2 cups all-purpose flour
1/2 teaspoons baking soda
1/2 teaspoons salt
3/4 cup unsalted butter, melted
1 cup packed brown sugar
1/2 cups white sugar
1 tablespoon vanilla extract
1 egg yolk
2 cups semisweet chocolate chips (I like to use milk chocolate)
Preheat the oven to 325 degrees F (165 degrees C). Grease cookie sheets or line with parchment paper.
Sift together the flour, baking soda & salt; set aside.
Mix in the sifted ingredients until just blended. Stir in the chocolate chips by hand using a wooden spoon.
Drop cookie dough 1/4 cup at a time onto the prepared cookie sheets. Cookies should be about 3 inches apart.
Bake for 15 to 17 minutes in the preheated oven, or until the edges are lightly toasted. Cool on baking sheets for a few minutes before transferring to wire racks to cool completely.
