Ingredients

2 1/4 cups all-purpose flour (about 10 ounces)

1 teaspoon baking soda

1/4 teaspoon salt

1 cup packed brown sugar

3/4 cup granulated sugar

1/2 cup butter, softened

1 teaspoon vanilla extract

2 large egg whites

3/4 cup semisweet chocolate chips

Cooking spray

Preparation

Preheat oven to 350°.

Lightly spoon flour into dry measuring cups; level with a knife. Combine flour, baking soda, and salt, stirring with a whisk.

Combine sugars and butter in a large bowl; beat with a mixer at medium speed until well blended. Add vanilla and egg whites; beat 1 minute. Add flour mixture and chips; beat until blended.

Drop dough by level tablespoons 2 inches apart onto baking sheets coated with cooking spray. Bake at 350° for 10 minutes or until lightly browned. Cool on pans for 2 minutes. Remove from pans; cool completely on wire racks.
