Lemon chess bars have a cakey crust topped with a gooey cream cheese and butter filling. They are easy to make and taste phenomenal. Make a batch to see for yourself.
In a medium bowl, stir together cake mix, one egg and one stick of melted butter. Press mixture into the bottom of the greased pan to form a crust.
In the same bowl, beat cream cheese until it is smooth and creamy. Add butter and mix to combine.
Mix in eggs, one at a time until they are incorporated. Then stir in lemon juice and powdered sugar.
Pour cream cheese mixture over the crust.
Bake for 40-45 minutes. The edges should be golden brown and set, but the center should still have a little bit of jiggle when you gently shake the pan.
Allow to cool at room temperature for at least an hour. Then serve or move to the refrigerator to chill until you are ready to serve.
Dust with powdered sugar if desired and store any leftovers in the refrigerator.
