Peanut Brittle is a delicious, old-fashioned, buttery treat made with simple ingredients and peanuts. This heirloom peanut brittle recipe is always a favorite!
This candy confection is simple to make and has a great buttery, nutty flavor such as homemade toffee. It’s a tradition in my family to make for the holidays such as divinity, date nut roll, or rich fudge.
Peanut brittle has always been a favorite in my family. It’s such a rich, delicious homemade candy we’ve loved for generations! I remember my Grandmother and then my Mama making this heirloom recipe every fall and Christmas season to take to parties and give to friends and neighbors as gifts.
The peanut brittle-making tradition has now come full circle.
Peanut Brittle Recipe
I began my own tradition of making this decadent yet humble confection many years ago. With special memories of watching my grandmother and mother make it, I added to those in my own kitchen. After each fresh batch of peanut brittle had safely cooled, I enjoyed watching my son’s face light up as he was always the first to get to sample this delicious treat! The buttery rich brittle surrounding the salty peanuts literally melts in your mouth!
What We Love About this Peanut Brittle
- Old Fashioned Favorite – As I mentioned, this is one of those candies that bring back memories for all of us in my family.
- Simple, yet Scrumptious – It’s very simple to make and made of simple ingredients but has a wonderful buttery crunch that everyone loves!
- Stays Fresh a Long Time – If kept in an airtight container, this lasts for several weeks so it’s great to make to enjoy throughout the holidays as well as to share with friends.
- Allergy-Friendly Option – You can also easily make this peanut brittle without peanuts as a nut-free, allergy-friendly option!
How to Make Peanut Brittle
Rich, buttery, and absolutely delicious, this peanut brittle recipe is a treasure.
Let me share how my family has made it for such a long time.
Ingredients and Tools
To make this brittle, you will need the following:
- Granulated sugar
- Light corn syrup
- Water
- Salt
- Butter – I always use salted butter, but you can use unsalted if you wish.
- Baking soda – It causes a chemical reaction that is important for making the brittle have the right texture and bite.
- Vanilla – I use my homemade vanilla, but you can also use a quality store-bought pure vanilla extract.
- 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. If using raw peanuts, make sure to use room temperature peanuts, never frozen peanuts.
- Candy Thermometer – I also recommend having a candy thermometer to make this peanut brittle. You’ll find that this is a great tool to have on hand and makes candy making so much easier.
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 then cook over medium heat for about three minutes, do not stir.
Check temperature. Continue to cook, occasionally stirring until the mixture reaches 300º 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.
Can You Make Peanut Brittle Without Peanuts?
To make an allergy-friendly peanut brittle, simply 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 into the brittle)
- Pistachios
- Other nuts, such as Almonds, Walnuts, or Cashews
How to Store Peanut Brittle
To Store – Once it has 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 area of the kitchen, such as a cabinet near your stove.
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.
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 certain of a couple of things so that you can protect your candy when you freeze it. First, make sure it is completely cooled before packaging it for the freezer. Then make sure that the bags or containers you are using to place in the freezer are absolutely airtight. If bagging, make sure to press any air out of the bags before sealing. Once you place the cooled brittle in your freezer-safe, airtight container and freeze it should last for up to 3 months.
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. Definitely 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 a bit once it’s added when cooking. It helps the peanut brittle to have the right texture.

Tips!
- Use a Candy Thermometer – they are inexpensive, and an important candy-making tool to ensure your ingredients have reached the correct temperature.Â
- Cold water test – If you do not have a candy thermometer and can’t grab one before making it, you can test your peanut brittle using a cold water test. Drop a small amount of the sugary syrup into a small bowl or glass of very, very cold water. The syrup with solidify but will still easily separate into hard, brittle threads.
- Don’t skip the baking soda -it’s an important ingredient that matters to the texture of the candy.Â

Yes it’s definitely delicious
So glad you like it, Candy! Thanks!
I am an old man who loves to cook. This recipe looks like the recipe my Mom made when I was young. So much better to use Baking Soda and when it bubbled, then she would stretch it with a fork. In her later years she changed to cocktail peanuts. My sister made Mom’s Christmas treats every year and brought them when she made family visits. She is gone now so her husband has continued the tradition and makes the treats at his home 400 miles away and visits each of us. We look forward especially to the Peanut Brittle, spiced nuts, and caramels although he struggles with the caramels.
You can use other nuts,as well..i do love me some peanut brittle, but i love pecan brittle also! UM, UM!
I found out just last week that Jacob is a huge Peanut Brittle fan. Guess what I’ll be making soon? Thanks for the recipe!
When you find out little nuggets of information like that, doesn’t it make you want to rush into the kitchen to make it for them? I sure hope he loves it! xo
Many years ago, I had a recipe that I made in the microwave, and I’ve lost it. I made it for my father who sadly can no longer eat it. I like this classic recipe.
Thanks so much, Carolyn! This recipe is one my family has enjoyed for many, many years. I hope you like it as well! xo
I have made peanut brittle for years and years and am famous for mine. I want to stress how important it is to stir in the soda and quickly pour the peanut brittle onto the cookie sheet. This prevents it from being too hard. It turns out crunchy if you get it out of the pan while the soda is still bubbling. I hope this was helpful to beginners.
Thanks!
Looks yummy! I’ve never had much luck with candy thermometers tho’. I’ll just keep making it in the microwave and look at your pretty pictures and wish mine look that good! lol. Thanks for sharing tho’ the recipe is slightly different then most I’ve seen.
I love peanut brittle. And so does my dad. Thank you very much for your recipe. Going to make it today, (before my Dad feeds all my raw peanuts to the neighborhood begging squirrel!!!) haha. Thanks again.
Hi Robyn ! Please reply to my message below.:)
I tried making it and it did not turn out nothing like yours.
The color is white, the texture is granny a little and it’s not hard what so ever! As I am typing this I had to put it in the freezer because it was not hardening within those 15-30 minutes!! Why?
I followed all your given instructions but, I made simple light corn syrup ( 1 cup sugar and 1/4 cup water over low heat)
And I didn’t have any baking soda so, I used 4 teaspoons of baking powder instead of baking soda. But, I didn’t have a candy thermometer. So, why did this happen? What should I have done? What should I do now? Should I do the microwave version instead? Lease be very specific and very informational !!!
I am still looking forward to try to make it again soon as possible!!!
Thank you!!!
Hi Grace,
I hate it when I’m trying to make something and it doesn’t turn out just right! I feel for you! You needed to use baking soda rather than baking powder in this recipe and I recommend that you use the corn syrup versus the simple syrup that you made and included. The recipe is sometimes forgiving, but you need to use the ingredients listed for it to turn out like mine. I wish I could tell you that microwaving it would salvage it at this point, but I’m just not sure.
Warmly,
Robyn xo
I made the peanut brittle last night and it turn out pretty good. What I done was left the candy out all night until I got up this morning and broke into pieces. I did notice that when I tried a piece it was a little chewy so I decided to put the remaining pieces of the candy in the fridge to harden and it worked for me. I love it!
I’m so glad you tried it and hope you will continue to enjoy it! It’s such a family favorite, especially during the holidays! Thanks! xo
I’ve never tried to make peanut brittle, but I sure do love it!
