• 2 cups flour
• 1/ 2 teaspoon baking soda
• 6 ounces unsalted butter, melted
• 1 cup packed dark brown sugar
• 1/ 2 cup white sugar
• 1 egg
• 1 egg yolk
• 2 teaspoons vanilla
• 2 cups chocolate chips

Method

• Step 1

  Preheat oven to 325F (160C) and Line cookie sheets with parchment paper.

• Step 2

  With a mixer, mix butter, both sugars and salt. Whip in the egg, yolk and vanilla. Gently mix in flour and soda (do not overmix). Add chocolate chips.

• Step 3

  Using a 2 inch spring loaded ice cream scoop, scoop cookie dough onto sheets, placing at least 2 inches apart (cookies spread considerably). Bake for 15-18 min. They should still be very soft in the center. Do not over bake as the cookies will be crispy rather than soft. Cool on rack.
