed pineapple, drained
  • 1 cup whipped topping (thawed if frozen)
  • 1/2 cup chopped pecans
  • 1 box instant pistachio pudding mix

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and lightly flour a 9×13-inch baking pan.
  2. Combine the pistachio cake mix, 1 cup club soda, 1/2 cup vegetable oil, and 3 eggs in a large bowl and whisk until uniform.
  3. Fold in the drained crushed pineapple gently with a rubber spatula.
  4. Pour the batter into the prepared pan and smooth the top. Bake for 30–35 minutes.
  5. Transfer the pan to a wire rack and let the cake cool completely.
  6. Mix 1 cup whipped topping with the instant pistachio pudding mix until smooth.
  7. Spread the pudding-whipped frosting evenly over the cooled cake and sprinkle with chopped pecans.
  8. Refrigerate the cake for at least 1 hour before slicing and serving.

Notes

Ensure to drain the pineapple well to avoid a soggy cake. Refrigerate leftovers for up to 5 days.
