Preheat oven to 350°F (175°C). Lightly grease a 9x13-inch baking pan to prevent sticking.
02 -
In a large bowl, combine yellow cake mix and melted butter. Mix with a fork until crumbly. Press half of this mixture evenly into the bottom of the prepared pan to form a base.
03 -
Spread 1.5 to 2 cans of lemon pie filling evenly over the cake mix base, ensuring full coverage.
04 -
In a separate bowl, beat softened cream cheese with granulated sugar, egg, vanilla extract, and lemon zest until the mixture is smooth. Spread this evenly over the lemon filling.
05 -
Sprinkle the remaining cake mix and butter mixture over the cream cheese layer to create a crumble topping. Some of the cheese layer may still be visible for a rustic appearance.
06 -
Transfer the pan to the oven and bake for 35–40 minutes, or until the top is golden brown and the cream cheese layer is set.
07 -
Allow the cake to cool in the pan for at least 45 minutes to let the layers firm up. Optionally, dust with powdered sugar before slicing. Serve plain or with a scoop of vanilla ice cream, if desired.
