Ingredients You’ll Need

Here are a few notes on the key ingredients for this peanut brittle:

  • Corn syrup: Corn syrup sweetens the brittle, adds shine, and gives it a delicious texture. 
  • Baking soda: Baking soda helps create all the little air bubbles in peanut brittle, giving it a perfect crunchy texture.
  • Butter: Butter adds a bit of richness and delicious flavor to the brittle. Salted butter adds more depth of flavor than unsalted butter!
  • Peanuts: We can’t make this recipe without peanuts! I like using roasted, unsalted peanuts. We’re already adding salt to the brittle, and roasted nuts have a bit more flavor and better texture than raw peanuts. 
  • Salt/Vanilla: I love adding a hint of pure vanilla extract and a sprinkle of Kosher sea salt to my brittle recipe. Real vanilla extract enhances the buttery, caramel flavor of the brittle.

How to Make Peanut Brittle

  • Line a rimmed baking sheet with parchment paper or foil and spray it lightly with nonstick cooking spray. 
  • Gather all of your ingredients and measure them into bowls before starting. 
  • Add the granulated sugar, light corn syrup, and water to a large, heavy-bottomed saucepan set over medium heat. 
  • Cook, stirring occasionally, until the mixture begins to boil. Cook the mixture until it reaches 270F on a candy thermometer and is golden brown in color. Be patient– this should take about 6-8 minutes.

  • Next add the peanuts and cook the candy until it reaches exactly 300F. This should take another 8-10 minutes. 
  • Quickly remove the candy mixture from the heat and stir in the butter, baking soda, salt, and vanilla. 
  • Pour the brittle mixture onto the prepared baking sheet and spread it into an even layer. 
  • Let the brittle cool at room temperature for 1 hour, or until it has reached the hard crack stage. Then break it into large pieces and enjoy. Garnish with a sprinkle of flakey sea salt, if desired. 

Storage Instructions

Store any leftover brittle in an airtight container at room temperature for up to one week.

FAQs

What is peanut brittle made of?

Peanut brittle is made from a sugar mixture that includes corn syrup, butter, and a few other ingredients like baking soda, water, and salt. These ingredients are boiled over the stovetop in a heavy-bottomed pan, and then spread over peanuts on a rimmed baking sheet. Once the mixture cools, it has a deliciously crispy and buttery texture.

What country is peanut brittle from?

Peanut brittle most likely originated in Europe, where the Celts made a similar bark by baking sugar and peanut butter. Irish settlers brought the candy to America in the 1830s, where it became especially popular in the South. Today, most Americans associate this classic candy with the holiday season.

Why do you put baking soda in peanut brittle?

Baking soda adds air bubbles to candy brittle, which gives it the “brittle” texture. It’s added after the sugar and corn syrup mixture is removed from the heat, along with butter, vanilla, and salt. Once the brittle cools, it has the perfect light, crispy texture that this candy is known for.
