Peanut Butter Pie Cookies

Directions

1. Preheat oven to 350°. For filling, in a small bowl, beat the first 5 ingredients until smooth; set aside.
2. For cookies, in a large bowl, cream butter and brown sugar until light and fluffy, 3-4 minutes. Beat in egg white. In another bowl, mix crushed cookies, flour and baking powder; gradually beat into creamed mixture.
3. Shape rounded tablespoons of dough into 1-1/2-in. balls; place 2-in. apart on ungreased baking sheets. Flatten slightly to 1/2-in. thickness. Press a deep indentation in center of each with your thumb. Fill each with 1 rounded teaspoon filling.
4. Bake 10-12 minutes or until filling is almost set. Cool on pan 5 minutes. Remove to wire racks to cool completely.
5. Drizzle generously with melted chocolate. If desired, sprinkle with confectioners' sugar. Refrigerate leftovers.
