Ingredients
  • 2 cups granulated sugar
  • 1 cup corn syrup
  • 1/2 cup water
  • 1/2 teaspoon salt
  • 1/2 cup butter, cubed
  • 2 1/2 cups unsalted, roasted peanuts
  • 1 tablespoon vanilla
  • 1 teaspoon baking soda
Instructions
  1. Line a baking sheet with parchment paper or a silpat mat, or butter it well.

  2. In a large, heavy bottomed pan, combine the sugar, corn syrup, water, and salt and bring to a boil over medium heat, stirring occasionally.  Continue to cook, stirring frequently until the temperature reaches 280 degrees F on a candy thermometer.

  3. Add the butter and peanuts and continue to cook, stirring constantly another 7-10 minutes until the temperature reaches 300 degrees F.  

  4. When the candy reaches 300 degrees F, immediately remove from heat and add the baking soda and vanilla, stirring vigorously to combine.

  5. Immediately pour the hot brittle mixture onto the prepared baking sheet, then tilt and jiggle the sheet to help it spread covering the entire pan from corner to corner.  

  6. Let the peanut brittle set until completely hard, then use a mallet or back of a spoon to crack the brittle into chunks or bite-size pieces.  Store in an airtight container for up to 1 week.

Recipe Notes

If using salted peanuts, omit the salt in the recipe.
