Notes

  • Use roasted, salted peanuts.  If you prefer small bits of peanuts, chop them up before adding to the brittle.
  • The key to this recipe is to work quickly because the microwave peanut brittle hardens.
  • Be sure to have a towel or pot holder handy for moving the bowl around. It is hot hot hot, and you don't want to get burnt.
  • Boiling sugar is super hot as well. Resist the urge to touch the peanut brittle with your hands until it has hardened and cooled. Keep little hands away too.
  • Spray all surfaces with nonstick cooking spray to help with clean up.  This includes the microwave-safe bowl, spatula, liquid measuring cup (for Karo), and the sheet pan.
