- Don’t over‑microwave — aim for “set but still a little moist” in the center.
- Toppings like mini marshmallows, whipped cream, or chocolate syrup take this simple treat to next‑level.
Storage Directions
- Storing: These mug cakes are best eaten right away — they don’t keep well when stored.
- Reheating: If you happen to have leftovers (rare!), you can briefly microwave for ~15‑20 seconds to warm.
- Make ahead: Not recommended for full prep ahead — batter tends to change; better to mix right before microwaving.
