  • 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.

What makes homemade peanut brittle sticky? ›

It uses the most basic of ingredients (sugar, corn syrup, and peanuts). What's important to know is that the corn syrup controls the grain of the brittle so adding too little and you have a grainy textured brittle, while adding too much will result in a stringy and sticky brittle.

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. A thermometer is an accessible and inexpensive way to monitor temperature and ensure properly cooked brittle. Make sure your baking soda is fresh and active.

Why is my peanut brittle not airy? ›

What is the best pan for making peanut brittle? ›

Heavy 6 quart Dutch Oven pot. Mine is an old 1970's Club Aluminum. It's perfect! You need a heavy THICK pot so it won't scorch.

Can you pour hot peanut brittle onto parchment paper? ›

You can spread the hot brittle mixture on parchment paper or a silpat liner, but I find the silpat liner a bit safer as it doesn't move around on the sheet pan like parchment has a tendency to. I've been able to keep brittle crisp for up to two months.

Can I freeze homemade peanut brittle? ›

How long is homemade peanut brittle good for? ›

Baking soda helps to aerate brittle — it literally makes the molten candy bubble in the pot — to create a brittle with an airy, almost honeycomblike texture that crunches easily when eaten.

What does baking soda do in candy making? ›

The soda reacts with the acid to make bubbles, and the syrup foams. When the cooked syrup is poured out and begins to harden, many of the tiny bubbles are trapped before they can escape (another reason the baking soda is added at the end).
