This easy lemon dump cake layers bright lemon pie filling, juicy crushed pineapple, and lemonade concentrate beneath a buttery lemon cake-mix topping. Bake until golden, then finish with powdered sugar and serve with whipped topping for a sunny, tangy dessert.

Ingredients

For the Cake

  • 21 ounces canned lemon pie filling
  • 20 ounces canned crushed pineapple, undrained
  • 1/2 cup frozen lemonade concentrate, thawed
  • 15 1/4 ounces lemon cake mix
  • 3/4 cup unsalted butter, melted, plus extra for greasing
  • 1 tablespoon fresh lemon zest

For Serving

  • 1/4 cup powdered sugar
  • Whipped topping, as desired
  • Yellow sanding sugar, as desired

Instructions

  1. Prepare the oven and pan.

    Preheat the oven to 350°F. Lightly grease a 9 x 13-inch baking dish with butter.

  2. Add the lemon filling.

    Spread the lemon pie filling evenly over the bottom of the prepared dish.

  3. Layer the pineapple and lemonade.

    Spoon the undrained crushed pineapple evenly over the lemon filling, then drizzle the thawed lemonade concentrate over the pineapple.

  4. Add the cake mix.

    Sprinkle the lemon cake mix evenly over the fruit layer.

  5. Top with butter and zest.

    Slowly pour the melted butter over the cake mix, distributing it as evenly as possible. Sprinkle the lemon zest over the top.

  6. Bake the cake.

    Bake for 45 to 48 minutes, until the top is golden and the cake is baked through.

  7. Cool and serve.

    Cool for 15 to 20 minutes, then dust with powdered sugar. Slice and serve with whipped topping and yellow sanding sugar, if desired.

Notes

  • Use the pineapple undrained; its juice helps keep the fruit layer moist.
  • Pour the melted butter slowly and try to cover as much of the cake mix as possible for a more even topping.
  • Let the cake rest before slicing so the filling can settle.
  • Whipped topping and yellow sanding sugar are optional garnishes.
  • Nutrition is an estimate per serving and does not include optional garnishes.
