Hi Kathy,
This is pretty much the self filled cupcakes but with a twist for Halloween.

1 box of Dark Choc. Cake Mix(or your favorite homemade cake)
8 oz. cream cheese, softened
1 egg
1/3 cup sugar
Yellow and red food coloring
6 oz. choc.chips
Your favorite frosting (homemade or from a can)

Prepare cake mix or cake batter and spoon into paper lined cupcake tins about
half full with batter. Blend cream cheese,egg, sugar until smooth. Add 2 drops
red food coloring and 1 drop yellow food coloring to make orange filling(may
need to add more to reach desired shade of orange) Stir in choc. chips. Place
1 tsp of filling on top of batter and top this with remaining batter. Bake
according to directions for cupcakes. Frost with orange or chocolate frosting
and decorate with Halloween candies or sprinkles. Should make about 24
cupcakes.
