Peanut brittle has always been a favorite in my family. It’s such a rich, delicious homemade candy we’ve loved for generations! Just as my Mama and Grandmother made it every fall and Christmas, I enjoy making it now for my family and friends!
This candy confection is easy to make and has a buttery, nutty flavor similar to homemade toffee. Salty peanuts are surrounded by a rich, buttery brittle that melts in your mouth!
It’s a tradition in my family to make for the holidays, such as divinity, date nut roll, or rich fudge.
What We Love About this Peanut Brittle

How to Make Peanut Brittle
This old-fashioned recipe is a treasure! Let me share how my family has made it for a long time.
Ingredients and Tools
To make this brittle, you will need the following:
You’ll use granulated sugar, light corn syrup, water, salt, butter, baking soda, and vanilla to make the buttery brittle part.
Peanuts – Use my roasted peanuts, cocktail peanuts, or raw peanuts. The original recipe includes using raw peanuts in your brittle, but I like using my roasted peanuts or cocktail peanuts instead.
Candy Thermometer – I also recommend having a candy thermometer to make this peanut brittle.
Step-by-Step Instructions
Prep. Lightly butter a rimmed baking sheet and set aside.
Cook. Add sugar, corn syrup, water, and salt to a medium, heavy-bottomed saucepan. Stir to combine and cook over medium heat for about three minutes, do not stir.
Check temperature. Continue to cook, occasionally stirring until the mixture reaches 300ยบ F on a candy thermometer.
Remove from heat and add ingredients. Once the temperature is 300 degrees Fahrenheit on your candy thermometer, immediately remove it from the heat. Add in butter, baking soda, vanilla, and peanuts. Stir quickly to combine and then pour onto the buttered baking sheet.
Spread the Candy Mixture. Once the brittle mixture is carefully poured onto the buttered baking sheet, spread it carefully (it’s hot!) and quickly it with the back of a silicone spatula. Allow to cool completely, about 15 to 30 minutes.
Break and Enjoy! Break the cooled brittle into pieces. Eat and enjoy.
Tips for the Best Peanut Brittle
- Be careful with hot candy liquid! As with any time you are cooking or handling kitchen tools, one should be safe. But it is worth mentioning this candy is like molten lava when it reaches the desired temperature on the stovetop of 300 degrees. So please be careful as you stir, pour, and spread this hot candy onto the buttered baking sheet. Keep children at a safe distance as you make this until it is cooled. You will spread this somewhat quickly, too, so just be careful. I like to wear long oven mitts that I can wash.
- Do not use frozen peanuts. They will not yield a crisp brittle due to the moisture in the frozen nuts.
- Use a candy thermometer. These are inexpensive and will show you when your candy reaches the desired temperature, so there’s no guessing. It will be valuable for your candy making!
- Store air-tight to prevent sticky brittle. Keep closed in airtight bags or airtight containers in a cool, dry place, and this will last for weeks. Do not refrigerate either due to the moisture it will absorb.
- Do not skip the baking soda! Candy making, much like baking, involves chemical reactions many times. This is one of those. You will notice the mixture foam once added to the cooking process. It helps the peanut brittle to have the right texture.
Can You Make Peanut Brittle Without Peanuts?
To make an allergy-friendly peanut brittle, omit the peanuts called for in the recipe. You can replace them with other add-ins. I’ve included a list of a few substitutions you may like.
- Pumpkin Seeds
- Rolled Oats
- Bacon (cook and crumble bacon to add to the brittle)
- Pistachios
- Other nuts, such as Almonds, Walnuts, or Cashews
How to Store Peanut Brittle
To Store – Once it is completely cooled and broken into your desired-sized pieces, place peanut brittle in an airtight container and store it on the counter at room temperature for 6 to 8 weeks. Keep it in a dark, cool, dry place and keep it sealed in an airtight container to prevent it from absorbing moisture in the air and getting sticky. Don’t place it in a warm kitchen area, such as a cabinet near your stove.
To Freeze – Moisture is the enemy of peanut brittle as it can make the candy chewy and not crunchy anymore. And the nutty crunch is one of the best parts of this candy! So, you will want to be careful to make sure of a couple of things to protect your candy when you freeze it. First, make sure it is completely cooled before packaging it for the freezer. Then ensure that the bags or containers you place in the freezer are airtight. If bagging, press any air out of the bags before sealing. Once you place the cooled brittle in your freezer-safe, airtight container and freeze it, it should last up to 3 months.
Do Not Refrigerate. It will make the candy soft and sticky and cause it to lose its crunchy texture due to the moisture it will absorb in the refrigerator. The goal is to keep the candy dry and airtight, and it will last several weeks.

It just seems like I cannot get the color dark enough. Tastes OK, but the color is just too light. I even tried to cook it a little longer this time and still not dark enough.
I used light corn syrup, that might be the issue. Should I use dark corn syrup?
Phil, if you cook it til it reaches a temperature of 300ยบ F on a candy thermometer before adding the baking soda, peanuts, and other ingredients, it should be the color in my photos. You can use dark corn syrup if you prefer.
Is it okay to use regular corn syrup rather than the light kind? Thatโs all I have on hand right now. Donโt know that Iโve ever seen light syrup.
Thank you, and I canโt wait to try this recipe!

I use the clear corn syrup, Judy. The brand I use is named light corn syrup. Sorry for the confusion.
If I use raw peanuts as opposed to Planters would I have to put them in sooner so that they cook? I’ve never had raw peanuts but my mom always used raw peanuts in hers.
