Preheat oven to 375 F.
In a large bowl, cream together sugars, applesauce, butter, and shortening.
Stir in vanilla extract if using. Set aside.
In a seperate bowl whisk together flour, baking soda and salt.
Add dry mixture into wet mixture until a soft dough forms.
Fold in 3/4 cups chocolate chips.
Chill dough for 30 minutes. (optional but makes a chewier cookie)
Using a mini cookie scoop (about 1 tablespoon worth of dough) drop the cookies 2 inches apart. (I like to roll each ball in my hands to make them perfectly round and smooth)
Press the dough ball down gently to flatten then just a bit.
Using the remaining chocolate chips, press a few chocolate chips lightly into each ball.
Bake for 7 minutes.
Remove from oven and let cool completely whil still on the pan.
