Step 1

Heat oven to 350°F. With floured fingers, press cookie dough into bottom of ungreased 13x9-inch pan. (DO NOT EAT RAW COOKIE DOUGH AFTER PRESSING DOUGH IN PAN WITH FLOURED FINGERS.) Bake 13 to 16 minutes or until golden brown. Cool on cooling rack 10 minutes. In medium bowl, beat milk and pudding mix with whisk 2 minutes. Refrigerate.

Step 2

In small saucepan over medium heat, heat 3/4 cup whipping cream to boiling. Remove from heat; stir in chocolate chips until melted. Set aside. In chilled bowl, beat remaining 1 cup whipping cream and powdered sugar with electric mixer on high until stiff peaks form.

Step 3

Spread 1/2 cup chocolate mixture over crust; freeze 5 to 7 minutes or until set. Spread 1 1/2 cups pudding over chocolate layer. Arrange vanilla wafers on top in 5 rows by 8 rows. Spread with 1/2 cup of the chocolate mixture. Drop whipped cream by spoonfuls on top of chocolate; spread to edges of pan. Top with remaining pudding; spread to edges of pan. Drizzle with remaining chocolate mixture. Cover with foil; chill at least 2 hours. Cut with non-serrated knife dipped in hot water.
