Preheat oven to 350 degrees. Grease and flour a 23 cm tube pan. Cut each sandwich cookie into quarters. In a large bowl, with mixer at low speed, beat flour and remaining ingredients (except cookies and Glaze) until blended. Increase speed to High; beat 2 minutes, scraping bowl a few times. Spoon about 0.75 cup batter into pan. Gently stir cut-up cookies into remaining batter, and spoon into same pan. Bake 50 minutes, or until cake springs back when lightly touched (toothpick test will not work). Cool cake in pan on wire rack 10 minutes; remove from pan; cool completely on rack. When cake is cool, prepare Chocolate Glaze. In a 1 litre saucepan, over low heat, heat all ingredients, stirring constantly, until melted and smooth. Drizzle over cake. ----
