Position an oven rack in the center and preheat oven to 350F degrees. Lightly grease a 9 x 13-inch baking pan and set it aside.
In a large bowl, mix together the dry cake mix, egg, and oil until crumbly. Set aside 1 cup to use for a topping.
Press the remaining dough into the prepared pan. Bake in the center of the oven for 15 minutes. Remove from the oven and place on a wire rack.
While the crust is baking, prepare the topping. In another bowl, beat together the cream cheese, sugar, lemon juice, lemon zest, and egg until smooth and creamy.
Spread evenly over the baked crust. Sprinkle evenly with the reserved dough mixture.
Bake an additional 15 minutes, until just set. Remove from the oven and place on a wire rack to cool completely.

I like the idea of using fewer artificial colors, flavors and ingredients wherever I can.
