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!

    After I added the peanuts the temperature dropped 10 degrees and it was very hard to stir. When I added the peanuts the temperature was 280. Then it dropped and was very hard to stir but I persisted stirring until combined. I removed from heat and added the the baking soda then plopped small sizes of the mix onto the parchment paper. It seemed to be ok as I noticed it harded up on the spoon and thermometer. I added cinnamon and ginger to the peanut before mixing into the syrup and sprinkled coconut onto the parchment paper before popping the mix onto the parchment. I hope it tastes good.
