Giant Chocolate Chip Cookies

2 c. all-purpose flour
1/2 t. baking soda
1/2 t. salt
3/4 c. butter, melted
1 c. brown sugar, packed
1/2 c. sugar
1 egg
1 egg yolk
1 T. vanilla extract
12 oz. pkg. semi-sweet chocolate chips
 

In a bowl, combine flour, baking soda and salt; mix well and set aside. In a separate large bowl, beat together butter and sugars until well blended. Add egg, egg yolk and vanilla; beat until light and creamy. Add flour mixture to butter mixture; stir until just blended. Stir in chocolate chips. Form dough into balls by 1/4 cupfuls. Place on greased or parchment paper-lined baking sheets, 2 inches apart. Bake at 325 degrees for 15 to 17 minutes, until edges are golden. Cool cookies on baking sheets for several minutes; remove to wire racks. Makes about 15 cookies.
