Ingredients
  

  • Butter for the silicone mat or baking sheet and spatula
  • 2 cups granulated sugar
  • ½ cup unsalted butter
  • ⅓ cup water
  • ½ cup light corn syrup
  • 1 tsp baking soda
  • 1 tsp vanilla extract
  • 2 ½ cups salted roasted peanuts, (about 12 ounces)
  • Flaky sea salt (optional), for finishing

Recommended Equipment

Instructions

  • Butter a silicone mat or large nonstick baking sheet and lightly butter a spatula. Set aside.
    Butter for the silicone mat or baking sheet and spatula
    • Have the buttered mat or baking sheet and buttered spatula ready before the brittle reaches 300°F, since it sets quickly once the peanuts are stirred in.
  • In a large, deep saucepan with a candy thermometer attached, combine the sugar, butter, water, and corn syrup. Cook over medium-high heat, stirring gently until the sugar dissolves, then cook without stirring to 300°F.
    2 cups granulated sugar | 1/2 cup unsalted butter | 1/3 cup water | 1/2 cup light corn syrup
  • Remove the pan from the heat and immediately stir in the baking soda and vanilla extract—it will bubble up a bit. Stir in the peanuts, then quickly scrape the mixture onto the buttered silicone mat or baking sheet. Use the lightly buttered spatula to spread it into a thin, uniform layer. While the brittle is still tacky, sprinkle with some flaky sea salt, if desired. Let it cool completely before breaking up and storing.

    • Warming the peanuts beforehand will prevent the brittle from hardening as quickly.
