Espresso Chip Madeleines

When cocoa and coffee beans converge, mocha is born—and as a mocha latte devotee, I felt compelled to create a dark chocolate madeleine with a strong espresso flavor. Increase the espresso powder or add a tablespoon or two of freshly brewed espresso for an even richer coffee flavor. Just be careful not to eat these madeleines too late in the evening (unless you’re trying to pull an all-nighter) because they pack a hefty dose of caffeine!
