After experimenting with so many mug cakes, I kept coming back to one thing: I loved how each new recipe felt like a small, delicious discovery.
One day, I found myself with an overripe banana—too soft to eat on its own but perfect for baking. Rather than making a full loaf of banana bread, I decided to test a Banana Mug Cake.

Now, whenever I have a ripe banana on hand, I know it’s the perfect opportunity to make this quick and comforting treat.
