Peanut brittle is made by coating peanuts in cooked sugar syrup that cools into a hard, crisp sheet. Some recipes add baking soda to create a lighter, more porous texture, while others use only peanuts and caramelized sugar.
To make peanut brittle, stir roasted peanuts into sugar syrup cooked until caramel-colored, then spread the mixture thinly on a lined tray. Let it cool completely before breaking it into pieces; hot sugar can cause severe burns.
Peanut brittle is usually chewy because the sugar syrup was not cooked enough or the candy absorbed moisture after cooling. Cook the syrup until properly caramelized, spread it thinly, and store the cooled brittle in an airtight container in a dry place.
Keep peanut brittle in an airtight container in a cool, dry place, away from steam and humidity. Moisture makes the sugar coating sticky and soft; avoid refrigerating it, since condensation can also spoil its crisp texture.
Yes, you can freeze peanut brittle in an airtight, freezer-safe container. Keep it sealed while it comes back to room temperature so condensation does not make the sugar coating sticky.
Baking soda releases gas in the hot sugar mixture, creating tiny bubbles that make peanut brittle lighter and easier to bite. It is optional: omitting it gives a denser, harder candy.
Peanut brittle may fail to harden if the sugar syrup was removed from the heat too early or the candy cooled in a humid place. Cook the syrup until it reaches a deep caramel color, spread it thinly, and let it cool somewhere dry.
Stored in a tightly sealed container in a cool, dry place, peanut brittle can stay crisp for several weeks. Discard it if it develops an unusual smell, taste, or visible mold, and keep it away from humid conditions.
No, peanut brittle is generally thinner and more brittle than peanut toffee. Brittle recipes commonly use caramelized sugar, while toffee often includes butter and has a richer, denser texture; recipes vary.
Peanut brittle contains a concentrated sugar coating and can raise blood glucose; the peanuts do not cancel that effect. People with diabetes should account for it in their individual meal plan and ask their healthcare professional if they need personalized guidance.

Peanut brittle is a hard, crisp confection made by coating roasted peanuts in cooked sugar syrup, then cooling the mixture until it sets and breaking it into pieces. It is a familiar homemade sweet as well as a popular treat from confectioners and shops.
The peanuts bring a toasted, savoury note to the intense sweetness, while the texture is glassy and crunchy. It is often enjoyed as a small snack or shared after a meal; in many places, it also appears around holidays and celebrations. Peanut brittle is sugar-rich and energy-dense, with some protein and fibre from the nuts. A small piece alongside fresh fruit or unsweetened tea makes for a less heavy treat.
