Caffeine Infusion Muffins

It isn’t easy to return to a proper routine after months of lazing about during the summer. These muffins might help ease the transition from vacation mode to work mode: you can get your caffeine fix and begin your day on a slightly sweeter note. These muffins are ridiculously easy to throw together and make for a much-appreciated lunchbox treat. If you prefer a caffeine-free version, you can substitute decaf alternatives.
