Yes! You can cook two mug cakes at one time. I typically try to leave about an inch of space between the individual mugs inside the air fryer.
What should I look for in a quality air fryer
You want your air fryer to have a good amount of wattage (800-1600 watts is best). I also recommend getting an air fryer that is big enough to cook for your family size. I always make sure that the air fryer that I am purchasing can heat up to 400 degrees Fahrenheit.
What kind of mug do I need to make mug cake
The best size mug for this recipe is a 12-ounce glass or ceramic mug. These mugs will usually have a flat bottom and be about three inches high.
The width of the mouth opening should not exceed two inches to ensure that there's enough cake batter in the middle when it pops out after cooking! If you don't have an a mug on hand a small 12 ounce ramekin would work as well.
Can I make mug cake ahead
Yes! You can make this in advance and store it for up to a week. i find that if I make my mug cake ahead that reheating in the air fryer makes it taste fresh again.

How long does this cake last
Mug cakes will typically stay fresh if stored properly at room temperature where they'll last up to seven days.
How can I reheat a mug cake
Many people will use the microwave, but I prefer to reheat in my air fryer. To reheat your mug cake in the microwave reheat 30 seconds at a time on high until your mug cake is completely warm through the center.
How to reheat a mug cake in an air fryer
Preheat your air fryer to 350 degrees Fahrenheit. Add the mug cake and cook for about a minute. Test for warmth in the center of your mug cake. If your mug cake is not warm return to your air fryer for another minute.
Can I freeze this cake
Yes! The best way to freeze a mug cake is by wrapping it in plastic wrap. Place the wrapped mug cake into an airtight container and store in the freezer for up to three months.
