  • 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

    • Jaclyn

      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.

FAQs

Why didn't my homemade peanut brittle get hard? ›

The main reason why peanut brittle doesn't get hard and have the crunch we expect is because the sugar was not cooked long enough. The sugar needs to be cooked to what is called the hard crack stage, 300ºF.

Why put baking soda in peanut brittle? ›

Baking soda is also very important at this stage since it reacts to the heat, creating carbon dioxide that aerates the caramel, enabling it to snap when someone bites into it rather than requiring them to gnaw at it until it breaks or pulls apart.

How do you keep peanut brittle crispy? ›

Should you refrigerate peanut brittle? Store the brittle in an airtight container at room temperature for up to 1 month to maintain the crisp. Moisture in the refrigerator would soften the brittle.

Why is my peanut brittle not fluffy? ›

It is important to coat cookie sheets with butter and put in the freezer to get them really cold before you need to pour the brittle. After you pour the candy you should put the pans in the fridge or outside if it is cold, so the brittle will set up quickly and stay fluffy.

What makes peanut brittle too hard? ›

Why is it too hard? Using baking soda usually prevents peanut brittle from being too, well, brittle. However, if you cook the candy past the set temperature or overwork the candy once you spread it out onto the cookie sheet, that can cause it to become very hard and difficult to bite through.

Can you overcook peanut brittle? ›

If you overcook the brittle, it could be bitter or burnt. If you undercook it, the brittle won't properly set and the end result will be sticky.

Can you use parchment paper when making peanut brittle? ›

You will want the cookie sheet to be non-stick. Use parchment paper, a silicone baking sheet or a greased cookie sheet. Spread the peanut brittle as thin as you can. Immediately add your sea salt.

Should homemade peanut brittle be refrigerated? ›

To store: Store peanut brittle (once it's completely cooled) in an airtight container at room temperature. Do not refrigerate as the moisture from the fridge will cause the brittle to soften. Store for 6-8 weeks. To freeze: Peanut brittle can be frozen and stored up to 3 months.

Why do you put water in peanut brittle? ›

The water is there in the first place to help prevent sugar crystals. Steam from the boiling water washes down the sides of the covered pot as the sugar cooks and takes with it, down into the boiling sugar, any crystals that form or are thrown onto the sides of the pot.

Can I use foil instead of parchment paper for peanut brittle? ›

You will absolutely ruin your brittle if you pour it directly on the baking sheet or use foil, plastic wrap, or wax paper to line the pan. You can only use parchment paper or a silpat.

Can I use aluminum foil instead of parchment paper for peanut brittle? ›

Recommended Equipment for making homemade Peanut Brittle:

aluminum foil or parchment paper. vegetable cooking spray.

What makes brittle hard? ›

What Makes it Brittle? The sugar will be cooked to 300ºF (149ºC)—hard crack stage; which when set up would be hard like a lollipop. But peanut brittle is delicate and you can easily bite into it—how? The secret is in the baking soda.

How long does it take for brittle to harden? ›

Don't try to spread the candy once it's on the baking sheet as it starts hardening almost immediately and spreading it doesn't work well. Let the peanut brittle cool for 30 minutes, then break it into pieces. Store it in an airtight container at room temperature for up to two months.

Why did my peanut butter fudge not get hard? ›

The main reason is that your Fudge has not reached the optimum temperature. If your mixture only reaches 110 or 112 degrees Celsius it will always be soft. That's why we recommend investing in a sugar thermometer. Another reason your Fudge is not setting is that the ratio of liquid to sugar is too high.
