I LOVE making these at Christmas time, it is such a break from the chocolate, peppermint coma that can come with the Christmas season. I try to throw in a few citrus treats to keep things fresh. It's really important not to get the "pith" when zesting, it can give the goodies a bitter taste. This recipe can also be adapted to make a "Chocolate Orange Cookie" simply by replacing the white chocolate chips with milk/semi-sweet chips.
1Preheat oven to 375 degrees. In a small bowl, combine flour, baking soda, and salt; set aside.
2In a large bowl, cream butter and sugars until light and creamy. Beat in egg, vanilla and orange extract until smooth. Gradually add flour mixture until combined. Stir in orange zest and chocolate chips.
3Drop rounded teaspoonfuls onto ungreased cookie sheets. Do not flatten cookies; it will make them dry. Bake 8 - 10 minutes or until golden brown around edges. Do not overbake!
4Cool for several minutes on cookie sheets before transferring to rack to cool completely.
