Preheat oven to 350. Grease a 9 x 13 inch glass baking dish with cooking oil spray. Break 1 egg into a large mixing bowl and beat lightly. Add the dry cake mix, butter, oil, and water and mix with a fork. Batter will be dense and on the dry side. Stir in white chocolate chips. Put batter into baking dish and pat out into an even layer using your fingers.

Make the second layer by beating the cream cheese with the sugar in a medium bowl. Add vanilla, eggs, and lemon juice. Add cookies and stir with a spoon. Spread the cream cheese mixture over top of first layer. Bake for approximately 30 minutes, or until it looks set and just starting to brown around the edges. Remove from oven and cool completely on a wire rack.

Make glaze by mixing the powdered sugar and butter. Add enough lemon juice to form the consistency of thick frosting. Mix in yellow food coloring and cream cheese, stir until smooth and incorporated. Cover cooled cake with glaze and place pan in refrigerator to set before cutting. Cut into bite size squares for serving. Makes about 36 bite size squares.
