2/3 cup firmly packed light brown sugar

1 large egg
1 tablespoon grated orange rind
2 teaspoons orange extract
2-1/4 cups all-purpose flour
3/4 teaspoon baking soda
1/2 teaspoon salt
12 ounces (2 cups) white chocolate chips
Beat butter and sugars at medium speed with an electric mixer until creamy. Add egg, orange rind and extract, beating until blended. Combine flour, baking soda and salt; gradually add to sugar mixture, beating until just blended. Stir in chocolate chips.
