Marbled Chocolate Treats

8 1/2 honey graham crackers, broken in half

6 squares semisweet baking chocolate

1/2 cup creamy peanut butter

3 squares white baking chocolate

Line 13x9 pan with foil, with ends of foil extending over sides of pan.  Arrange grahams on bottom of pan, cutting as needed to completely cover bottom of pan; set aside.  Microwave semisweet chocolate and peanut butter in bowl on high for 1 1/2 to 2 minutes or until chocolate is completely melted when stirred, stirring every 30 seconds.  Stir until well blended.  Pour over grahams; spread with spatula to cover completely.  Repeat microwave melting steps with the white chocolate.  Droop spoonfuls of the white chocolate over chocolate covered grahams.  Immediately cut through the chocolate mixtures with knife several times for tiger stripe effect.  Refrigerate at least 1 hour or until firm.  Use foil handles to remove dessert from pan.  Peel off foil.  Cut into bars.   Store in tightly covered container in refrigerator.
