Peanut Brittle has always been a special treat during the holiday season. This buttery Peanut Brittle Recipe will become a yearly holiday favorite, plus it’s the perfect sweet treat to package up and share as an edible gift.

Growing up the appearance of rum balls, toasted pecans and peanut brittle meant it was Christmastime. Each year they were a constant on the buffet of goodies. Other treats would come and go, but that trio was a given every year in our home during the holiday season.

I remember watching and smelling the rum balls and roasted pecans being made, but somehow the peanut brittle seemed to magically appear. Now that I am older and can make it myself, I imagine my grandmother probably made it after we went to bed to avoid distractions or any mishaps from little ones tugging on her apron. Although it is quick to make, it requires constant attention and is a very hot endeavor. It’s not a recipe I would call kid-friendly, except the end part—the crushing of the brittle. That part is totally kid-friendly! Be sure to follow the detailed recipe along with the helpful notes below and you’ll be right on your way to perfect peanut brittle in no time.

How to Make Peanut Brittle

Peanut Brittle Recipe Ingredients

  • granulated sugar
  • light corn syrup
  • water
  • butter
  • salt
  • vanilla extract
  • unsalted dry roasted peanuts
  • baking soda

Peanut Brittle Recipe Instructions

  1. Line a large rimmed baking sheet with baking parchment paper, a silicone baking liner, or butter very well. Do NOT use waxed paper. Set aside. Make sure you have all tools and ingredients measured and ready to go because once you begin, it’s a very quick process. Be sure to read the recipe notes below.
  2. Combine sugar, corn syrup and water in a medium heavy bottomed saucepan. Bring to a boil over medium-high heat. Stir occasionally, until sugar is dissolved.
  3. Insert candy thermometer.
  4. Stir in butter and continue cooking, stirring occasionally.
  5. Next, when the candy thermometer reaches 280-degrees F, stir in the salt, vanilla extract and peanuts. Continue cooking, stirring constantly. Be very careful as each addition will cause the mixture to bubble up.
  6. Once the candy thermometer reaches 300-degrees F, remove the pan from the heat and stir in the baking soda. Again, be careful as the baking soda will cause the mixture to foam up.
  7. Carefully and quickly pour the hot mixture onto the prepared baking sheet. Use a rubber spatula to quickly spread the mixture evenly across the baking sheet. Allow to cool completely.
  8. Finally, once brittle has completely cooled, break it into pieces, then store in an air-tight containers for up to 2 weeks.

As you can see, this Peanut Brittle Recipe isn’t complicated. The important part is being totally prepared before beginning and being ready to be present and watchful during the whole process. Once you begin the recipe things move rather quickly. After making a few batches I hope you’ll see how easy it is to make and add it to your regular holiday treat lineup.

Peanut Brittle is not only a buttery andcrunchyaddition to any holiday occasion, it is the perfect treat for sharing as an edible gift. It packages well and will last for up to two weeks when stored tightly covered. So whether you’re needing to ship a treat across the country or just walk it next-door to your neighbor, Peanut Brittle won’t disappoint.

A few Peanut Brittle Recipe notes and tips:

  • When it comes to most recipes, having the proper tools on hand always makes for a better time in the kitchen, but that rule especially applies to candy making. Here are a few tools that will help the process go much more smoothly: candy thermometer, tall sided heavy bottom medium (about 3 qt) saucepan, silicone spatula, large 18×13-inch baking sheet, baking parchment or silicone liner (not wax paper)
  • Have all ingredients measured out and ready to go before beginning to cook the brittle. Once temperatures reach 280-degrees F, things progress pretty fast.
  • This is a very hot process. Be careful when adding in salt and vanilla and then again with the baking soda as the mixture will bubble and foam up, releasing lots of steam.

FAQs

Why didn't my homemade peanut brittle get hard? ›

The main reason why peanut brittle doesn't get hard and have the crunch we expect is because the sugar was not cooked long enough. The sugar needs to be cooked to what is called the hard crack stage, 300ºF.

Why put baking soda in peanut brittle? ›

Baking soda is also very important at this stage since it reacts to the heat, creating carbon dioxide that aerates the caramel, enabling it to snap when someone bites into it rather than requiring them to gnaw at it until it breaks or pulls apart.

How do you keep peanut brittle crispy? ›

5 Tips on How to Store Peanut Brittle
  1. #1 - Store in an airtight container. ...
  2. #2 - Separate your brittle. ...

Why is my peanut brittle airy? ›

What is the purpose of adding baking soda to peanut brittle? Once you add the baking soda to the hot mixture, it bubbles up, and the mixture becomes somewhat airy.

Can you salvage undercooked peanut brittle? ›

So, I Googled Salvaging Undercooked Peanut Brittle and followed Tiffany's helpful instructions to throw the pieces back in the pan, turn the heat up and stir, stir, and stir to a raging boil and wait to pour it in the pan until it reaches 300 degrees.

Can you use parchment paper when making peanut brittle? ›

You'll also want to prepare a baking sheet, with either a silicone mat or parchment paper. The mat/paper will help ensure the peanut brittle doesn't stick directly to pan once it has cooled.

What makes peanut brittle too chewy? ›

Why did my peanut brittle turn out chewy? The likely cause is that the sugar mixture didn't reach the proper hard crack stage temperature. Ensuring it reaches 300˚F is key to getting that classic brittle texture.

Should you refrigerate peanut brittle? ›

To store: Store peanut brittle (once it's completely cooled) in an airtight container at room temperature. Do not refrigerate as the moisture from the fridge will cause the brittle to soften. Store for 6-8 weeks. To freeze: Peanut brittle can be frozen and stored up to 3 months.

Why did my peanut brittle crystallize? ›

Cooling down too quickly can prevent the candy from becoming hard. When candy cools slowly on a stone slab, more crystals have a chance to form. With a higher number of micro-crystals, the sugar has more sites on which to crystallize, and so crystallization ultimately happens faster.

Does weather affect making peanut brittle? ›

I've learned that brittle is better when made on a cool, dry day. When I've made the candy on a warmer, humid day, it tends to be a stickier brittle. This is because the brittle takes longer to cool, and it reaches a point where it is no longer evaporating moisture into the air.

What's the difference between praline and peanut brittle? ›

Pralines have a lot in common with nut brittle, with the difference being mostly in the addition of cream and the cooking temperature––the sugary syrup used to coat pralines is heated to a soft-ball consistency, a lower temperature than the hard-crack stage of peanut brittle.

What's the difference between toffee and brittle? ›

Brittles are typically composed mostly of sugar, while toffees contain a fair amount of butter and in some cases milk. This makes toffees fuller and richer in taste, while brittles are more purely sweet and sugary. Brittles are also much thinner than most toffees.

How do you fix stiff peanut butter? ›

After softening in the microwave, I would recommend mixing in some oil that isn't too flavorful. I found mixing in a bit of water works fine though. You could even make your own mixes to make that last little portion of nut butter count by mixing in honey, unrefined coconut oil, or even Nutella if you so desire!

Why is my homemade peanut butter so dry? ›

Since oil and water don't mix, and peanut butter has a high oil content, there isn't much room in the mixture left over for water, explains Live Science. This can lead to naturally dry peanut butter, drying out more quickly due to its limited water content.

Why did my peanut butter fudge not get hard? ›

The main reason is that your Fudge has not reached the optimum temperature. If your mixture only reaches 110 or 112 degrees Celsius it will always be soft. That's why we recommend investing in a sugar thermometer. Another reason your Fudge is not setting is that the ratio of liquid to sugar is too high.
