2 cups powdered sugar
1-1/2 cups NABISCO Graham Cracker Crumbs
1 cup PLANTERS Creamy Peanut Butter
1-1/2 pkg. (8 squares each) BAKER'S Semi-Sweet Chocolate (12 squares), melted
LINE 13x9-inch pan with foil, with ends of foil extending over sides of pan.
MELT butter in large microwaveable bowl on HIGH 45 sec. Add next 3 ingredients; mix well. Spread into prepared pan; cover with chocolate.
CUT partially through dessert to mark 48 squares. Refrigerate 1 hour or until firm. Use foil handles to remove dessert from pan; cut into squares.
UPDATE: Made these and they were good but ended up breaking into uneven pieces when I cut them - broke apart like brickle
