FREQUENTLY ASKED QUESTIONS:

Is this recipe easy?

I would say this recipe is for someone who already has familiarity with using a candy thermometer. This is not for the novice baker. If you are okay attempting this even though you’ve never made it before or never used a candy thermometer, please understand it may take a couple of tries to get it right and you must be patient and never leave or turn away from your pot. Some folks have commented they got it perfect the first try so it is possible. Please see all my FAQ questions here to help you get the best possible outcome.

How do I know if the peanut brittle is ready?

You MUST use a candy thermometer if you are not familiar with candy making. It’s the only way to be sure and not ruin or waste all your ingredients. Very experienced candy makers can often look at it and know when it is ready but most of us can’t. It is the only sure-fire way to know if the mixture is ready and at the “hard crack” stage (300F degrees.) If you are not going to use a candy thermometer, do not use this recipe.

How come my peanut brittle did not get hard?

It could be because of a few reasons:

1. Not cooking the sugar mixture long enough: Peanut brittle relies on the sugar mixture reaching the hard crack stage, which is about 300°F (150°C) on a candy thermometer. If the mixture is not cooked long enough, it will not harden properly.

2. Using too low of a heat: It’s important to cook the sugar mixture over medium heat. If the heat is too low, the mixture will not reach the hard crack stage and will not harden properly.

3. 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. Be sure to spread the mixture as thinly as possible in the pan.

4. Humidity: Humidity can affect the hardening process of the peanut brittle. If the weather is humid, it may take longer for the peanut brittle to cool and harden, or it may not harden properly at all.

If any of these factors apply to your peanut brittle, you can try to salvage it by reheating the mixture and cooking it longer to reach the hard crack stage. However, if the mixture has already cooled and slightly hardened and is still not brittle, it may be difficult to fix.

How do I prevent the sugar from burning?

It’s important to keep a close eye on the sugar as it cooks, stirring it constantly with a wooden spoon or heatproof spatula. Also, be sure to use a heavy-bottomed pan as this helps with more even heating. If you notice the sugar starting to brown too quickly, remove the pan from the heat and continue stirring.

Why do you add baking soda to peanut brittle?

Baking soda is a crucial ingredient in peanut brittle that helps to create its characteristic light, airy texture. When added to the hot sugar mixture, baking soda reacts with the acids present in the mixture and releases carbon dioxide gas. This gas creates small air pockets throughout the brittle, making it more porous and less dense.

How do I store peanut brittle?

Once the peanut brittle has cooled and hardened, you can break it into pieces and store it in an airtight container at room temperature for up to 2 weeks. Be sure to separate the layers with wax paper to prevent sticking.

INGREDIENTS NEEDED: (SEE RECIPE CARD BELOW FOR THE FULL RECIPE)

  • sugar – granulated sugar, you gotta use the real stuff here not sugar substitutes.
  • light corn syrup – corn syrup is not high fructose corn syrup, again no substitutes here.
  • salt – this balances the sweetness from the other ingredients
  • unsalted butter – you can use salted butter and just leave out the salt in the recipe
  • unsalted, dry roasted peanuts – you could technically use raw peanuts but they can give some folks a stomach ache who are sensitive to raw nuts so I stick with the roasted, you could use salted roasted peanuts as well
  • baking soda – this is essential so make sure the baking soda you are using is fresh
sugar, light corn syrup, water, salt, unsalted butter, unsalted dry roasted peanuts, baking soda.

HOW TO MAKE HOMEMADE PEANUT BRITTLE:

Line a large cookie sheet (17.25 x 14.9 inch) with parchment paper and spray with nonstick cooking spray. This stuff is sticky and we want to be extra safe in making sure it will release from the pan. In medium saucepan, stir together the sugar, corn syrup water and salt then bring to a boil over medium heat. Hook the candy thermometer to the inside of the saucepan.

When the sugar comes to a boil (about 6 to 7 minutes) add the sliced butter. Stir to combine.

Continue boiling the mixture until the candy thermometer reads 300°F (this is called the hard crack stage). Remove from heat and stir in the baking soda. It will get fizzy.

Notes

  • BEFORE MAKING: Please refer to my FAQ’s (Frequently Asked Questions) for the answers to the most common questions and to ensure this turns out properly for you.
  • You must use a candy thermometer and work in a low humidity environment for the brittle to set up. I can’t stress this enough. Don’t try to do this without a candy thermometer unless you are already a master at making brittle and know the exact consistency to look for. If the brittle does not reach a hard crack stage (300F degrees) it will not set up and harden properly.
  • Also, the correct pan size matters. If your pan is too small then the brittle mixture will be too thick and won’t be able to harden up properly. 
  • If you like it to have a more salty flavor, you can use salted peanuts.

  1. the only thing I did different was after I poured it into the lined cookie sheet , was to allow it to cool about to the point that it starting to harden then take a pizza cutter and quickly run down the length and width a couple of times.
    it makes for less sharp edges and uniform pieces…… just a guy thing

    This was my first time making brittle and this recipe was easy. The peanut brittle turned out perfectly! I was very happy with the results.

  3. 5 stars
    It came out perfectly loved it easy recipe too made a batch last night and almost finished with another batch tonight. Just wonderful.

    Wow, this was so good! Made it with dairy free butter and lightly salted peanuts. I didn’t have a candy thermometer so had to use a meat thermometer – it worked but I don’t recommend that. Gave some to a friend who was having a stressful day and had to give him an additional bag of them because he couldn’t stop raving about how yummy it was.

    This recipe is a keeper!

    My daughter whose favorite candy is peanut brittle, says that this is the best peanut brittle that she has ever had.

    This is the perfect brittle recipe! I didn’t have light syrup so I used dark and it still tastes great.

      Hey Judy, I believe that Karo brand used the terms “light and dark” to refer to the color of the corn syrup. Not that it has less calories.

      1. Thank you. I believe the ones I see in the grocery store are light, even if it doesn’t specifically say that.
        Going to give this recipe a try for sure!

    Thanks Brandie! Wanted to make some peanut brittle this year for Christmas gifts and this one looks perfect! I think that it would be easier to get out of the pan if you line it with foil and then oil that though. I do that with English Toffee and haven’t had any issues. And that way you can just lift it out to break it up. Just a suggestion.

    1. You can use foil or parchment paper like I use in this recipe. Both work. I think sometimes foil likes to break apart when you go to remove it so that is why I prefer parchment paper. Wax paper, however, should not be used.
