Description

Mom’s Best Peanut Brittle is a classic, crunchy candy featuring roasted peanuts embedded in a rich, buttery caramelized sugar base. This easy-to-make recipe combines simple pantry ingredients to create a nostalgic and satisfying treat perfect for gifting or snacking.


Ingredients

Scale

For the Peanut Brittle

  • 1 cup white sugar
  • ½ cup light corn syrup
  • ¼ cup water
  • ¼ teaspoon salt
  • 1 cup peanuts
  • 2 tablespoons unsalted butter
  • 1 teaspoon baking soda


Instructions

  1. Prepare Baking Sheet: Grease a large rimmed baking sheet or line it with a silicone baking mat to prevent sticking. Set aside.
  2. Combine Ingredients: In a heavy 2-quart saucepan over medium heat, combine the sugar, light corn syrup, water, and salt. Stir continuously until the sugar is fully dissolved and the mixture starts boiling, approximately 5 minutes.
  3. Add Peanuts and Cook: Stir in the peanuts. Attach a candy thermometer and continue cooking, stirring occasionally but not excessively to avoid grainy brittle, until the mixture reaches 300 to 310°F (150 to 155°C) – the hard crack stage, about 10 minutes.
  4. Mix Butter and Baking Soda: Remove the saucepan from heat. Quickly stir in the unsalted butter and baking soda; the soda will cause the mixture to foam and become airy.
  5. Spread the Mixture: Immediately pour the hot mixture onto the prepared baking sheet. Using two forks, lift and pull the brittle into a 12×14-inch rectangle while still hot.
  6. Cool: Allow the peanut brittle to cool completely until firm, at least 30 minutes.
  7. Break into Pieces: Once cooled, use a mallet or your hands to break the brittle into bite-sized pieces.
  8. Serve and Store: Enjoy immediately or store in an airtight container for freshness.

Notes

  • You can substitute the peanuts with macadamia nuts for a special variation and gift option.
  • Using a silicone baking mat instead of greasing the baking sheet helps prevent sticking and simplifies cleanup.
  • Be cautious during cooking; reaching the correct temperature is critical to achieve the perfect brittle texture.
  • Avoid excessive stirring after adding peanuts to prevent graininess in the brittle.
  • Store peanut brittle in an airtight container in a cool, dry place to maintain crispness.
