Instructions

    Cup of Yum
  1. Line a large baking sheet with a silicone baking mat or parchment paper. Set aside.
  2. Since this recipe moves quickly, I recommend you measure out and organize your ingredients before you start the cooking process.
  3. In a heavy 2-quart saucepan, over medium heat, bring to a boil sugar, corn syrup, salt, and water. Stir until sugar is dissolved.
  4. Add in peanuts and stir until combined.
  5. Place a candy thermometer into the mixture and continue cooking, stirring  frequently until temperature reaches 300°F.
  6. Immediately remove saucepan from heat and quickly stir in butter, vanilla, and baking soda.
  7. Immediately pour the mixture onto the prepared baking sheet. Using a rubber spatula, spread the mixture into a rectangle about 14x12 inches.
  8. Cool completely at room temperature.
  9. Snap candy into pieces and store in an airtight container at room temperature.
