# Expert Advice:

01 -
  • It takes less time than scrolling through a dessert menu and tastes better than anything you could order.
  • You probably already have every ingredient sitting in your pantry right now.
  • There are no bowls to wash, no oven to preheat, and no leftover cake tempting you from the counter.
  • The peanut butter flavor is rich and satisfying without being too heavy or overly sweet.
02 -
  • Every microwave is different, so start with 60 seconds and add time in 10-second bursts if needed. I learned this after nuking my first attempt into a rubber disk.
  • Use a mug that holds at least 12 ounces or the batter will overflow and make a mess. Trust me, I've cleaned melted cake off the microwave turntable more than once.
  • Don't skip the resting time after microwaving. The cake continues to set as it cools, and cutting into it too soon leaves you with a gooey center that hasn't quite come together.
03 -
  • For an extra fudgy center, pull the mug out when the edges are set but the middle still looks slightly shiny. It'll firm up as it cools.
  • Natural peanut butter works, but stir it really well first. The oil separation can make the batter greasy if it's not mixed properly.
  • If you want a sweeter cake, add a tablespoon of brown sugar instead of all granulated. It gives a deeper, almost caramel-like flavor.
