Madeleines au Chocolat

These are the madeleine version of pain au chocolat—a classic puff pastry filled with chunks of dark chocolate. Even if you don’t have the time or patience to make a chocolate-filled croissant at home, these madeleines are a cinch to create and every bit as tasty as what you’d get in a French bakery. The rich taste of the chocolate is a delicious contrast to the vanilla-y cakelet. Serve these warm, when the chocolate in the middle is still gooey.
