Line a 9x13 inch pan with foil and spray with nonstick cooking spray.
Mix together 2 egg yolks with 1 teaspoon of cold water.
Mix together shortening, granulated sugar, white sugar, egg yolks, baking soda and flour.
Press the dough into the prepared 9×13 inch pan.
Middle Layer:
Sprinkle with cinnamon chips and gently press them into the bottom layer.
Top Layer:
Beat egg whites until soft peaks form.
Add brown sugar and beat until stiff peaks form.
Carefully spread the meringue over the cinnamon chip layer without allowing it to touch the sides of the pan. To make this step easier, I spooned the meringue into the pan in several dollops and then spread each of them out.
