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!

Peanut Brittle Ingredients

To make peanut brittle you will need sugar, light corn syrup, salt, water, butter, unsalted peanuts and baking soda.

Ingredients including butter, corn syrup and sugar.

How Do You Make Peanut Brittle?

To make this peanut brittle recipe start by lining a sheet pan with parchment paper or a baking mat. Next, place sugar, corn syrup, water and salt in a large pot. Bring the mixture to a boil while stirring constantly. Be sure to clip a candy thermometer to the side of the pot so you can monitor the temperature. After the sugar mixture starts boiling, add butter and cook until the candy reaches 280 degrees F, stirring occasionally. Next, add the peanuts and cook the candy until the thermometer reads 305 degrees F, stirring constantly. Remove the pot from the heat, then stir in the baking soda. Carefully pour the candy mixture onto a sheet pan, and spread it into a thin layer. Let the brittle cool completely, then break it into pieces and serve.

Tips For The Perfect Peanut Brittle

  • 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.
  • 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.
  • Make sure your sheet pan has raised edges so that the peanut brittle does not spill.
  • Lightly spread the hot brittle with a spatula.

Quick Tip

The trick to making peanut brittle is to use a candy thermometer. This is a necessary tool for successful candy. Luckily, candy thermometers are inexpensive and widely available.

Recipe FAQs

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!

Why is my homemade peanut brittle chewy?

If your brittle comes out soft, it means it was not cooked to the proper temperature. It is extremely important to use a candy thermometer. You can make sure that your candy thermometer is accurate by placing it in a pot of boiling water, and it will read 212 degrees F if it’s working properly.

Why is my peanut brittle so hard?

Peanut brittle is a hard candy by nature, but it shouldn’t be so hard that it’s difficult to bite into. The baking soda helps with the texture. It is also important to lightly spread the peanut brittle into the sheet pan, then leave it alone. If you spread it too much, some of the air bubbles will be released and you’ll end up with a harder candy.

How long does peanut brittle last?

Peanut brittle can be stored in an airtight container at room temperature for up to 1 week.

Flavor Variations

While this candy is delicious as-is, you can change up the ingredients to customize the flavors to your tastes.

  • Nuts: Not a fan of peanuts? This recipe will also work well with pecans, almonds, cashews or macadamia nuts.
  • Coconut: Place toasted shredded coconut on your baking sheet and pour the the brittle over the coconut for extra flavor. This works great with macadamia nut brittle.
  • Flavorings: Feel free to stir some spices into your brittle such as cinnamon, nutmeg or ground ginger. I’d use no more than 1/2 teaspoon total for spices. You can also do a sweet and spicy brittle by using ground ancho or chipotle chili powder.
  • Toppings: Make your candy extra special by dipping the cool pieces partway into chocolate. I typically use dark or milk chocolate. You can also add some holiday sprinkles for a festive touch!

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 version I’ve had, and dozens of people ask me for the recipe as soon as they get a taste of this delicious treat!

    I have never even thought about making peanut brittle. Kids bday party was candyland so here we are! It was perfect! Great recipe. Definitely keeping this one.

  2. This is my first time making peanut brittle and this recipe is amazing!! It was super easy to follow and I love the point by point and temp guides included, they were spot on! I thought I had ruined it because I overcooked it but it turned out perfect! After you add the baking soda it looks weird and spreads weird but when it sets its beautiful! I was reading the comments after and realized I had only added one stick of butter instead of 2 (1cup of butter) but it still turned out great!! I’m going to make another batch with the proper amount of butter and I’m positive it will be that much more amazing!

  3. Incredible recipe. I made one batch with butter and another with margarine. The 2 batches turned out well. Thank you for such an easy and accurate recipe.

  4. I’m going to try right now. It looks scrumptious. I’m making it for a friends kids. I’m so excited for them to give me their feedback!!! Thanks Leslie Crowe

  5. 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!

    1. Yes, cook to brittle stage, where a drop into COLD water makes brittle, breakable strings. Works great!

    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.

  7. 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.

  8. 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.

    1. 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.

    2. Are you sure you made it to the brittle stage? It needs to be at the brittle stage or it will turn out like taffy. I use the “drop into cold water” method…when it hits the water and makes brittle strings, it’s ready. I also used about 1/2 tsp more baking sofa to make it easier to crack.

  9. 5 stars
    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.

    1. 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.

      1. 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….
