Chocolate Icebox Cookies

1 stick unsalted butter -- softened

1/2 cup light brown sugar

1/3 cup granulated sugar

1 large egg

1 teaspoon vanilla

2 ounces unsweetened chocolate -- melted & cooled

1 3/4 cups flour

1/2 teaspoon baking soda

1/8 teaspoon salt

In a large bowl, beat the butter until fluffy. Add the brown sugar and granulated sugar and beat until well blended. Add the egg and vanilla and beat until thickened. Beat in the melted chocolate, then add 3/4 cup of the flour along with the baking soda and salt. Stir in the remaining 1 cup flour to make a soft dough.

Divide dough in half. Wrap each half in plastic wrap and shape it into a 6" log. Refrigerate until firm. (Can be stored in a plastic bag and refrigerated for up to 1 week or frozen for up to 2 months.)

Preheat oven to 350. Using a thin knife, slice each log 1/8" to 1/4" thick. Arrange the cookies 1" apart on a buttered cookie sheet and bake for 10 to 15 minutes or until lightly browned.
