One Nutty Date

Preheat oven to 375°F. Beat brown sugar, butter, peanut butter and cinnamon in a large bowl with an electric mixer on medium speed until well mixed. Add egg and vanilla; continue beating until well mixed. Reduce speed to low. Add flour, baking powder, baking soda and salt; beat until well mixed, scraping the sides of the bowl as necessary. Stir in dates and walnuts. Refrigerate the dough for at least 1 hour before baking. Use a small scoop (1 3/8- to 1 1/2-inch) and drop balls of dough 2 inches apart onto an ungreased baking sheet. (If you do not have a scoop, shape the dough by hand into 1- to 1 1/4-inch balls.) Gently press each ball to flatten slightly. Bake the cookies until the edges are lightly browned, 8 to 10 minutes. Transfer to a wire rack to cool completely. To decorate: Place white chocolate and oil in a small microwave-safe bowl and microwave on Medium, stirring every 30 seconds, until the chocolate is melted and smooth. To drizzle, dip a fork in the chocolate then wave it over a cookie to create a lacy finish (see Variations). Let the chocolate set for at least 1 hour. Variations: Instead of drizzling, dip the top side of the cooled cookies in melted white or dark chocolate and sprinkle with chopped walnuts.
