Beat in the egg until batter is smooth and fluffy again.
Stir in the dry ingredients until almost fully combined.
Mix in the chocolate chips until evenly distributed.
Scoop and tray on parchment paper lined baking sheets.
Chill or freeze dough balls, or top with salt and chocolate garnish to bake right away.
Bake until edges are golden brown, but the centers are still a little pale.
