How to Make Banana Bread Mug Cake
1. Prep the Mug
Choose a large microwave-safe mug or ramekin.
Lightly grease the inside with butter or oil to prevent sticking.
2. Mash the Banana
Add the banana to the mug and mash thoroughly until smooth.
3. Add the Wet Ingredients
Stir in:
- egg
- milk
- vanilla extract
Mix until fully combined.
4. Add the Dry Ingredients
Add:
- flour
- sugar
- baking powder
- cinnamon
- salt
Stir until a smooth batter forms.
Do not overmix — a few small lumps are fine.
At this stage, fold in chocolate chips, nuts, or other add-ins if desired.
5. Microwave
Microwave on high for 1 minute, then check doneness.
If still wet in the center, cook in 10–15 second intervals until set.
Avoid overcooking — it should be soft and moist.
6. Finish and Serve
Top with banana slices and drizzle lightly with honey or maple syrup.
Enjoy warm, straight from the mug.

Tips for Best Results
- Use a ripe banana for maximum sweetness
- Mug should be at least 12 ounces to avoid overflow
- Cook in short bursts at the end to avoid drying out
- Let it rest 1 minute before eating — it continues cooking slightly
- For a caramelized top, microwave until just golden, then torch lightly (optional)
Storage Instructions
Mug cakes are best eaten immediately.
However, you can refrigerate leftovers for up to 1 day and reheat for 10–15 seconds.
