Top off a scoop or two of homemade ice cream with one of these gooey chocolate-chip cookies. Walnuts give this classic dessert a crunchy kick.
In a large bowl, whisk together flour, salt, and baking soda; set aside. In a medium saucepan over medium heat, melt butter. Turn off heat and add both sugars; whisk until combined. Transfer mixture to a medium bowl, and let cool to room temperature.
Whisk egg, egg yolk, and vanilla into butter mixture. Fold in reserved flour mixture until just combined. Fold in chips and nuts. Wrap dough in plastic; refrigerate until firm, about 30 minutes.
Preheat oven to 325 degrees. Using two large spoons, place golf-ball-size mounds of dough 3 inches apart on baking sheets. Bake until cookies are golden brown and the tops no longer look wet, 12 to 14 minutes. Allow cookies to cool on baking sheet 5 minutes; transfer to a wire rack. Let cool completely before serving.
