I'm not sure if you can use the name Cream Puff and Profiteroles alternately, but growing up, I've always called them Cream Puffs. I am under the impression that Cream Puffs are dusted with icing sugar while Profiteroles are glazed with chocolate ganache. Someone out there, please correct me! But what's in a name if they both taste so soooo good, right?? They are, basically the same thing after all - made from the same choux pastry.
The recipe was taken from Joy of Baking, the pastry cream recipe is Martha's (refer here) while for the chocolate ganache, I mixed some whipping cream and couverture bittersweet chocolate.
