Peanut Brittle Recipe (1)

My family loves it when I break out the peanut brittle. It’s one of our favorite foolproof holiday treats (like pumpkin brownies and pecan pie brownies) that’s perfect for family gatherings and parties.

This peanut brittle is crunchy, sweet, and has a satisfying buttery flavor. Plus, since there’s no corn syrup, I don’t have to feel guilty for sharing it with my family and friends.

Both kids and adults can’t get enough of this brittle. It’s always gone before I know it, so I usually make a double batch, just so I’m guaranteed to get a piece!

Why this recipe works

  • 3 ingredients. That’s right, just 3 ingredients are all you’ll need, and you likely have all of them on hand already.
  • Healthier alternative. Like my peanut butter Rice Krispie Treats, this peanut brittle is free of corn syrup, though it’s still crunchy and sweet, so no one will even notice.
  • Easy to make ahead. Like Turkish delight, peanut brittle is easy to make in advance and store until you need it, making it a convenient treat. It’s also a fabulous edible gift.
  • Perfect texture and flavor. This recipe makes sweet and savory peanut brittle with a signature snap and the perfect amount of crunch.

What I love most about this recipe is how nostalgic it is. Like my 3-ingredient chocolate fudge, this peanut brittle is sure to bring back fond memories for everyone you share it with!

Ingredients needed

Like I mentioned earlier, this recipe calls for only three ingredients, including the star of the show: peanuts! Here is what you’ll need:

  • Sugar. Either white, raw, or brown sugar will work. Just keep in mind brown sugar has a strong molasses flavor to it.
  • Butter. I prefer unsalted butter, so it’s sweeter than salty.But of you like a little sweet and salty combination, use salted butter.
  • Chopped peanuts. Opt for dry roasted peanuts.
  • Salt. If you didn’t use salted peanuts or salted butter, add a touch of salt.

How to make peanut brittle

Step 1- Prep work: Line a baking sheet with parchment paper.

Step 2- Melt the sugar: Add sugar to a large saucepan or skillet over medium heat. Let the sugar melt while stirring occasionally with a wooden spoon. Continue doing this until it turns into a thick caramel syrup.

Step 3- Add butter and peanuts: Once the sugar has completely melted, add the butter and mix until fully incorporated and the candy reaches a hard crack stage. Stir in the peanuts.

Step 4- Shape the brittle: Transfer the brittle mixture onto the prepared baking sheet and spread it into an even thin layer using a rubber spatula.

Step 5- Refrigerate and serve: Store the brittle in the refrigerator for at least an hour to firm up. Then, break it apart into bite-sized pieces and enjoy!

Recipe tips and variations

  • Use a candy thermometer. This is my #1 tip to prevent the sugar burning. Your sugar and butter mixture should be transferred to the baking sheet when it reaches 300F (most thermometers have an option for a ‘hard crack’).
  • Don’t freeze until the brittle cools. Otherwise, it will get too firm and be hard to eat. Your patience will be rewarded!
  • Don’t let the sugar boil. If the sugar boils before all the crystals have melted, the sugar will crystalize, and you’ll have to start over.Again, candy thermometer!!
  • Make extra crunchy brittle. Add one teaspoon of baking soda at the end of the cooking process. It creates little air bubbles in the brittle, adding even more crunch to every bite.
  • Add vanilla extract. One teaspoon should add the perfect amount of vanilla flavor if that’s what you’re looking for.
  • Swap the peanuts. If you’re not a fan of peanuts or have an allergy, you can make this exact recipe with almonds, walnuts, pecans, cashews, macadamia nuts, hazelnuts, or a combination of nuts.
  • Make it vegan. Simply swap the butter for a vegan alternative.

Storage instructions

To store: Peanut brittle should be stored at room temperature in an airtight container for up to 6-8 weeks. Refrigerating the brittle could cause it to soften.

To freeze: If you’re planning on freezing the brittle, don’t break it up into chunks, otherwise, the pieces will stick to each other. Instead, store it in large sheets with parchment paper in between. Stored in a freezer-safe container, it should be kept for up to 6 months. Allow it to thaw overnight in the fridge before eating.

Frequently asked questions

Why is my peanut brittle not crunchy?

Your peanut brittle may not be crunchy if it wasn’t cooked for long enough to reach 300F. Having a candy thermometer can help ensure the brittle mixture reaches the right temperature to get that signature crack.

What does baking soda do to brittle?

Baking soda creates small air bubbles in brittle, giving it a little extra crunchy texture.

Why is my peanut brittle bitter?

If your peanut brittle is bitter, it could be because the sugar got burnt while cooking. If it reaches above 350F, it will likely have a burnt and bitter flavor.

Why is my peanut brittle rubbery? ›

Didn't get it hot enough. You have to hit hard crack stage heat or it's not going to harden. From internet: Hard-Crack Stage is a cooking term meaning that a sugar syrup being heated has reached 149 – 154 C (300 – 310 F.) It is a test of how hot a sugar syrup is, and of how much water is left in it.

What makes brittle hard? ›

Do you cool peanut brittle in the fridge? ›

I recommend placing pieces of wax paper or parchment paper between the candy pieces to keep them from sticking together. I do not recommend placing your brittle in the refrigerator (remember, humidity is the biggest enemy of candy, even after it's done cooking!).

Do you need to refrigerate 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 long does it take for brittle to harden? ›

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.

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.
