Old fashioned peanut brittle is a vintage confection made by heating sugar, corn syrup, and water until it reaches the hard crack stage and embedding crunchy peanuts into the mix before cooling it to breakable pieces. This candy has been a staple of holiday cookie trays, gift baskets, and nostalgic kitchens for generations. It’s crunchy, rich with caramelized sugar, and studded with roasted peanuts that balance sweetness with savory depth.

It’s different from soft caramels or chewy toffee the texture should be crisp and shatter with ease. Achieving this classic texture relies largely on precise temperature control and quick work once the sugar reaches the right stage.

What Makes This Version Stand Out

This recipe inspired by Gift of Hospitality offers a well-balanced mix of sweetness and peanut flavor, plus a glossy finish that looks as good as it tastes. The recipe’s foundation uses light corn syrup to prevent sugar crystallization, ensuring a smooth candy surface and consistent texture. The addition of baking soda right at the end introduces tiny air bubbles so the brittle isn’t just hard it’s light and snappy. When you pour it out and watch it set, it’s one of those kitchen moments that makes you feel like a real candy maker.

If you’re gifting this homemade treat, a peanut brittle gift basket turns it into something thoughtful, elegant, and ready to impress.

Step-by-Step Instructions for Old Fashioned Peanut Brittle

Preparing the Sugar Syrup

Line your baking surface: Set up a rimmed baking sheet with parchment or a silicone mat.
Combine sugar, water, & corn syrup: In a large saucepan, mix the granulated sugar with water and corn syrup. Keep heat at medium high heat will risk burning.
Heat to 245°F: Stir occasionally until the sugar dissolves and the mixture reaches around 245°F (soft-ball stage). This takes patience, but slow and steady heat ensures the best structure without graininess.

Adding Peanuts and Mastering Temperature

Stir in peanuts and salt: Add the roasted peanuts (and salt, if needed). Keep stirring as the temperature rises.
Heat to 300°F (hard crack stage): This stage is vital for classic brittle texture. Keep your candy thermometer in the syrup and stir occasionally as the mix deepens in color and edges toward golden caramel.

When the thermometer hits 300°F, you’re just moments away from silky brittle.

Finishing with Flavor and Texture

Remove from heat: Quickly add butter, then vanilla extract, and finally baking soda. The mixture will foam and lighten that’s the baking soda doing its magic to make the candy crisp rather than dense.
Spread and cool: Immediately pour onto your lined baking sheet and spread into a thin, even layer. Once cooled completely (about 60 minutes), break into shards and enjoy.

Once broken, this candy stores beautifully ideal for gifts, trays, or just your personal snack stash.
