1/2 cup vanilla frosting, divided
36 miniature semisweet chocolate chips
12 large marshmallows
1 drop each green, red and yellow food coloring, optional
1/4 cup flaked coconut
12 chocolate wafers
12 miniature peanut butter cups
12 milk chocolate kisses
For the face of each witch, place a dab of frosting on the bottom of three chocolate chips; press two for eyes and one for nose onto each marshmallow.
For hair, combine green food coloring and a drop of water in a small resealable plastic bag; add coconut and shake well. Spread a small amount of frosting on sides of marshmallows; press coconut hair into frosting. Place 3 tablespoons of frosting in a small heavy-duty resealable plastic bag; tint orange with red and yellow food coloring. Set aside.
For hats, spread some of the remaining frosting in the center of chocolate wafers; press peanut butter cups upside down into frosting. Lightly spread bottoms of chocolate kisses with frosting; place on peanut butter cups. Cut a small hole in the corner of pastry or plastic bag; insert a small star tip. Fill the bag with frosting and pipe stars around the base of each peanut butter cup. Secure a hat to each witch with a dab of frosting.
