Ingredients
To create this scrumptious mug cake, you will need:
Dry Ingredients
- 1 ripe banana, mashed (the riper, the better!)
- 3 tablespoons all-purpose flour
- 2 tablespoons granulated sugar
- 1/8 teaspoon baking powder
- 1/8 teaspoon baking soda
- Pinch of salt

How to Make Banana Bread Mug Cake (Step-by-Step)
This recipe is super simple and can be made in just a few easy steps!
Step 1: Mash the Banana
In a microwave-safe mug, mash a ripe banana with a fork until it’s completely smooth. The natural sweetness of the banana intensifies as it breaks down.
Step 2: Combine the Ingredients
Add the flour, sugar, baking powder, baking soda, and salt directly to the mug. Mix until just combined—this is where you’ll experience the pleasing sight of the banana and flour amalgamating into a thick batter.
Step 3: Add Wet Ingredients
Pour in the milk, vegetable oil, and vanilla extract. Whisk with a small fork until the mixture is glossy and smooth, making sure to scrape down the sides of the mug to incorporate all the dry ingredients.
Step 4: Microwave
Microwave the mug on high for about 1 minute and 30 seconds. Keep an eye on it; the cake should rise nicely but not overflow. The center should have a slight jiggle when you take it out, indicating the perfect moist texture.
Step 5: Cool and Enjoy
Wait a minute for the mug to cool slightly before diving in. I often top my banana bread mug cake with a dollop of whipped cream or a drizzle of nut butter for an extra touch of indulgence—a true holiday treat indeed!

Common Mistakes to Avoid
- Using unripe bananas, which can result in a less sweet and flavorful cake.
- Not using a microwave-safe mug; avoid metal or plastic mugs not labeled microwave-safe.
- Overcooking the cake, which may lead to a rubbery texture—keep an eye on it.
Tips and Tricks for Success
- Use a ripe banana: Look for bananas with dark spots for optimal sweetness and flavor.
- Don’t overmix: Stir until just combined, leaving a few lumps for the best texture.
- Adjust microwave times: If your cake isn’t done after 1 minute and 30 seconds, increase in 10-second increments.
Variations
- Add a sprinkle of cinnamon for warmth.
- Incorporate chopped walnuts for crunch.
- Substitute whole milk with almond milk for a dairy-free option.
- Use melted coconut oil instead of vegetable oil for a tropical hint.
How to Serve
- Top with a dollop of whipped cream for extra indulgence.
- Drizzle with nut butter for added richness.
- Pair with a scoop of vanilla ice cream for a delightful treat.
- Serve warm right out of the microwave for the best experience.

Make Ahead and Storage
- Make Ahead: This mug cake is best made fresh, but the ingredients can be pre-measured for quick assembly.
- Storage: Cover the mug loosely with plastic wrap if there are leftovers; however, it is best enjoyed immediately.
- Reheating: If reheating, microwave for 10-15 seconds until warm.
- Freezing: This mug cake is not suitable for freezing, as it is designed for single-serving enjoyment.
