Peanut Brittle

Jump to Recipe

I have fond memories of growing up and eating delicious treats during the holidays. My mom made three amazing candies every year. We also had old-fashioned fudge, Almond Roca, and of course classic peanut brittle. I think my love of candy and treats came from my mom. Thanks, mom!

While we are on the topic of holidays, we always had this amazing homemade cinnamon raisin bread. Either she would make it, or I would make it. But this post is all about classic old-fashioned peanut brittle.

Peanut brittle is one of the most popular treats to have during the holidays. It is a quintessential holiday candy. And it is fairly easy to make too, if I can do it, you can do it. Let’s get started!

Step 1: Gather the ingredients

Several ingredients in bowls on a white countertop.

In order to make classic old-fashioned peanut brittle you need just a handful of ingredients:

  • Sugar – Use normal white granulated sugar.
  • Corn syrup – Light corn syrup is the best to use. Glucose syrup will work as well. I haven’t tried agave nector, brown rice syrup, or golden syrup, but those may work as well. The corn syrup helps prevent the sugar from crystalizing. Making a better nut brittle.
  • Water – I always use filtered water, because my tap water is gross.
  • Salt – It will enhance the flavor.
  • Peanuts – Raw peanuts are the best to use, but those can be hard to find, so dry roasted peanuts can always be used.
  • Butter – This will add flavor! Use salted or unsalted butter.
  • Baking soda – The baking soda makes the brittle lighter and more airy it is a key ingredient in peanut brittle. Don’t leave it out, and don’t use baking powder.
  • Vanilla extract – This adds flavor.

  • Candy thermometer
  • Large pot
  • Silicone spatula or wooden spoon
  • Forks
  • Sheet pan
  • Cooking spray, shortening, or butter, or parchment paper

Step 2: How to make homemade peanut brittle

Hand stirring a pot of sugar and corn syrup next to a bowl of peanuts.

First, measure out all your ingredients. You want to have them handy and ready to go. Otherwise, you will waste time trying to measure, and your peanut brittle might burn in the process.

Prepare a sheet pan by either buttering it, spraying it with cooking spray, or laying down a sheet of parchment paper. You can also use a cookie sheet as well.

Add a medium or heavy bottom pot to the stovetop burner. Set the heat to medium. Do not be tempted to set the heat higher than that.

Add the sugar, salt, and corn syrup to the pot.

NOTE: If you are using raw peanuts at those at this time as well. Dry roasted peanuts will be added later.

Hand checking the temperature of melted sugar solution.

Stir the sugar and corn syrup occasionally until the temp starts to boil and reaches around 250 F/121 C. If sugar crystals are stuck to the side of the pot, use a basting brush dipped in warm water and brush the sugar down.

NOTE: It is essential that you use some sort of candy thermometer or even a meat thermometer will work.

Once it reaches that temperature, add the dry roasted peanuts and stir constantly the remaining time. If you don’t stir constantly the candy will burn.

It will take about 20 minutes total cooking time from start to finish. Keep stirring and heating until the candy reaches the hard crack stage (300 to 310F/148 to 154C)

Stirring and checking the temperature of the peanut brittle.

Step 3: Finish the classic peanut brittle

Once the peanut brittle gets to between 300 F and 310 F remove it from the heat and turn the heat off. Quickly add the butter, baking soda, and vanilla extract. It will bubble up on you most likely. This will change the texture a bit and give it that classic peanut brittle texture and taste.

Hands with forks pulling the peanut brittle apart.

Once completely mixed in, pour it out onto your prepared sheet pan or cooking sheet. Use forks to spread it apart making the candy thinner. Also, this allows you to even out the peanuts.

Allow the fresh homemade peanut brittle time to cool completely. At least 30 minutes.

Now you can break the peanut brittle apart into smaller pieces and serve it. You can place pieces in small mason jars or other containers and give them as gifts if you like. They make great gifts.

Enjoy your homemade peanut brittle!

How long does homemade peanut brittle last?

If stored in an airtight container it will last 4 to 6 weeks. But I doubt it will go past a week, haha. Do not store it in the fridge.

  • Candy Thermometer
  • Large Pot
  • Silicone spatula or wooden spoon
  • Forks
  • sheet pan
  • Cooking spray, shortening, or butter, or parchment paper


  • 1 cup white granulated sugar 200g
  • 1/2 cup light corn syrup 160g
  • 1/4 cup water 60ml
  • 1/8 tsp salt
  • 1 cup dry roasted or raw peanuts 150g
  • 1 Tbsp of butter salted or unsalted (15g)
  • 3/4 tsp of baking soda 3g
  • 1 tsp of vanilla extract 5ml


  • Butter a baking sheet or cookie sheet or line it with parchment paper.
  • Measure out all of the ingredients and have them ready to go.
  • Place a medium to large heavy bottom pot on the burner and set the heat to medium.
  • Add the water, sugar, corn syrup, and salt to the pot. If you are using raw peanuts add them now. Stir and combine.
    Heat the mixture to 250 F/121 C. Stir occasionally. Wipe down any sugar crystals if they form on the sides of the pot with a damp basting brush.
  • Once the sugar mixture reaches 250F add the dry roasted peanuts if using those. Stir constantly until the brittle reaches 300F to 310F (148 to 154 C)
  • Remove from heat and quickly add the vanilla, butter, and baking soda. It will most likely bubble up on you, this is natural. Stir really well until combined. Be careful! The candy is hot.
  • Pour peanut brittle onto the prepared baking sheet. Spread it out with forks to make it thinner and to even out the peanuts, if desired.
  • Allow peanut brittle to cool completely, about 30 minutes. Then break it apart and serve.

    Matt your classic recipes never disappoint! This was so good – we drizzled chocolate over top too because I just felt a bit creative. It turned out perfectly and will add this treat to our neighborhood cookie exchange next month. Thanks!
