Why this recipe is the best:

Homemade peanut brittle is actually very easy to make. There are a lot of recipes out there for microwave brittle, however I find this stove top recipe to be the best option because of how perfect it turns out every time.

  • Only five ingredients needed. Not counting water, of course.
  • It’s quick and easy to make. Peanut brittle made on the stove only takes about 10 minutes.
  • The taste and the crunch are unreal. The sweet buttery toffee crunch will melt in your mouth. The salted dry roasted peanuts are the perfect addition to the sweet brittle.
  • It makes a great gift! Add it to the various cookies, fudge, and other treats you make during the holidays.

Ingredients needed to make this recipe:

  • Sugar: I use organic granulated sugar which is why it is not super white in the photo below.
  • Water: This is used any time you boil sugar and corn syrup together to make treats like caramel and brittle. It evaporates as the mixture boils.
  • Butter: I use unsalted butter since the peanuts are salted and I sprinkle salt on top.
  • Lite Corn Syrup: Do not use dark corn syrup for this recipe. I use Karo brand.
  • Baking soda
  • Dry Roasted Peanuts: I get mine at Trader Joe’s. I find the dry roasted salted peanuts give the best taste and texture.
  • Sea Salt Flakes: These not only are fantastic against all that sugar, but they are gorgeous.

Equipment needed:

  • Saucepan: I use an All-Clad 3 quart saucepan
  • Thermometer: You must use an accurate thermometer to get your brittle to the exact temperature
  • Spatula: You’ll need a high heat resistant silicone spatula. Alternatively, you can use a wooden spoon to stir the peanut brittle while it’s boiling, but I like the spatula because it can easily scrape all the brittle out of the pan.
  • Parchment paper: To pour the hot brittle onto

How to make Peanut Brittle:

  1. Cook the sugar mixture: You’ll combine the sugar, water, corn syrup, and butter in your pan on the stove. You’ll want to maintain a heat that is high enough to maintain a bubbling boil. This mixture will be cooked until it reaches 300°F.
  2. Add baking soda: As soon as it hits temperature, you will remove it from the heat and add the baking soda. You will instantly see the brittle change in color and texture.
  3. Add peanuts: Quickly stir in the peanuts.
  4. Pour: Then pour the brittle onto parchment paper.
  5. Spread: Using your spatula, spread the peanut brittle into an even layer.
  6. Break: After the brittle has cooled for at least 30 minutes, you can break it into pieces.

Recipe tips for the best results:

  • Measure ingredients ahead of time: Make sure you have the baking soda and peanuts pre-measured and the parchment paper set out. Once you remove the brittle from the heat, it will start to set quickly.
  • Cooking temperature: You must cook the brittle to the correct temperature of 300°F. This is the “hard crack” stage. Any less and it will be chewy, and anything past 310°F risks taking it too far and possibly burning.
  • Be careful: Don’t taste it until it has cooled. You can trust me on this one. Sugar boils at a much higher temperature than water so you can easily burn your skin badly. Also, if you eat this peanut brittle before it has cooled, you’ll find that it will completely stick to your teeth.

Making Homemade Peanut Brittle is easy! This simple stove top recipe is easy to follow and the brittle turns out perfect every time.

Ingredients 

  • 2 cups sugar

  • 1/2 teaspoon baking soda
  • 1 1/2 cups dry roasted peanuts about 8 ounces

    I love peanut brittle, but I have never actually made it before. It was unbelievably easy and it came out perfect. I ended up making a second batch because I ate half of the first batch. Definitely a keeper recipe. Thank you.
