Remove 1 2/3 cup of that mixture and set it aside.
Add egg to to remaining mixture (the larger amount), blending until crumbly. Press that mixture into the bottom of a 9x13 pan.
Gently spoon lemon mixture on top, spreading it out evenly.
Add the reserved 1/3 cup of white chocolate chips to the reserved crumb mixture and sprinkle that over the lemon layer.
Press that lightly into the lemon layer and bake for 20-25 minutes, or until lightly browned. Cool in the pan on wire rack.
While that is cooling, take the last of the chocolate chips and melt in the microwave, starting at 30 seconds, stirring after every interval until smooth. Drizzle that onto the bars.
While not easy to cut and serve while warm, they are even more amazing!
