# Expert Advice:

01 -
  • It satisfies a dessert craving faster than you can talk yourself out of it.
  • Only one mug to wash, which matters more than it should at 10 p.m.
  • The peanut butter flavor is deep and comforting without feeling too sweet.
  • You can tweak it every time based on what you have or what sounds good.
02 -
  • Do not microwave past 75 seconds or the cake will turn rubbery and dry instead of fluffy.
  • Use a mug that holds at least 12 ounces because the batter rises fast and can overflow in a small cup.
  • Stir just until combined, lumps are fine, overworking the batter kills the tenderness.
03 -
  • Lightly grease the inside of the mug with butter or oil so the cake releases easily if you want to flip it onto a plate.
  • Whisk the egg mixture really well to incorporate air, it makes the final texture lighter and fluffier.
  • Let the mug sit on the counter for 30 seconds after microwaving, the residual heat finishes cooking the center gently.
