Tips
Use a mug taller than it is wide to prevent overflow. The cake rises significantly during cooking.
Don't overmix the batter. Lumps are fine and actually create a tender crumb structure.
Stevia can have a slight aftertaste; vanilla extract helps mask this and adds warm flavor depth.
Good to Know
Eat immediately for best texture. If storing, cover mug with plastic wrap and refrigerate up to two days. Texture deteriorates as it cools.
Mix dry ingredients in a small bowl up to one day ahead. Combine wet ingredients and dry ingredients just before microwaving for optimal rise.
Serve warm, optionally topped with whipped cream, fresh berries, or a drizzle of sugar-free syrup. Pairs well with coffee or tea.
Common Mistakes
Overfill mug to avoid cake overflow.
Don't skip the salt; it balances stevia's aftertaste.
Don't use a non-microwave-safe mug to avoid hazardous metals or damage.

Can I use a regular mug instead of microwave-safe?
No. Non-microwave-safe mugs may contain metals or glazes that heat dangerously. Always verify your mug's microwave rating before use.
What if my cake doesn't rise?
Baking powder may be expired; check the date. Ensure you mixed wet and dry ingredients thoroughly. Microwave wattage varies; older microwaves may need extra 10-15 seconds.
How long does the mug cake keep?
Best eaten immediately while warm. Refrigerated leftovers last two days but become dense and dry. Not recommended for freezing due to poor texture recovery.
