Step 1
Preheat the oven to 400 degrees F (200 degrees C). Grease a baking sheet lightly with some shortening. Put beaters into the freezer to chill.
Step 2
Combine water and shortening in a saucepan and bring to a rolling boil over medium-high heat. Add flour cocoa powder sugar and salt all at once and reduce heat to low. Stir mixture vigorously until it leaves the sides of the pan and forms a ball about 1 minute. Remove from heat and cool for 5 minutes.
Step 3
Beat in eggs one at a time with chilled beaters beating vigorously after each addition until batter is smooth and glossy. Drop dough into 6 mounds on the prepared baking sheet.
Step 4
Bake in the preheated oven until puffed and dry 25 to 30 minutes.
Step 5
Remove from the oven and pierce the side of each puff with a knife to allow steam to escape. Transfer onto a wire rack to cool completely abut 20 minutes.
Step 6
Meanwhile combine sugar cocoa powder and whipping cream in a bowl for the filling. Beat with an electric mixer until stiff peaks form. Refrigerate until needed.
Step 7
Cut cooled puffs in half horizontally. Fill with cocoa whipped cream.
Step 8
For the glaze pour whipping cream into a small pot and heat until hot. Remove from heat and stir in chocolate chips until melted. Allow to cool slightly. Drizzle chocolate glaze over the cream puffs and refrigerate until serving.
