Microwave timing guide
| Microwave wattage | Start time | Add if needed |
|---|---|---|
| 700–800W | 85 sec | 5–10 sec |
| 900–1000W | 75 sec | 5 sec |

Stop when the top looks just set. Overcooking makes mug cake rubbery.
Easy variations

Troubleshooting
- Too dry: reduce cook time by 5–10 seconds or add 1 tbsp milk.
- Too dense: make sure baking powder is fresh.
- Bitter taste: reduce matcha to 3/4 tsp or increase sweetener slightly.
