Remove from heat; stir in cereal, graham crackers, 1 cup almonds and 1 cup chocolate chunks. Press mixture into a lightly greased 13x9-in. baking pan, using waxed paper or a lightly greased spatula. Cool to room temperature. Melt 1 package chocolate chunks in microwave; spread over top. Sprinkle with remaining package of marshmallows and the remaining almonds and chocolate chunks. If desired, toast marshmallows using a kitchen torch. Cut into bars.
