3/4 cups firmly packed brown sugar
1/2 cup granulated sugar
1 cup sweet butter, softened
2 eggs
1 teaspoon vanilla extract
2 1/3 cups flour
1 teaspoon baking soda
1/2 teaspoon salt
2 (1 ounce) squares semisweet baking
    chocolate, melted and cooled

Preheat oven to 375 degrees F.

In a large mixing bowl, combine brown sugar, sugar and butter, beating on medium speed and scraping bowl often until creamy, 1 to 3 minutes.

Reduce speed to low and add flour, baking soda and salt, beating and scraping bowl until totally combined 1 to 3 minutes.

Pour cooled chocolate over cookie dough and swirl with a knife or this spatula to create a marbled dough. (Do not overmix - you want a marbled effect.)

Drop dough 2 inches apart onto ungreased cookie sheets and bake 11 to 13 minutes or until lightly browned. Let stand 1 minute on cookie sheet.

Remove from sheet onto a wire rack.
