Ingredients

1 cup granulated sugar

1/2 cup light corn syrup

1/4 cup water

1/4 teaspoon salt

1 cup roasted, unsalted peanuts

2 tablespoons unsalted butter, softened

1 teaspoon vanilla extract

1 teaspoon baking soda


Instructions

  1. Prepare the Workspace
    • Grease a large baking sheet or line with parchment paper. Set aside.
  2. Cook the Syrup
    • Combine sugar, corn syrup, water, and salt in a medium saucepan.
    • Stir over medium heat until sugar dissolves.
    • Increase heat to medium-high; boil without stirring until the mixture reaches 300°F (hard crack stage) using a candy thermometer.
  3. Add Peanuts
    • Stir peanuts into the hot syrup and cook for 1-2 minutes, ensuring even coating.
  4. Incorporate Butter and Vanilla
    • Remove from heat; mix in butter and vanilla carefully.
  5. Add Baking Soda
    • Stir in baking soda, allowing the mixture to foam and create a light texture.
  6. Spread the Brittle
    • Pour onto the prepared baking sheet. Spread thinly and evenly using a spatula or spoon.
  7. Cool and Break
    • Allow the brittle to cool completely. Break into pieces and store in an airtight container.

Notes

Use a candy thermometer for precise results.

Ensure the brittle mixture reaches 300°F for the perfect crunch.

Spread the mixture quickly, as it hardens as it cools.
