Classic Old Fashioned Peanut Brittle is a crunchy, sweet treat made with caramelized sugar, buttery peanuts, and a touch of vanilla. This timeless confection combines a perfect balance of sweetness and nutty flavor, finished with a delicate crunch from the baking soda infusion. Perfect for holiday gifts or anytime snacking.

Ingredients

Sweet Base

  • 2 cups granulated sugar
  • 1 cup water
  • 1 cup light corn syrup

Peanuts and Flavorings

  • 2 cups peanuts (see note below)
  • ½ teaspoon salt (only add this if using unsalted peanuts)
  • 2 tablespoons butter
  • 1 teaspoon vanilla extract
  • 1 teaspoon baking soda

Instructions

  1. Prepare the Baking Sheet: Line a baking sheet with parchment paper or a silicone baking mat to prevent sticking and facilitate easy removal of the brittle once cooled.
  2. Combine Sugar Mixture: In a large saucepan, pour in the granulated sugar, water, and corn syrup. Place the saucepan over medium heat and stir occasionally as the mixture heats.
  3. Cook to Soft Ball Stage: Continue cooking and occasionally stirring the mixture until it reaches 245°F, known as the soft ball stage. This process usually takes a little over 20 minutes on a medium gas stove. Be sure to use a candy thermometer for accuracy.
  4. Add Peanuts and Butter: Stir in the peanuts, salt (only if peanuts are unsalted), and butter. Keep cooking the mixture over medium heat while stirring occasionally, watching carefully as it approaches a higher temperature.
  5. Cook to Hard Crack Stage: Continue heating until the mixture reaches 300°F, the hard crack stage, which takes about 8–9 more minutes. This step is critical as the brittle’s characteristic crunch develops here. Monitor closely to avoid burning.
  6. Remove From Heat and Add Flavorings: Once at 300°F, remove the pan from heat immediately. Carefully stir in the vanilla extract and baking soda. The mixture will bubble up and foam due to the baking soda; this creates a light, airy texture in the brittle.
  7. Spread the Brittle: Quickly pour the foamy mixture onto the prepared baking sheet. Use a butter knife, spoon, or offset spatula to spread the brittle evenly into a thin layer before it sets.
  8. Cool and Break: Allow the brittle to cool completely for about one hour at room temperature. Once hardened, break it into pieces for serving or storage.

Notes

  • For best results, use fresh, raw or roasted peanuts according to your preference. If using salted peanuts, omit the added salt to avoid oversalting.
  • Use a reliable candy thermometer to ensure accurate temperature readings for perfect brittle texture.
  • Be cautious during the cooking and pouring stages, as the sugar mixture is extremely hot and can cause burns.
  • Store peanut brittle in an airtight container at room temperature for up to two weeks to maintain freshness and crunch.
