Preheat your oven to 375°F and prepare cookie sheets with parchment paper or a silicone mat.
Combine the flour, salt, baking soda and cinnamon in a bowl and stir to combine. Set aside.
In a separate bowl add the sugars, butter, and applesauce and stir together. Then add the beaten eggs and continue to combine the wet ingredients.
Add the dry ingredients to the wet ingredients and fully combine. Then, add the rest of the goodies and stir to mix in.
Use a cookie scoop or spoon and place the dough on your cookie sheet. Make sure you leave room for them to spread. I was able to fit 6 balls/sheet. Bake for 10-12 minutes until they start to brown on the edges. Remove the cookies from the oven and place on a cooling rack. If you are adding flaked salt to the top, add it right after they come out of the oven. It's always recommended to eat at least one while they are warm ?!
