Ingredients

Scale

Base and Toppings

  • 1 cup butter
  • 1 cup sugar
  • 1 teaspoon pure vanilla extract
  • 2¼ cups roasted sea salt peanuts (divided: 2 cups for base, ¼ cup chopped for topping)
  • 1 bag (approximately 12 oz) semi-sweet chocolate chips

Instructions

  1. Prepare the Pan and Peanuts: Line a 9×13-inch cake pan with parchment paper. Spread 2 cups of roasted sea salt peanuts into an even layer to form the brittle base.
  2. Melt Butter and Mix Ingredients: In a medium-sized pan over medium heat, combine 1 cup butter, 1 cup sugar, and 1 teaspoon pure vanilla extract. Stir continuously until the butter melts completely.
  3. Simmer the Toffee Mixture: Allow the mixture to come to a simmer and cook for 7 to 8 minutes, stirring occasionally. Monitor closely to prevent burning. The mixture will gradually darken and start separating slightly.
  4. Check the Candy Stage: When the toffee mixture reaches a caramel color and flows from the spoon in a ribbon-like manner, immediately pour it evenly over the layered peanuts in the cake pan.
  5. Spread the Toffee Layer: Use an offset spatula to spread the caramel mixture evenly over the peanuts, ensuring full coverage.
  6. Add Chocolate Chips: Pour the entire bag of semi-sweet chocolate chips over the hot toffee layer. Let sit undisturbed for 2 to 3 minutes to allow the chocolate to melt thoroughly.
  7. Spread Melted Chocolate: Using an offset spatula, spread the melted chocolate evenly over the toffee until smooth.
  8. Top with Chopped Peanuts: Chop the remaining ¼ cup of roasted sea salt peanuts and sprinkle them evenly over the melted chocolate as a crunchy garnish.
  9. Cool and Set: Let the brittle sit at room temperature for about 2 hours to set, then place it in the refrigerator until firm and ready to enjoy. Break into pieces before serving.

Notes

  • Use an offset spatula to easily spread hot caramel and melted chocolate evenly.
  • Watch the toffee mixture carefully during simmering to avoid burning, which can impart bitterness.
  • Line your pan with parchment paper for easy removal and cleanup.
  • Store the brittle in an airtight container at room temperature for up to two weeks.
  • For a nut-free version, substitute peanuts with toasted seeds such as pumpkin or sunflower seeds.
