This simple recipe, modestly entitled “Chocolate Cupcakes” from the 1974 book “Maida Heatter’s Book of Great Desserts,” produces cakes with a rich, moist crumb that relies on cocoa powder for a deep chocolatey flavor. But it’s the topping of semi-sweet chocolate ganache that separates these cupcakes from the crowd.
03Scoop the batter into the prepared pans filling each about two-thirds full (don’t bother to smooth the tops--the batter will level itself as it cooks). Bake the cupcakes for about 25 minutes, or until the tops are puffed and spring back when lightly pressed. Be careful not to overbake the cakes, but know that if you take them out too early they may sink a bit. Cool the cakes in the muffin tins for about 5 minutes and then remove them to a rack and let cool completely.
04To make the ganache, put all the ingredients in a small, deep saucepan over medium-low heat. Cook, whisking occasionally to combine, until the chocolate and butter are nearly melted. Take the pan off the heat and whisk continuously until all the chocolate is melted; the ganache should be shiny and without any lumps.
05When the ganache is about room temperature, use a butter knife to spread it evenly on top of the cakes; sprinkle with nonpareil if you like. The cakes can be made a day in advance and refrigerated (they actually get better) or frozen in an airtight container.
