Prepare cake batter according package directions. Fill 24 greased or lined muffin cups. Bake at 350 degrees Fahrenheit for 21-26 minutes. Cool 5 minutes in pan; transfer to wire rack to finish cooling.
Combine sugar, cocoa, butter, and milk in small pot. Bring to a boil on medium heat, stirring constantly. Remove from heat, stir in vanilla. Cool to 110°F.
Beat with wooden spoon until thick and losing gloss, about 8 minutes. Cut marshmallows in half width wise; place 1/2 on each cupcake. Frost marshmallows and tops of cupcakes. Dip in sprinkles.
Place dab of frosting on each M&M and press on to look like eyes. Using skewers, poke 4 holes on each side of each cupcake. Insert a piece of licorice into each hole.
