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!

This is the first peanut brittle I have ever tried in my 70 years and it turned out PERFECT!🥰 Made it last year and this. For all you cashew lovers….these nuts are yummy in brittle! 😋😋😋 Also, no problem spreading….just used my wooden spoon and works great. Maybe a little hint…..when you are spreading the brittle, it looks all yucky but it evens out right away! I like it thinner😋 Thanks for this great recipe!

Can I use the fudge wet ball test instead of a candy thermometer?
Sara says
I haven’t herd of the wet ball test, only hard crack and soft crack?
Malynda says
This is the first successful peanut brittle I have made. I have tried other recipes but it never set up. This was just like the stuff I have bought before. I think the butter did the trick. It was hard to spread, but that was because my pot was too heavy for me to hold with one hand. Next time I make this, I will make sure my husband is here to hold the pot while I spread it so its thinner.
Ryan stewart says
I used half cup of cannabis infused coconut oil and half a cup of butter and it turned out great
Diane says
I’ve made this recipe twice yesterday & again this morning, and no problem getting it to set, but it comes out way too thick, it doesn’t spread out, it’ll break a tooth!…any ideas? I’m going to try the Karo recipe, the sugar>syrup ratio is 1-1 whereas this recipe is 2-1.
Sara says
Are you using a spatula to spread it?
Madonna Nicoll says
When you say cool, do you mean refrigerate or leave at room temperature? If room temperature for how long ?This is the 3rd brittle recipe I have tried and even following directions none have set. Please help.
Sara says
I typically leave it at room temperature, although it won’t hurt to chill it!
Angie Colautti says
I put my cookie sheet of brittle out on my deck to cool in this 36″F winter weather. lol Worked perfectly…. I enjoy the thickness of the brittle. It doesn’t seem too hard to break with our teeth.
Angie says
This recipe took alot longer that it was noted. More like almost 1 hour. However, it is so delicious. I used a 10×15″ cookie sheet and it turned out nice and thick.
Darby Warren says
This recipe turned out great!
Donna says
Does this recipe really use 1 cup (2 stick) of butter? Just wondering…sounds yummy but most all other recipes only use 2-4 tablespoons.
Sara says
Yes that is correct.
Janet says
can I use margarine instead of butter?
Sara says
I think it could work but I haven’t tried it this way!
Janet says
I made it with margarine and it worked great. Love this recipe will be making more… I even doubled the batches and made 6 batches….
Nancy says
I have used Imperial margarine for a couple years…works great!
Vanessa Trupiano says
Have you ever used a thick simple syrup as a substitute for corn syrup?
Sara says
I have not, I’m not sure if it would work.
