"Slime" Filled Cupcakes

I always try to make some sort of yummy treat for my co-workers around holidays.  With Halloween less than a week away, I thought it was a good time to try out a new recipe.  I made these last night, because I will not be in the office on Halloween.  These cupcakes are a combo of two different recipes and amazingly they turned out delicious.  If you like chocolate, this is a cupcake for you.  The chocolate frosting might be one of the best frosting's I have ever tasted.  I stood in the kitchen licking the beaters clean, it was so good!  Here is the recipe:

Cupcake:
2 2/3 c. all-purpose flour
2 c. sugar
3/4 c. cocoa
2 tsp. baking powder
1 tsp. baking soda
1 tsp. salt
2 c. water
3/4 c. vegetable oil
4 tsp. vanilla extract

Line 30 muffin cups with paper liners and preheat oven to 350 degrees.
Sift together flour, sugar, cocoa, baking powder, baking soda and salt in medium bowl.  Add water, oil and vanilla; stir until batter is blended.  (Batter may be thin.)  Spoon into prepared cups, filling 2/3 full.  Bake for 15 minutes or until toothpick comes out clean.  Transfer cupcakes to wire racks after 5 minutes and cool completely.

Filling:
1/4 c. shortening
3 Tbsp. butter, softened
2 c. confectioners' sugar
2 Tbsp. milk
8 drops green food coloring, optional

Cream the shortening, butter, confectioners' sugar, milk and food coloring until light and fluffy.  Using a pastry bag with a small round tip, add the filling to the bag.  Push the tip through the bottoms of paper liners to fill cupcakes (the top of the cupcakes will begin to expand when they are full).

Frosting:
1/2 c. butter, softened
4 oz. cream cheese, softened
2 c. confectioners' sugar
1/4 c. baking cocoa
2 Tbsp. milk
Combine all ingredients together and frost cupcakes.

Glaze:
1/2 c. confectioners' sugar
1 Tbsp. milk
6 drops green food coloring
Combine glaze ingredients and drizzle over frosting.

This cupcakes are delicious but they were a little time consuming.  Make sure you have enough time when attempting these.  I would also suggest filling the cupcakes from the top.  This way you don't have to worry about breaking through the paper and the hole on the top will be covered with the frosting later.  Enjoy and Happy Halloween!
