Prepare a baking sheet by lining it with parchment paper or generously buttering it to prevent sticking.
In a medium saucepan, combine the granulated sugar, light corn syrup, and water. Stir gently to combine without splashing sugar on the sides of the pan.
Place the saucepan over medium heat and bring the mixture to a boil, stirring until the sugar is dissolved completely.
Once the sugar is dissolved, stop stirring and let the mixture boil. Attach a candy thermometer to the side of the pan, ensuring the bulb is immersed in the syrup but not touching the bottom.
When the mixture reaches 240°F (soft ball stage), add the unsalted butter and raw peanuts. Stir to incorporate and continue cooking, stirring occasionally, until the mixture reaches 300°F (hard crack stage).
As soon as the temperature is reached, remove the saucepan from the heat and quickly stir in the baking soda, vanilla extract, and salt. Be careful as the mixture will bubble and foam up.
Immediately pour the hot mixture onto the prepared baking sheet. Use a spatula to spread it out evenly, working quickly before the mixture sets.
Allow the peanut brittle to cool completely at room temperature, which should take about 30 minutes. Once set, break the brittle into pieces and enjoy.
Store the peanut brittle in an airtight container at room temperature for up to two weeks.
