  • 1 21 oz can lemon pie filling
  • 1 15 oz box lemon cake mix (or yellow cake mix + 1 tbsp lemon zest)
  • ½ cup 1 stick unsalted butter, melted
  • ½ cup sweetened condensed milk optional, for extra creaminess

Instructions
 

Preheat Oven: Heat to 350°F. Grease a 9x13-inch baking dish.

    Layer 1: Spread lemon pie filling evenly in the dish. Drizzle condensed milk on top (if using).

      Layer 2: Sprinkle dry cake mix over the filling. Do not stir!

        Layer 3: Drizzle melted butter evenly over the cake mix.

          Bake: 40-45 minutes until golden and bubbly at the edges.

            Cool & Top: Let cool 10 minutes, then add your favorite toppings.

              Notes

              • Make it 3-Ingredient: Skip the condensed milk for a simpler version.
              • Cream Cheese Twist: Add a layer of softened cream cheese mixed with ¼ cup sugar under the pie filling.
              • Storage: Refrigerate leftovers for up to 3 days. Freeze slices for 2 months.
