Homemade Peanut Brittle
📝 Ingredients (Makes about 1½ pounds)

  • 2 cups granulated sugar
  • 1 cup light corn syrup
  • ½ cup water
  • 1½ cups roasted, unsalted peanuts
  • 2 tablespoons unsalted butter

👨‍🍳 Instructions

1️⃣ Prepare Your Station:
📄 Line a baking sheet with parchment paper or lightly butter it. Have all ingredients measured and ready—this recipe moves fast once the sugar caramelizes.

2️⃣ Cook the Sugar Mixture:
🍯 In a heavy-bottomed saucepan over medium heat, combine sugar, corn syrup, and water. Stir until sugar dissolves, then bring to a boil without stirring. Continue boiling until the mixture reaches 300°F (hard crack stage) on a candy thermometer.

3️⃣ Add Butter and Peanuts:
🥜 Stir in the butter and peanuts. Cook for 1–2 more minutes, stirring constantly, until golden brown.

4️⃣ Add Vanilla and Baking Soda:
✨ Remove from heat and quickly stir in baking soda and vanilla. The mixture will foam up—stir fast!
