How to Make Peanut Brittle In the Microwave

First, you need a 1100 watt microwave to have success with this recipe. If your microwave is not 1100 watts I can’t guarantee the results. So if your microwave is not 1100 watts go out and buy a new microwave. It will be worth it. Just kidding. Sort of. 🙂

In a 1.5 quart baking dish combine raw peanuts, sugar and light corn syrup. So many recipes out there say to use regular peanuts. Don’t do it. You need raw peanuts that will cook naturally as you make this recipe. You can find raw peanuts with skins in the produce section of your grocery store. They’re not with all the other peanuts. Why? Why!

You can store in an airtight container on the counter for up to 1 week or until you find it starts to taste stale.

    I made your brittle. After a couple of hours cooling It was still very soft so I put the tray in the refrigerator for several more hours. Finally about 4 hours later it was mostly hard enough to break up. Put it in a sealed container and in the morning I had one solid piece of brittle that was soft again. I’m at a loss, can i fix this??

      Hi Catherine, it sounds like your peanut brittle didn’t get to a high enough temperature. It would have become hard as it cools. Unfortunately, the batch you have cannot be fixed. Two things probably happened, either you accidentally missed a step in the timing so the peanut brittle didn’t get hot enough. Or if directions were followed exactly, then your microwave didn’t work correctly. This recipe is based on an 1100 watt microwave so any other wattage would have different results. I’m sorry I can’t be more help. I would try it again. I just made two batches of peanut brittle this week and had excellent results, so I would give it another go! Let me know how it goes and if you have any other questions.

    I had a microwave peanut brittle recipe from years ago that I used all the time and the brittle came out perfect. Unfortunately, I lost it. The problem with these microwave brittle recipes is that most of them don’t list the recipe’s microwave wattage and I just overcooked a batch a few minutes ago and had to throw it out. Fortunately, I didn’t give up my search and happened to find this recipe for 1100 watt microwaves. Just want to let you know that with this recipe my brittle turned out perfect and delicious. Thank you so much!

    i love been making the peanut brittle recipe since the ‘80s – was in the recipe book that came with my microwave! to ensure easy spreading of the brittle, i place my baking sheets in a warm oven. and, if making more than one batch, clean out the left over brittle in your bowl by using very hot water to melt it away. same for the spoon. dry the bowl and spoon and you are ready to go on the next batch.

    **peanut brittle does not set up well if making on a humid day. best to make when cold days are here.

      We’ve had lots of cold days! Just made this recipe again yesterday and love how easy it is. Great idea to warm the baking sheets. My kitchen can be cold and I did find it harder to spread. Thanks for the tips!

      I got my recipe when I had a 725 watt microwave then I got a new on and it was an 1100 watt burned every batch. I can’t wait to try this one. I use two Correll bowls when one batch is done I use HOT water to clean out the other so I can keep them going. They make great Christmas gifts and they always ask for more. 😂
