  • 2 cups granulated sugar
  • 1 cup light corn syrup
  • 1/2 cup water
  • 1/4 teaspoon salt
  • 1 cup butter cut into ½-inch thick slices
  • 2 1/4 cups dry roasted peanuts unsalted
  • 1 teaspoon baking soda


  • Line a large sheet pan with parchment paper or a nonstick baking mat; set aside.
  • In a large pot, add the sugar, corn syrup, water, and salt. Attach a candy thermometer to the side of the pot. Cook over medium heat, stirring constantly, until sugar is dissolved, and the mixture comes to a boil.
  • Once the mixture is boiling, very carefully add the butter to the pot. Continue to cook, stirring often, until a candy thermometer registers 280F degrees, which should take about 15 minutes.
  • Add the peanuts to the candy mixture and cook for an additional 10 minutes, stirring very frequently, until a candy thermometer registers 305F degrees. Remove the pot from the heat and stir in the baking soda.
  • Pour the peanut brittle evenly onto the prepared sheet pan. Spread out to about 1/4-inch thickness. Cool completely to room temperature, then break into pieces.
