I made this Vegan Coffee Mug Cake for my coworker’s going-away party last month. The coffee gave it a bold flavor fast, and my book club asked for it.
Perfect for those days when you want a small dessert without the hassle of baking an entire cake, this mug cake is both vegan and delicious, offering a delightful blend of coffee flavor and cake-like texture.
