here is a recipe i have saved for years and was actually published by Martha as dessert of the month for July 2002.
this super size chocolate chip cookie is both soft and tasty. after baked, this cookie is absolutely delicious served warm with a scoop of vanilla ice cream.
preheat the oven to 350 degrees. in a medium bowl, mix 2 cups flour, 1 teaspoon baking soda, and 1/2 teaspoon salt. then, in a bowl of an electric mixer, cream 3/4 cup unsalted butter, 1/4 cup sugar, 3/4 cup light brown sugar, until creamy and fluffy for about 2 minutes.
then, add 1 large egg and 2 teaspoons of vanilla. mix well. then, add the flour mixture and beat until combined. stir in 1 1/2 cups of chocolate chips. i used a mixture of milk and semi sweet chips. transfer the dough into a 10 inch ovenproof skillet, and press to flatten. bake for 40 minutes. cool for about 20 minutes before removing from the pan.
