- 2
Stir with fork until mixed.
- 3
Add milk and oil, stirring until combined.
- 4
Fold in chocolate chips and crushed peppermint candies.
- 5
Check batter level - if over halfway full, use a damp paper towel to wipe excess from mug sides to prevent overflow.
- 6
Microwave for 90 seconds.
- 7
Let stand 1-2 minutes before serving.
Tips
Fill mug only halfway with batter to prevent microwave overflow; wipe sides with damp paper towel if needed before cooking.
Crush peppermint candies just before adding for maximum flavor and freshness.
Let cake rest 1-2 minutes post-microwave to set slightly; overcooking creates tough, dry texture.
Good to Know
Best enjoyed fresh. Leftover cake (if any) stores in mug covered at room temperature up to 8 hours, though texture deteriorates quickly.
Mix dry ingredients in mug ahead of time; add wet ingredients and cook when ready.
Serve warm from mug alone or topped with vanilla ice cream, whipped cream, or fresh berries.
Common Mistakes
Overfill mug to avoid batter overflow in microwave - leave 1-2 inches headspace
Skip standing time to avoid underbaked center - let rest 1-2 minutes for set crumb
Overcook past 90 seconds to avoid tough, dry cake - check at 90 and add 15-second intervals if needed

FAQ
Can I make this without cocoa powder?
Yes, replace cocoa with additional 2 TBS flour and 1 TBS melted chocolate for chocolate mug cake, or omit both for vanilla base cake. Texture will be lighter and less fudgy.
What if my microwave is very powerful - should I reduce cook time?
Start at 75 seconds and check for doneness. Microwave wattage varies widely. Cake should be set on edges but slightly underbaked in center for fudgy texture.
How long can I keep the batter before microwaving?
Use within 15-20 minutes of mixing wet and dry ingredients. Baking powder activates upon contact with liquid, so longer wait times reduce rise and fluffiness.
