Chocolate-filled Cream Puffs

This dessert was to celebrate Ben taking his final final. YAHOO! Thesis is still to go, but the end of classes feels pretty good.
I can't believe how well these puffs turned out. They were puffy! And mostly hollow on the inside! And held their shape! Also, I could've eaten the filling alone, so I want to figure out another use for it. Thank you, Better Homes and Gardens Baking book.
