  • 2 cups granulated sugar
  • 1 cup light corn syrup
  • 1 cup water
  • 2 1/2 cups raw Spanish peanuts
  • 1/2 tsp salt
  • 1 tsp baking soda
  • 1 tbsp unsalted butter
  • 1 1/2 tsp vanilla extract


  • In a large saucepan, combine the sugar, corn syrup and water. Cook over medium heat until the sugar dissolves, stirring constantly.
  • Once sugar dissolves, increase the heat to medium-high. Add peanuts and salt then cook until the temperature reaches 300 degrees or the hard crack stage, making sure to continuously stir.
  • Finally add in baking soda, butter and vanilla and mix well. Next, pour the brittle mixture onto 2 thoroughly greased baking sheets and spread to the thickness you desire.
  • Once completely cooled, crack into pieces and serve.


If stored in an airtight container at room temperature, homemade peanut brittle will stay fresh for 6-8 weeks. Do not refrigerate or the cool moisture will cause the brittle to soften.
