Line a large baking sheet with foil. In a large zip top bag add the gelatin and confectioners' sugar. Mix to combine and set aside. Measure the cereal into a large bowl. Keep the candy in the tray it comes in and place in the microwave. Microwave 1 minute, stir and heat an additional minute. Pour melted chocolate over cereal and stir until cereal is completely coated. Dump into the bag with the confectioners' sugar mixture, shake until all the cereal is coated. Pour onto the large foil covered pan until set. Store in a covered container up to 2 weeks.
