ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

granulated sugar
light corn syrup
water
unsalted butter
roasted unsalted peanuts
baking soda
vanilla extract
salt (optional, if using unsalted peanuts)

directions

Line a large baking sheet with parchment paper or a silicone baking mat and set aside.

In a heavy-bottomed saucepan over medium heat, combine the sugar, corn syrup, and water. Stir until the sugar dissolves.

Increase heat to medium-high and bring to a boil without stirring. Cook until the mixture reaches 300°F (150°C) on a candy thermometer (the hard crack stage).

Remove from heat and immediately stir in the butter, peanuts, baking soda, vanilla extract, and salt if using. The mixture will foam up—stir quickly to combine.

Immediately pour the brittle onto the prepared baking sheet and use a spatula to spread it out as thinly as possible.

Allow the peanut brittle to cool completely at room temperature, then break it into pieces.
