How to make Peanut Brittle

Homemade candy is a favorite during the holiday season – hard candy, crockpot peanut clusters, peanut butter fudge, and this old fashioned peanut brittle recipe.

I loved Planters Peanut Bars when I was little but I don’t think they make them anymore. This peanut brittle is similar and so easy to make yourself!

You do need to use a candy thermometer but don’t let that intimidate you. You’ll be fine as long as you don’t get distracted (speaking from experience).

Why you’ll love this Easy Homemade Peanut Brittle

Easy Recipe – Candy making doesn’t have to be intimidating, this one is a breeze! Even if this is your first time making candy, you’ll be fine.

Simple Ingredients – You only need a handful of ingredients, six to be exact, that you likely already have on hand.

Family Favorite – This candy recipe is great any time of year but makes a great holiday gift if you bag it up into treat bags to pass out.

Equipment you’ll need

  • Baking Sheet – Use a lipped baking sheet to keep the peanut brittle on the pan.
  • Candy Thermometer – Nothing fancy, you just need a basic one, but it is helpful to have a clip to hook to the pot.
  • Silicone Spatulas – I use these for everything in the kitchen.

Ingredients

Below is a list of the ingredients you’ll need to gather to make this recipe.Scroll all the way down for the full recipe card.

  • SUGAR – Granulated white sugar.
  • CORN SYRUP – Use light corn syrup. I use Karo syrup.
  • WATER
  • BUTTER – Unsalted butter, cubed.
  • BAKING SODA – The baking soda creates a chemical reaction causing little air bubbles to form. The candy becomes porous and brittle, making it easy to break into pieces.
  • PEANUTS – I like to use roasted peanuts for flavor but raw spanish peanuts were traditionally used.

How to make peanut brittle

This brittle candy is so easy to make, but it does require you to watch the temperature so don’t get distracted!

  1. STEP ONE: Grab a large cookie sheet with sides (like a jelly roll pan) and cover it with foil. Spray with nonstick cooking spray and set aside.
  2. STEP TWO: Stir together the sugar, corn syrup, and water in a medium saucepan. Bring the mixture to a boil and continue to boil until the temperature reaches 340 degrees F. It should be golden brown after about 15 minutes.
  3. STEP THREE: Remove the pan from the heat and add butter and baking soda. It will bubble up (that’s the chemical reaction) so work quickly stirring with a silicone spatula until smooth.
  4. STEP FOUR: Pour in the peanuts and stir to evenly distribute. Quickly pour the peanut brittle mixture onto the lined baking pan and spread it evenly into a thin layer.
  5. STEP FIVE: Let the candy harden, at room temperature (about 30 minutes), and then break into pieces and store in an airtight container.

Which types of nuts should I use?

Peanuts are the classic choice to use in nut brittle. Roasted peanuts have great flavor. Raw Spanish peanuts were traditionally used but either work. You could also use almonds, cashews, macadamia nuts, pecans…just about any will work.

What does baking soda do to peanut brittle?

Baking soda might seem like an odd addition to the peanut brittle and not everyone adds it, but baking soda creates a chemical reaction that creates little air bubbles. It is added once the sugar mixture has cooked down and becomes acidic. The candy becomes porous and brittle, making it easy to break into smaller pieces.

Why is my peanut brittle chewy?

There is where the candy thermometer becomes important. The biggest reason your peanut brittle is chewy and sticky is because you didn’t cook it long enough. It’s not something you can guess at, you need it to reach the hard crack stage. that means the strands of sugar break easily and feel dry, as opposed to sticky.

If you take it off the heat too soon, it doesn’t set up and makes a sticky mess, but let it cook too long and it becomes scorched and bitter.

Another possible cause might be humidity in the air.You should store finished peanut brittle in an airtight container so humidity doesn’t get to it.

How long is it good for?

When stored in an airtight container, at room temperature, peanut brittle will keep for 6-8 weeks. Do not put it in the fridge as it as the moisture will cause the brittle to soften.

Itcan also be frozen and stored up to 3 months.

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.

What happens when you add baking soda to 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.

Why did my peanut brittle not turn brown? ›

If you have this issue, next time, use a thermometer to make sure the peanut brittle mixture gets to 300°F. Why is my peanut brittle light colored? That's because you did not heat the mixture up enough, and the sugars did not fully caramelize. This is what gives peanut brittle the beautiful golden brown color.

How do you keep peanut brittle crispy? ›

Lastly, avoid making brittle in a humid environment. The candy will attract moisture from the air, making it unpleasantly sticky instead of shatteringly crisp. Once it's completely cool, transfer it to an airtight container.

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.

Why is my peanut brittle still soft? ›

Didn't combine ingredients right. Didn't get it hot enough. You have to hit hard crack stage heat or it's not going to harden.

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 hard but sticky? ›

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 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.

How can you tell when peanut brittle is done without a thermometer? ›

However, if you don't have a candy thermometer, it's still possible to make this sweet. All you have to do to find out if your peanut brittle is ready to be removed from the heat is to drop a bit of the syrup into cold water and see if it forms brittle strands. If so, you're ready to finish up your confection.

Why is my peanut brittle too thick? ›

As mentioned in “how to make peanut brittle”, it's very important to move fast after the peanuts and baking soda are mixed in. If not, the peanut brittle will turn out too thick and clumpy. Don't play the guessing game and use a candy thermometer instead. This will ensure your peanut brittle turns out perfectly golden.

Does weather affect making peanut brittle? ›

I've learned that brittle is better when made on a cool, dry day. When I've made the candy on a warmer, humid day, it tends to be a stickier brittle. This is because the brittle takes longer to cool, and it reaches a point where it is no longer evaporating moisture into the air.

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.

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.

What makes peanuts extra crunchy? ›

How do you make peanut brittle hard again? ›

- Preheat your oven to a low temperature, around 250°F (120°C). - Break the stale peanut brittle into smaller pieces. - Place the brittle pieces on a baking sheet in a single layer. - Heat the brittle in the oven for about 5 to 10 minutes, checking frequently to avoid overcooking.

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.

Is peanut brittle supposed to be hard? ›

Peanut Brittle is a smooth, flat candy (similar to toffee), with peanuts in it, that is cooked on the stovetop and poured onto a sheet pan to cool. Once it cools it's broken into small individual-size pieces of hard candy and lasts at room temperature for several weeks.

Why did my peanut butter fudge not get hard? ›

The amount of time you cook fudge directly affects its firmness. Too little time and the water won't evaporate, causing the fudge to be soft. Conversely, cook it too long and fudge won't contain enough water, making it hard with a dry, crumbly texture.
