In a saucepan, heat the milk and butter, stirring frequently until the butter has melted.
Remove from heat.
Add the confectioner’s sugar and mix thoroughly.
Mix in the oil of peppermint.
As soon as it is cool enough to work with, knead with your hands until the fondant is smooth.
Take about 1/6 of the fondant, and add green food coloring. Knead to mix color evenly.
Cover with a damp cheesecloth, to prevent drying.
To the remaining fondant, add enough yellow and red food coloring to make it an orange pumpkin color. Cover with damp cheesecloth.
Working with a small amount of the orange-colored fondant at a time, roll into small balls in the palms of your hands.
Using a toothpick, make grooves in the fondant ball, to resemble the “ribs” in a pumpkin.
Roll a small piece of the green fondant in thin cylinders and cut it into short stem-like pieces.
Press the “stem” onto the top of each pumpkin.
