Heat oven to 350℉. Grease a 9x13-inch glass pan with non stick cooking spray.
Mix the dry cake mix (do not follow directions on box), butter, egg, oil, and water together with a fork.
Then add in the white chocolate chips. Spread evenly in the greased pan. Get all the way to the edges. Set aside while you make the next layer.
For the cheesecake layer, combine the cream cheese and sugar in a medium bowl and blend together well.
Then add the vanilla, eggs and lemon juice. Stir in chopped Oreos by hand with a spoon.
Carefully spread the cream cheese layer over the lemon cake mix layer. Bake for 30 to 35 minutes. (I cooked mine for 32 minutes)
Carefully remove it from the oven to prevent it from sinking. Mine sunk just a little bit. Let it cool for about an hour.
While it is cooling you can make the glaze. For the glaze mix the powdered sugar and melted butter together.
Add enough lemon juice to form the consistency of thick frosting. Then mix in the cream cheese and yellow food color (a few drops).
Notes
You definitely do not need to use the yellow food coloring. That is obviously not going to change the flavor of the dish. It is merely for presentation. But you can always leave it out and cut up a lemon and put it on top of the glaze and use it too!
