In a small bowl mix all purpose flour and baking soda together with a fork and set aside.
In another small bowl, mix cinnamon and sugar for topping and set aside.
Take a big bowl and add butter + sugar to it. Beat them together with electric beater till the mix is pale light in color, for about 2 minutes.
Add salt, egg substitute and vanilla extract to the mix. Beat them together for another 30-40 seconds.
Now add all purpose flour mix to the batter. Take a wooden spoon or fork and mix all the ingredients together till there is no dry ingredient left from mixing.
It will form a thick dough.
Transfer this dough to the prepared greased baking pan and spread it out with evenly in the pan.
Sprinkle evenly with generous amount of cinnamon sugar mix.
Bake it for 25-30 minutes, till the cookie dough is set and edges are slightly golden brown.
DO NOT OVER-BAKE or the cookie bars will be tough.
Take the pan out of the oven and let stand for 7-8 minutes.
Now take a knife and cut the baked large cookie square into small or large pieces of your choice. I cut out 16 squares out of that.
Eat these fresh.
OR store them in air tight container, once completely cooled down.
