Preparation

• Line 13x9-inch pan with foil, with ends of foil extending over sides.  Separate 12 cookies to make 24 halves; place, top sides down, in single layer on bottom of prepared pan.
• Melt 8 oz. chocolate as directed on package; spread over cookies in pan until completely covered.  Refrigerate 10 min. or until chocolate is firm.
• Chop 4 of the remaining cookies; reserve for later use.  Crush remaining cookies into fine crumbs.
• Beat peanut butter and butter in medium bowl with mixer until blended.  Add cookie crumbs; mix well.  Gradually beat in sugar.  Drop peanut butter mixture by large spoonfuls over chocolate layer in pan; spread to evenly cover chocolate.
• Chop remaining chocolate; place in microwaveable bowl.  Add cream.  Microwave on HIGH 1 to 1-1/2 min. or until chocolate is completely melted and mixture is well blended, stirring every 30 sec.  Cool 15 min., stirring occasionally until chocolate mixture is thickened.
• Spread chocolate mixture evenly over peanut butter layer; sprinkle with reserved chopped cookies.  Refrigerate 4 hours.  Use foil handles to remove dessert from pan before cutting into bars.
