How To Make Peanut Brittle

Roasted peanuts are slathered with sweet and buttery syrup to make a peanut brittle that’s crispy and satisfyingly sweet.

Preparation: 10 minutes
Cooking: 35 minutes
Total: 45 minutes



  • 2cupsgranulated sugar
  • 1cuplight corn syrup
  • ¼tspsalt
  • ½cupwater
  • 1cupbuttercut into slices
  • 2 ¼cupsdry roasted peanutsunsalted
  • 1tspbaking soda


  1. Line a sheet pan with parchment paper or a nonstick baking mat.

  2. Place the sugar, corn syrup, salt and water in a large, deep pan. Clip a candy thermometer to the side of the pan.

  3. Cook over medium heat, stirring constantly until sugar is dissolved and the mixture comes to a boil. This takes about 6 to 7 minutes.

  4. Add the butter to the pan. Continue to cook, stirring occasionally, until a candy thermometer registers 280 degrees F. This takes about 15 minutes.

  5. Add the peanuts to the pot and cook for an additional 10 minutes, stirring constantly, or until a candy thermometer registers 305 degrees F.

  6. Remove the pot from the heat and stir in the baking soda.

  7. Pour the peanut mixture evenly onto the sheet pans. Spread to a ¼ inch layer.

  8. Cool, then break into pieces and serve.
