There’s nothing better than homemade candy, some of our favorites include rocky road fudge and buckeye balls. Peanut brittle is also at the top of our list, and it tastes so much better when you make it yourself!
Peanut brittle is my mom’s favorite candy, but to be honest, it’s never really been my thing. I made this recipe for her, and let me tell you, it’s the best peanut brittle EVER. I’ve eaten way too much of it over the last few days, and that’s coming from someone who doesn’t even like this candy!
How do you make peanut brittle?
Peanut brittle is easier to make than you’d think. Corn syrup, salt, sugar and water get boiled, then butter and dry roasted peanuts are added to the mix. Everything gets cooked together until a rich and golden brown candy forms. The final step is a touch of baking soda. The peanut mixture gets poured onto a sheet pan and then it needs to cool completely before you can break it into pieces.
The trick to making peanut brittle is to get yourself a candy thermometer. This is a necessary tool for successful peanut brittle. Luckily, candy thermometers are inexpensive and widely available. Be sure to monitor the temperature of your sugar mixture carefully so that you don’t overcook or undercook the brittle. If you overcook your brittle, it could become bitter or burn, and if you don’t cook it for long enough, it can get sticky.
Why do you use baking soda in peanut brittle?
Baking soda may seem like an odd ingredient to put into candy, but the baking soda creates a ton of tiny air bubbles that improve the texture of the brittle. Don’t be tempted to skip this step!
Tips for peanut brittle
- Not a peanut fan? You can substitute an equal amount of pecans or almonds for the peanuts.
- Peanut brittle can be stored in an airtight container at room temperature for up to 1 week.
- Use a bigger pot than you think you need for this recipe, as the sugar mixture expands quite a bit, especially after you add the baking soda.
I love to package peanut brittle in gift tins and give it away to family and friends during the holidays. This candy is so much better than any store bought brittle I’ve had, and dozens of people ask me for the recipe as soon as they get a taste of this delicious treat!

I have just finished making it and was wondering how long i should leave it for and if i should put it in the fridge?
Sara says
Let it sit until it hardens and you can store it at room temperature or in the fridge, either is fine.
Jill says
Great recipe, the only thing I do differently is start adding peanuts (that i roast with sea salt and cayenne pepper, ) once it’s at 240. I add 1 tsp vanilla after the baking soda which I also added 1/4 tsp extra. Two thumbs up from a pastry chef
Marta Briseno says
I made half a batch. Substituted the water with a chocolate coffee and used pecan pieces since I didn’t have peanuts . Superb flavors!
Dolores says
Best peanut brittle I’ve made yet! I used Spanish peanuts and found out to add them slowly so the temp doesn’t drop too much. My husband loves it. Our third batch since Christmas and its only jan 16.
Pennie says
This was outstanding. I used 3 cups of Fisher oven roasted never fried peanuts, lightly salted with sea salt. I increased the baking soda by 1/4 tsp because I love, love, love the air bubbles.
Thank you so much for sharing. This is even better than Williams Sonoma peanut brittle!
Shyrene Thompson says
I made this recipe, it was fantastic!! Best recipe ever!! My husband who doesn’t really love peanut brittle said it was the best he has ever had. Thanks for sharing the recipe.
Kelly Starkey says
I’m making this now. I can’t get candy thermometer to go over 220. It’s been about 20 minutes?
Sara says
Do you have the heat on high and what type of thermometer are you using, I wonder if it’s not working properly. Sometimes the mixture will stall out for a bit before the temperature starts climbing again. Also make sure the bottom of the thermometer is not touching the bottom of the pot as that can give you an incorrect reading.
KJ says
Looking forward to trying this! Just wondering with the 1 cup butter, how many table spoons would this be? Just don’t want to add too much and ruin the recipe!
Sara says
16 tablespoons!
Lea says
I only have golden corn syrup, will that work?
Sara says
Are you talking about Karo corn syrup or like a golden cane syrup?
Carol Lazzaro says
Hello!
I have dry roasted peanuts but they are lightly salted……is this ok to use?
Thank you,
Carol Lazzaro
Sara says
yes that’s fine!
Christine says
Thank you! I made a half recipe this morning to try it out. I’ve never made peanut brittle or any hard candies before. Using my moms antique candy thermometer, the peanut brittle turned out perfect! Next time will be a double batch!
Lisa says
What size pan should I use?😳
Sara says
Use a sheet pan, mine measures 13×18 but anything around that size is fine!
Angie says
Just made a batch (long-time baker, first time at peanut brittle) & wow, it’s fantastic. Easy recipe to follow. I mixed peanuts & cashews. Pinned this one for sure!!
Tabitha says
My husband loved this recipe! I made one batch of peanut brittle and one batch of cashew brittle using same recipe just substituting cashews for peanuts.
