03 - Stir in the flour, sugar, baking powder, and salt until just combined without overmixing.

# Helpful Hints:

01 -
  • It takes less time than scrolling through dessert photos online and actually satisfies the craving.
  • You get all the comfort of homemade cake without turning on the oven or dirtying a single bowl.
  • The peanut butter flavor is bold and rich, not an afterthought.
02 -
  • Use a mug that holds at least 12 ounces or the batter will overflow and make a mess in your microwave.
  • Every microwave is different, so start with 60 seconds and add time in 10 second bursts if needed.
  • The cake will look slightly underdone in the center when you pull it out, but it finishes cooking as it cools.
03 -
  • Whisk the wet ingredients really well so the egg is fully incorporated and the cake rises evenly.
  • If you want a fudgier center, pull it out at exactly 60 seconds and let residual heat finish the job.
  • Make two at once if you're sharing, because one mug is never enough.
