The Best Big Fat Chewy Chocolate Chip Cookies

2 cups flour
1/2 tsp baking soda
1/2 tsp salt
3/4 c unsalted butter, melted
1 c packed brown sugar
1/2 c white sugar
1 Tbs vanilla extract
1 egg
1 egg yolk
2 cups semi sweet chocolate chips

Preheat oven to 325 degrees. Grease cookie sheet or use parchment paper. Sift together flour, baking soda and salt. Set aside. In medium bowl, cream together melted butter, brown and white sugar until well blended. Beat in vanilla, egg and egg yolk until light and creamy. Mix in dry ingredients until just blended. Stir in chocolate chips by hand. Drop cookie dough a 1/4 cup at a time onto the prepared cookie sheet. Cookies should be about 3 inches apart. Bake for 15-17 minutes or until the edges are lightly toasted. Cool on baking sheet for a few minutes before transferring to rack to cool completely. These are awesome for ice cream sandwiches!
