# Expert Advice:

01 -
  • Ready faster than ordering takeout, and you only dirty one mug.
  • Rich peanut butter flavor that tastes like you spent real time on it.
  • No mixer, no oven, no guilt about making a whole cake just for yourself.
02 -
  • Do not microwave longer than 75 seconds or it turns rubbery and dry.
  • Use a mug that holds at least 12 ounces or the batter will overflow.
  • Natural peanut butter works but may need an extra second or two in the microwave.
03 -
  • Whisk the egg really well with the wet ingredients to avoid rubbery patches.
  • Stop the microwave a few seconds early and let residual heat finish the job.
  • Use a mug with straight sides so the cake rises evenly instead of spilling over.
