1-Getting started: Getting started with peanut brittle is as simple as lining a sheet pan with parchment paper to avoid any sticking mishaps. Begin by preparing your peanuts, butter, baking soda, and vanilla extract so everything is ready when you need it. In a medium saucepan, mix 2 cups sugar and 1/2 cup water, stirring well before adding 1 cup corn syrup.

2-Cooking: Cook this over medium heat, stirring occasionally, until it reaches a gentle boil. Once boiling, attach a candy thermometer to the saucepan, making sure it’s submerged but not touching the bottom. Keep cooking and stirring occasionally until the temperature hits 250°F, then add 2 cups salted roasted peanuts and stir constantly until it reaches 300°F.

3-Detailed Steps for Success: At 300°F, remove the pan from heat and quickly stir in 2 tablespoons butter, 1 1/2 teaspoons baking soda, and 1 1/2 teaspoons vanilla extract; watch as the mixture foams up for that perfect crunch. Carefully pour the hot mix onto your prepared pan and spread it out evenly with a knife or spoon. Let it cool for at least 30 minutes before breaking it into pieces for serving or storage.
