Line a baking sheet with wax or parchment paper. Set aside. Generously butter a large spoon or spatula. Set aside.
In a large saucepan, melt the butter over medium-low heat.
Add the mini marshmallows to the saucepan and continue heating, stirring continuously, until the mixture is smooth.
Add a couple of drops of gel food coloring and stir until the color is completely incorporated.
Fold the corn flakes into the melted marshmallow mixture, stirring gently to avoid crushing the cereal.
Using the buttered spoon or spatula, drop the cornflake mixture onto the prepared baking sheet.
Gently make a spot in the center of the pile of cornflakes by pushing them to the side with the spoon. This will make the center of the wreath shape. Repeat with the rest of the mixture.
Add red jimmies. Allow to set for about 1 hour.
Notes
Storage and FreezingStore the cornflake wreaths in a single layer at room temperature in an airtight container for up to 1 week.Freeze these cookie wreaths in a freezer storage Ziploc bag for up to 3 months. Place layers of parchment or wax paper between the layers to prevent them from sticking and help them to hold their shape.
