I remember my mom making these!
It's really a simple recipe; it mimics Rice Krispie treats. You just substitute Corn Flakes for the Rice Krispies and make wreath shapes instead of just putting in a pan. Here's the recipe from Allrecipes!
1/2 cup butter
30 large marshmallows
1 1/2 tsp green food coloring
1 tsp vanilla extract
4 cups cornflakes cereal
Cinnamon red hots candies
Melt butter in large saucepan over low heat. Add marshmallows, cook until melted, stirring constantly. Remove from heat, stir in vanilla, food coloring and cornflakes. Quickly drop heaping tablespoonfuls onto wax paper and form into wreath shape with greased fingers. Immediately decorate with cinnamon candies. Allow to cool to room temperature before removing from wax paper and storing in airtight container.
