Prepare a piece of greased wax paper and set it aside.
Add the marshmallows and butter to a large microwave-safe dish. Microwave for 2 minutes. Stir and heat for 2 more minutes.
Working quickly add the green coloring and extracts. Stir, then add the cornflakes. Mix until evenly coated.
Scoop a spoonful of the mixture and drop it in clumps on the wax paper. To make a wreath shape lightly grease your fingers and form a hole in the center of each clump. Add several red hots to the newly shaped wreath.
Lightly grease a storage container. Allow the treats to cool and set before transferring them to the container.
Makes 8-10 wreaths.
Notes
Store the cookies for 5-7 days in a lightly greased airtight container, separating layers with wax paper, or wrap each cookie and freeze together in a freezer Ziploc for 4-6 weeks.
