In a large bowl, whisk together the flour, salt, and baking soda.
Brown the butter over medium heat, stirring consistently until browned.
Turn off the heat and set the butter aside to cool to room temperature.
Make the espresso (We used espresso beans, grinded it up into espresso powder, and used a moka pot to turn into liquid espresso- not powder)
In a large mixing bowl combine the sugars, the egg yolks, the whole egg, the melter butter, and the vanilla extract.
With an electric mixer, beat until pale golden color, and thick consistency.
Mix the dry ingredient with the wet ingredients (adding the wet ingredients slowly into the dry ingredients)
Add the espresso and continue mixing.
Fold in the chocolate chips until everything is combined.
Work the dough into a long disk and wrap in plastic wrap.
Refrigerate the dough for 2 hours or overnight.
When you are ready to bake the cookies preheat the oven to 350° F and line a cookie sheet with parchment paper (if you have two cookie sheets, prep the both of them). Spray the baking sheet with baking spray. Cut the dough into 1 inch disks.
Roll out the dough with your clean hands into walnut size pieces.
Place balls 2 inches apart on parchment line paper.
Bake for 10-12 minutes, or until golden brown. Set your timer for 10 minutes and check the cookies (every oven is different and yours may be ready at 10 minutes).
Cool completely and store in an airtight container. ENJOY!
