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.

Ingredients

  • 1 ripe banana – The riper, the better! It adds natural sweetness and moisture.
  • 1 egg – This helps bind the ingredients together; you can use a flax egg for a vegan option.
  • 3 tablespoons all-purpose flour – For a gluten-free version, substitute with almond or coconut flour.
  • 2 tablespoons sugar – Adjust to your taste; honey or maple syrup works too.
  • 1/4 teaspoon baking powder – Ensures a fluffy texture.
  • 1/2 teaspoon vanilla extract – A must for flavor depth.
  • A pinch of cinnamon – For that cozy, warm flavor.
