# Expert Suggestions:

01 -
  • It takes less time than digging through the freezer for forgotten ice cream and tastes a hundred times better.
  • You only dirty one mug and one fork, which means no guilt about skipping the dishes until morning.
  • The texture hits that perfect spot between gooey lava cake and fudgy brownie without any guesswork.
  • You can make it exactly as sweet or as chocolatey as you want without worrying about leftovers tempting you all week.
02 -
  • Every microwave is different, so start with 50 seconds and add time in 10-second bursts if needed—overcooking turns it into a rubbery puck.
  • Use a mug that's bigger than you think you need because the batter rises dramatically and will overflow a small cup, creating a sad, crusty mess.
  • Don't skip the pinch of salt—it sounds unnecessary, but without it the brownie tastes flat and too sweet.
03 -
  • Use room temperature milk so the batter mixes more smoothly and microwaves more evenly.
  • If you want a molten center, press a few chocolate chips into the middle of the batter before microwaving.
  • Clean the mug immediately after eating—dried brownie batter is stubborn, but a quick rinse while it's still warm makes it disappear.
