Macarons are delicate. Macaron bakers running on four hours of sleep are slightly less so. The Tired Macaron Bakers Club coffee mug is for anyone who has stayed up too late piping shells, matching pairs and filling one more box before tomorrow’s pickup. Keep the caffeine close through macaronage, baking, filling and packaging. A funny gift for macaron bakers, cottage bakers and bakery owners who are exhausted, flour-covered and still somehow planning another batch.
