Pour the cereal into a large bowl. Set aside.

In 20 second increments, melt the candy melts or white chocolate in a medium microwave-safe bowl. Stir after each increment until melted and completely smooth. Stir in 2 teaspoons of cinnamon, the nutmeg, cloves, and allspice until combined. Pour mixture over cereal and toss gently to coat each square. Be gentle, the squares break easily.

Pour the confectioners’ sugar and 1 teaspoon of cinnamon into a large zipped-top bag. Add the coated cereal and shake until each piece is coated. Pour back into a large bowl and discard excess confectioners’ sugar. Toss in the mellowcreme pumpkins. Use 1-2 cups, whatever amount you prefer.
