Best Chocolate Chip Cookie

I have tried so many recipes for chocolate chip cookies - these are the BEST!!

Ingredients

2 cups all-purpose flour

1/2 teaspoon baking soda

1/2 teaspoon salt

3/4 cup unsalted butter, melted

1 cup packed brown sugar

1/2 cup white sugar

1 tablespoon vanilla extract

1 egg

1 egg yolk

1 2/3 cups semisweet chocolate chips

Directions - yields 2 dozen cookies

1. Preheat the oven to 325 degrees F (165 degrees C). Grease cookie sheets or line with parchment paper.
2. Sift together the flour, baking soda and salt; set aside.
3. In a medium bowl, cream together the melted butter, brown sugar and white sugar until well blended. Beat in the vanilla, egg, and egg yolk until light and creamy. Mix in the sifted ingredients until just blended. Stir in the chocolate chips by hand using a wooden spoon. Drop cookies (I use tablespoon) onto greased pan.
4. Bake for 9-11 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.
