Line 2 baking sheets with parchment paper.

In a large saucepan over low heat, melt the butter. Add the mini marshmallows and stir until melted and smooth. Stir in the green food coloring.

Add the cornflakes to the melted marshmallow mixture, stirring gently to coat. Let it cool slightly.

Spray your hands with nonstick cooking spray. Take about 1/3 cup of the mixture and form it into a circular wreath. Place it onto the prepared baking sheet. Repeat with remaining mixture.

Place 3 small red cinnamon candies on each wreath. Let the wreaths sit at room temperature for about 15 minutes or until firm.
