  • 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.

Why did my peanut brittle not turn brown? ›

If your peanut brittle reached 311°F but is a pale milky color, it's likely the candy cooked too quickly. It reached the correct temperature but didn't cook long enough to undergo sufficient Maillard reactions and develop the characteristic brown color and rich, roasted flavor. Next time, cook at a lower temperature.

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 is my peanut brittle so thick? ›

Not spreading the mixture thinly enough: If the peanut brittle is too thick (usually because you used too small of a pan), it may not cool and harden properly.

Buttering the inside of the cooking pan will prevent sugar crystals from sticking to the sides while the corn syrup, water, sugar and butter cook to 275 degrees.

When candy cools slowly on a stone slab, more crystals have a chance to form. With a higher number of micro-crystals, the sugar has more sites on which to crystallize, and so crystallization ultimately happens faster.

Why is my peanut brittle not airy? ›

Working quickly, pour into prepared 10×15 pan. To keep the brittle light and airy, do not spread or flatten the mixture. Instead, let it flow freely. Place in a cool area and leave until completely cooled, about 2-3 hours.

What is the interfering agent in peanut brittle? ›

Examples of interfering agents include corn syrup and cream of tartar. A key step in making brittle is heating the syrup to the proper temperature.

What does baking soda do when making candy? ›

When the baking soda combines with the boiled sugar, it creates Carbon Dioxide that form lots of bubbles and puff the candy up. Once it hardens, the bubbles get trapped inside and create a texture that looks just like a sponge or piece of foam. It's crunchy and sweet, with an almost molasses-like flavor.

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.
