Butter or nonstick spray a square baking dish and set oven temperature to 350º F.
After greasing the baking dish, pour the lemon pie filling into the bottom and spread it out to cover the edges.

Distribute half of the cake mix equally over the top, followed by the cubed cream cheese. Finally, top with the remaining cake mix.
Spread thinly cut butter pats over the cake batter in a single layer, being sure to cover most of the cake’s surface.
After 35 to 40 minutes in the oven, or until a toothpick inserted in the middle comes out clean, remove the baking dish from the oven.
Allow to cool for fifteen to twenty minutes after removing from oven.
