One of the best flavor marriages with chocolate is coffee or espresso. They bring out the best in each other! These cookies are a perfect example. Rich, fudgy, and perfectly crackly on top, these are great occasion-worthy cookies. The secret is to find chocolate-covered espresso or coffee beans. Blitz them in the food processor until they’re broken up, and once folded into the cookie dough, it gives a great espresso flavor throughout along with a crunchy texture in the cookies.
