Learn how to make old fashioned peanut brittle in a few, no fail, easy steps! This homemade peanut brittle recipe has been made countless times and always turns out perfectly time and again.
Around our house, holiday season isn’t complete without several batches of old fashioned peanut brittle. Making this homemade gift started when I was a child and now continues with my own family.
Growing up, every year our teachers looked forward to receiving a tin filled with addictive, crunchy peanut brittle from us. Since there were six of us, however, they inevitably feigned surprise when they opened our Christmas gifts.
Why Homemade Peanut Brittle Makes the Perfect Gift

Equipment Used For Making Homemade Candy
Making peanut brittle requires a baking sheet, a saucepan, and a candy thermometer.
✽Candy Thermometer – This is the most paramount equipment when making any candy, such as fudge, toffee, or brittle. Temperatures must be spot on for the recipe to work.
For years I used an inexpensive candy thermometer that clips onto the side of saucepan. This worked to achieve results, but it was very frustrating to work with.
These types of thermometers have to be submerged in the liquid the whole time in order to slowly and gradually read the temperature. This means it won’t read the temp quickly enough to just dip it in time from time.
Plus, it’s awkward to avoid hitting while stirring. So, I’d hold it in place with one hand, while stirring with the other.
Also, clipping the thermometer in place may skew readings. Temperature is measured for that location only.
I upped the ante recently and purchased a Thermapen Mk4, which I’ve been eyeing since it’s always featured in Cook’s Illustrated and America’s Test Kitchen. Best. Purchase. Ever.
This instant read thermometer gauges an absolutely spot on temperature in only two seconds! Therefore, dip in and out periodically instead of holding it in the pan.
A Thermapen has many other uses. Besides candy making, I use my Thermapen for meat temperatures, water temps when proofing yeast, testing oil temperatures for frying, making yogurt, and tempering chocolate.
✽Saucepan – Ideally use a heavy-bottomed saucepan to conduct heat evenly and prevent scorching the sugar. I truly believe great cookware makes an immense difference with results. Personally I use the Calphalon Tri-Ply Stainless Steel set, because it’s affordable compared to flashier brands, performs fantastically, and will last a lifetime. I used the Calphalon 2.5 quart saucepan for this recipe.
✽Baking Sheets – Although any baking sheet will do because it’s simply used to cool the peanut candy, Nordic Ware baking sheets are rated the best in Cook’s Illustrated, are very affordable, and great for baking.
How to Store Peanut Brittle
Peanut Brittle has a long shelf life. It lasts a couple months if properly stored in an airtight container. Simply place brittle in a completely dry container (ie. food storage container, lidded jar, or tin) away from extreme temperatures.
Can Peanut Brittle be frozen or refrigerated?
Do not freeze or refrigerate the brittle because of the humidity and moisture. The peanut brittle will become sticky and lose its crunch.
Tips / Tricks and Problems Solved for Old Fashioned Peanut Brittle Recipe
When making any candy make sure all the ingredients and equipment are ready to go before starting. Timing is crucial and this will avoid any mishaps.
Use a bigger saucepan, at least triple the volume of the ingredients. The boiling syrup increases in volume, so there has to be ample room for expansion.
Do not double or triple the recipe. Make one batch at a time. Luckily the process goes quick!
Can parchment paper or a silicone mat be used instead of greasing the pan? Yes, but DO NOT USE WAX PAPER, which will melt and stick to the peanut brittle.
If you prefer more nuts to candy ratio, increase the amount of peanuts up to 1 1/2 cups.
Why Is My Peanut Brittle Chewy / Sticky / Didn’t Harden?
This is a temperature issue. Make sure the candy reaches exactly 300ºF / 149ºC, which is hard crack stage, before pouring onto baking sheet. See “Equipment Used to Make Peanut Brittle” for my recommended thermometer.
If you’re peanut brittle is still chewy after it cools, you may be able to save it! First test your thermometer in a saucepan of boiling water for a few minutes.
It should read 212ºF (100ºC). If not, calibrate accordingly so you know what the “true” 300ºF is on your thermometer.
Break up the peanut brittle and place it back into a clean saucepan. Very gently reheat it, stirring constantly, until it liquifies again.
Continue heating over medium heat until it reaches the adjusted 300ºF temperature. Remove from heat and add additional 1/2 teaspoon of baking soda. Pour onto prepared and let cool again.
Substituting Different Nuts for the Peanuts
Wondering if different nuts may be substituted? Yes!
Any preferred nut will work, such as cashews, almonds, pecans, hazelnuts, or mixed nuts. The nuts should measure 1 – 1 1/2 cups total.
HOW TO MAKE PEANUT BRITTLE RECIPE
Butter a baking sheet and set aside. Alternatively use parchment paper or a silicone baking mat.
In a large saucepan combine sugar, corn syrup, water, and salt over medium heat until sugar is dissolved.
Bring to a boil and stir in peanuts. Continue cooking over medium heat, stirring, and checking temperature. Cook, stirring constantly, until thermometer reads exactly 300ºF / 149ºC.
Remove from heat. Stir in baking soda and room temperature, softened butter. Pour onto buttered baking sheet.
Spread hot mixture out. As it starts to cool, pull with a fork to stretch out more.
Cool completely and break into large pieces.

Immediately remove from heat and stir in butter and baking soda vigorously. (Be careful it will boil up and expand) Pour onto the prepared baking sheet. Spread with a silicone spoon, then pull more with a fork, until it almost fills up the baking sheet.
Cool and break into pieces. Store in tin or another airtight container.

Hi Lana, No, it doesn’t include vanilla extract, but definitely wouldn’t hurt to add it! If you do, add it when you stir in the butter and baking soda. Best, Melissa
Omg!! I have always been intimidated by peanut brittle! 🤭 this was a no fail, perfectly delicious brittle! If I can do it, anyone can do it! Thank you for this recipe!
I have found that most peanutbrittle recipes are in general are the same. I my opinion it’s the “tweaks” that separates it from the other’s. I see people using sauce pans. CAST iron works much better in my “opinion “. It distributes heat better. Mine is a 100 year old wagner which grandmother used mother used now I use. I only use it to make my peanutbrittle. I don’t use thermometers. They are sometimes inaccurate and they break. And they get in they way. I was taught to go by sight and smell. And you are missing out if you don’t use pure Mexican vanilla. I use a pizza pan buttered and put in the freezer until you are ready to use it. This is all just my opinion.
Hi Tim! Thank you so much for all those tips. I think the pan does make all the difference when cooking candy. The heavier the better, so cast iron would be great! Do you use a shallow cast iron pan, like a skillet?
Hello! Thanks for responding my skillet is a fry pan 2″ deep. It is just my opinion but what I have written works for me. I have about 150 customers who will agree.
Salted peanuts. Not dry roasted, but the kind in the can. You can use cocktail peanuts, Spanish peanuts, or another preferred nut, like cashews. I’ll clarify in the recipe. Thanks!
Just got done making this. It was my first attempt at peanut brittle and turned out great! Thank you. The only problem is that I can’t stop eating it. I want to give it as gifts but I’m not sure it’ll last that long.
That’s funny! When I make it I have to hide it from my husband or he will eat the entire thing before I can wrap it up and give it away! So glad you are enjoying it!
I really appreciate you taking the time to let me know. That always makes my day! I just wrote out my holiday baking list, and I don’t think there has ever been a year I haven’t made this.
Lana says
So there is no vanilla flavoring or did I missit ?
