Line 2 baking sheets with parchment paper.

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

Add the cornflakes to the melted marshmallow mixture and gently stir until well coated. Let it cool slightly.

Spray hands with nonstick cooking spray. Take about 1/3 cup of the cornflake mixture and form it into a log shape, connecting the ends to form a circular wreath. Place it onto the prepared baking sheet. Repeat with the 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.
