# Expert Advice:

01 -
  • Three minutes from craving to eating means you'll actually make it instead of scrolling through dessert photos online.
  • It tastes like you spent an hour baking, but you know the truth and that feels like cheating in the best way.
  • The mug becomes your bowl, so there's barely any cleanup, which is the real victory at night.
02 -
  • Don't open the microwave to peek halfway through—the sudden loss of heat can cause the cake to collapse, so resist the urge even though it's tempting.
  • The difference between fluffy and rubbery is about ten seconds, so if you're new to your microwave, start checking at 60 seconds by looking for the cake to rise; times vary wildly between machines.
03 -
  • Use a 12-ounce mug or larger so the batter has room to rise without overflowing; a coffee mug is too small and a cereal bowl is too big.
  • If your microwave is particularly powerful, start at 50 seconds and check; if it's older, you might need the full 75 seconds, and that five-second difference prevents the difference between perfect and overcooked.
