Mocha-Filled Cream Puffs

I made two desserts for the challenge, but this one I decided should not be considered...

I ate this with two friends. We decided, and tested to prove later, that the recipe turns out better with a few squirts of Chocolate sauce and about 1 cup of whipped cream mixed into the cream filling. You could probably do away with the coffee as well. of course, then, it would just be cream puffs, not mocha cream puffs. But here is the original recipe.

Chocolate-Filled Cream Puffs
Ingredients:
CHOCOLATE CREAM FILLING(recipe follows)
1 cup water
1/2 cup (1 stick) butter or margarine
1/4 teaspoon salt
1 cup all-purpose flour
4 eggs
Directions:

2. Heat oven to 400°F. Heat water, butter and salt to rolling boil in medium saucepan. Add flour all at once; stir vigorously over low heat about 1 minute or until mixture leaves side of pan and forms a ball. Remove from heat; add eggs, one at a time, beating well after each addition until smooth and velvety. Drop batter by spoonfuls into 12 balls (about 1/4 cup) onto ungreased cookie sheet.

3. Bake 35 to 40 minutes or until puffed and golden brown. While puff is warm, horizontally slice off small portion of top; reserve tops. Remove any soft pieces of dough from inside puff; cool completely on wire rack. Fill puffs with CHOCOLATE CREAM FILLING. Replace tops.
