Preheat the oven to 350°F (175°C). Line the baking pan with parchment paper or spray with non-stick spray.
In a large mixing bowl, combine the sifted flour, sugar, and salt. Stir until evenly mixed.
Add the melted butter, cold brew coffee, and vanilla extract to the dry ingredients. Mix with a spatula until the dough becomes cohesive and slightly sticky.
Fold in the chocolate chips until evenly dispersed throughout the dough.
Transfer the dough to the prepared baking pan. Use a spatula or your hands to press and spread the dough evenly across the pan's surface.
Bake in the preheated oven for 20-25 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out with moist crumbs. Remove from oven and cool slightly before cutting into bars.
