1 Minute Coffee Mug Cake in Microwave
This one-minute coffee mug cake is soft, moist, and rich with real coffee flavor. Made with an egg, milk, oil, flour, and instant coffee in one mug, it bakes up fluffy in 60 seconds. A warm, satisfying little cake that comes together faster than making a proper cup of coffee, and perfect for an afternoon pick-me-up.
