Make the best homemade peanut brittle with this easy recipe! Crunchy, buttery, and full of roasted peanuts, this classic candy is perfect for holidays, gifts, or satisfying your sweet tooth anytime.
Line a rimmed baking sheet with a silicon baking mat or parchment paper and set aside. Have a small dish of water prepared along with a silicon brush.
Rub a thin coat of vegetable oil along the inside of your saucepan and clip a candy thermometer to the side. Add sugar, water and salt to the saucepan and bring to a boil over medium heat, stirring occasionally.
Stirring occasionally cook the sugar mixture until the temperature reaches 280 ℉. If the sugar begins to crystalize brush down the sides of the pan with water using a silicon brush.
Add in the peanuts and cook until the thermometer reaches 300℉, stirring frequently.
Once the temperature has reached 300 ℉ remove the pan from the heat and stir in the vanilla and baking soda. Once you add the baking soda the brittle will quickly bubble up and aerate, this is normal.
Remove the thermometer from the pan and pour the brittle mixture into the baking pan. Spread the peanut mixture out with a silicon spatula and set the pan aside to let the brittle harden (about 30 minutes).
Break apart the brittle into chunks. Store in an airtight container with parchment paper in between layers for up to 1 week.
