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.

It packages well and will last for up to two weeks when stored tightly covered.

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 add baking soda to 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.

Why is my peanut brittle rubbery? ›

Make sure you cook the brittle all the way to 311°F. Undercooking the sugar will result in candy that is too soft or chewy.

How do you keep peanut brittle crispy? ›

The candy will attract moisture from the air, making it unpleasantly sticky instead of shatteringly crisp. Once it's completely cool, transfer it to an airtight container.

Why is my peanut brittle hard but sticky? ›

What's important to know is that the corn syrup controls the grain of the brittle so adding too little and you have a grainy textured brittle, while adding too much will result in a stringy and sticky brittle.

Can you overcook peanut brittle? ›

Use a candy thermometer!

If you overcook the brittle, it could be bitter or burnt. If you undercook it, the brittle won't properly set and the end result will be sticky.

Why is my peanut brittle not airy? ›

Working quickly, pour into prepared 10×15 pan. To keep the brittle light and airy, do not spread or flatten the mixture. Instead, let it flow freely. Place in a cool area and leave until completely cooled, about 2-3 hours.

Can you use parchment paper when making peanut brittle? ›

You will want the cookie sheet to be non-stick. Use parchment paper, a silicone baking sheet or a greased cookie sheet. Spread the peanut brittle as thin as you can. Immediately add your sea salt.

How long does homemade peanut brittle last? ›

To store: Once it's completely cooled, store peanut brittle 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.

How bad for you is peanut brittle? ›

Outside of that single ingredient, peanut brittle is painfully unhealthy. It contains: sugar, corn syrup, and butter, all of which are unhealthy for your body in different ways. But, peanut brittle becomes terrible for your teeth once all of those ingredients are combined into the final product.

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 is the best pan for making peanut brittle? ›

Heavy 6 quart Dutch Oven pot. Mine is an old 1970's Club Aluminum. It's perfect! You need a heavy THICK pot so it won't scorch.

How do you fix peanut brittle that's too soft? ›

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.

What makes brittle hard? ›

What Makes it Brittle? The sugar will be cooked to 300ºF (149ºC)—hard crack stage; which when set up would be hard like a lollipop. But peanut brittle is delicate and you can easily bite into it—how? The secret is in the baking soda.

How long does it take for brittle to harden? ›

Don't try to spread the candy once it's on the baking sheet as it starts hardening almost immediately and spreading it doesn't work well. Let the peanut brittle cool for 30 minutes, then break it into pieces. Store it in an airtight container at room temperature for up to two months.

Is peanut brittle supposed to be hard? ›

Peanut Brittle is a smooth, flat candy (similar to toffee), with peanuts in it, that is cooked on the stovetop and poured onto a sheet pan to cool. Once it cools it's broken into small individual-size pieces of hard candy and lasts at room temperature for several weeks.
