  • Cook times may vary slightly depending on microwave wattage. Watch for a golden brown color near the end.
  • Reviewers have mentioned trouble with this recipe in recent years. I believe this is due to microwaves being made with higher wattages.
  • Newer higher wattage microwave should have 30 seconds cut from each cook time.
  • Note that the less you spread the lighter the brittle will be, or more air bubbles it will have, so if you prefer it like so then do as little spreading as possible. If you prefer it flatter then spread it out thin.

    This was by far the best peanut brittle I have ever had in my life!

  • Patricia

    When I stayed with the recipe for your peanut butter I found that it was very close to burning.Can you tell me what the the wattage should be , I have a new microwave and have no idea what temperature I should cook it at ,my microwave is 1200 watts and not sure if I need to cook it at 5-6-7 power to get results.Would love to hear from you ,have made peanut brittle before with great results but that was with an old micro. Thank you so much for your time, Patricia

  • Liz

    This is a great recipe but I recommend adding 1/4 cup water to the sugar and corn syrup.

  • Kimberly S Boxer

    So easy and great; I find myself making a batch every week or two. Have you ever tried it with Brown Sugar or Honey?

  • Carolyn parker

    Can this recipie be doubled

      Unfortunately no I don’t recommend doubling.

  • Marilyn

    Can you please tell me what containers are safe to make this recipe in because it’s obviously a high temp recipe. I’d had a hard plastic container that said it’s microwave safe but it started to melt. Glass can explode so any advice will be greatly appreciated.

      This is a difficult question and that’s why I’ve redirected to All Recipes where I got the recipe from because I don’t know the safety on this. I believe pyrex is microwave safe to high temperatures but I would refer to their website or help center. Some glass bowls these days aren’t made as well so I definitely recommend checking with the manufacturer for safety precautions.

      • Jo Ann Campbell

        I just researched that very same thing. I have a Pyrex bowl from the 70’s and about to try it. The information I found said the bowl can withstand 450 degrees.

    • Kimberly S Boxer

      I got a anchor hocking bowl with a handle from Wayfair since I didn’t have a bowl big or sturdy enough.
