  • 1 cup dark brown sugar
  • 1 cup granulated sugar
  • 1 cup corn syrup
  • 1/2 teaspoon salt
  • 1/2 cup water
  • 4 tablespoons unsalted butter softened to room temperature
  • 2 teaspoons vanilla extract
  • 2 teaspoons baking soda
  • 3 cups lightly salted dry roasted peanuts


  • Preheat oven to lowest temperature possible and generously grease a rimmed baking sheet with cooking spray.
  • Place baking sheet to warm in the oven while you make your brittle.
  • Heat a small metal saucepan over low heat - keep this warm while you make the brittle, you will use this to help press out the brittle.
  • In a medium sized saucepan, place brown sugar, granulated sugar, corn syrup, salt, and water.
  • Attach a candy thermometer to the side of the pan, then over medium heat, bring the mixture to 300 degrees F stirring frequently (this takes about 30 minutes). 

  • Remove from heat and quickly stir in butter, vanilla, baking soda, then peanuts.
  • Immediately pour the brittle onto the warm prepared baking sheet.
  • Grease the bottom of the warmed small metal saucepan generously with cooking spray, then carefully press out the mixture to 1/4 inch - 1/2 inch thick (the brittle, sheet pan, and saucepan are VERY hot).
  • Let cool slightly at room temperature.
  • Clean the dirty saucepans and candy thermometer immediately with hot water and soap, so the brittle doesn't solidify.
  • Place the brittle in the freezer to cool completely.
  • Snap into pieces, place into an airtight container, then store in the freezer.
  • Enjoy frozen, let chill in the fridge, or enjoy at room temperature.
