Ingredients
The secret to perfect peanut brittle lies in the quality and balance of ingredients—too much sugar and it’s tooth-achingly hard; too little and it’s chewy. Stick to these essentials, and you’ll get that signature crisp snap every time.
- Granulated sugar – The backbone of brittle, creating that glass-like texture. Don’t sub with brown sugar (it adds moisture and makes it sticky).
- Light corn syrup – Prevents crystallization for a smooth, glossy finish. Honey *can* work in a pinch, but it’ll darken faster and add a floral note.
- Unsalted butter – Adds richness and keeps the brittle from being brittle (ironically). Salted butter works, but adjust added salt accordingly.
- Raw peanuts – The star! Roasted peanuts burn easily; raw ones toast perfectly in the syrup. For a twist, try cashews or almonds—just keep them raw.
- Baking soda – The game-changer. It aerates the candy, making it lighter and easier to bite. Don’t skip it!
- Vanilla extract (optional) – A splash adds depth, but purists might skip it to let the peanuts shine.
- Flaky sea salt – A finishing sprinkle balances sweetness. Maldon is ideal, but any coarse salt works.
Pro tip: Use a candy thermometer—the difference between 300°F (hard crack stage) and 310°F is burnt bitterness.
And if you’re feeling fancy, a pinch of cinnamon or cayenne can add a subtle kick!
How to Make the Best Crunchy Peanut Brittle Recipe
– Prepare Your Tools and Ingredients: Gather all your ingredients—peanuts, sugar, corn syrup, butter, baking soda, and salt—and measure them accurately.
Line a baking sheet with parchment paper or lightly grease it to prevent sticking. Having everything ready before you start is vital since the cooking process moves quickly.
– Cook the Sugar Mixture: In a heavy-bottomed saucepan, combine sugar, corn syrup, and water. Heat over medium heat, stirring until the sugar dissolves.
Once dissolved, stop stirring and let it boil until it reaches 300°F (hard crack stage) on a candy thermometer. This guarantees the brittle will set properly and have that signature crunch.
– Add Peanuts and Butter: Carefully stir in the peanuts and butter, mixing well to coat them evenly. Continue cooking until the mixture reaches 305°F.
The peanuts will toast slightly, enhancing their flavor. Be cautious—this step requires constant attention to avoid burning.
– Incorporate Baking Soda: Remove the saucepan from heat and quickly stir in the baking soda. The mixture will foam and lighten in color, which is normal.
This step aerates the brittle, making it lighter and easier to break into pieces.
– Spread the Mixture: Immediately pour the hot mixture onto the prepared baking sheet. Use a greased spatula to spread it thinly and evenly.
Work quickly, as the brittle hardens fast. A thin layer guarantees the right texture—crisp but not too dense.
– Cool and Break: Let the brittle cool completely at room temperature, which usually takes about 30 minutes. Once hardened, break it into pieces by hand or use a knife for cleaner edges.
Store in an airtight container to maintain freshness.

Chef Tips
While making peanut brittle, I’ve found that using a candy thermometer is key to getting the perfect texture—don’t rely on guesswork. Heat the sugar mixture to 300°F (hard crack stage) for that signature crunch.
Work quickly when spreading the brittle; it sets fast. Use parchment paper to prevent sticking, and let it cool completely before breaking.
Store in an airtight container to keep it fresh and crisp.
Frequently Asked Questions
How Long Does Peanut Brittle Stay Fresh?
I’d say peanut brittle stays fresh for about 2 weeks if you store it in an airtight container at room temperature. If you keep it in the fridge, it’ll last up to a month.
Can I Use Other Nuts Instead of Peanuts?
I’d say you can swap peanuts for almonds, cashews, or pecans—just chop ‘em if they’re large. Keep an eye on the texture since some nuts toast faster than peanuts, but the method stays the same.
Is Peanut Brittle Gluten-Free?
Yes, peanut brittle’s gluten-free if I use gluten-free ingredients. I’d double-check labels on sugar, corn syrup, and baking soda to verify they’re safe. If I avoid cross-contamination, I can enjoy it without worry.
What’s the Best Way to Store Peanut Brittle?
I store my peanut brittle in an airtight container at room temperature, away from heat or moisture. If I want it to last longer, I’ll wrap it tightly in foil or plastic before sealing the container.
Why Did My Peanut Brittle Turn Out Chewy?
I think your peanut brittle turned chewy because the sugar didn’t reach the hard crack stage or cooled too slowly. I’d make sure to use a candy thermometer next time and spread it thin right after cooking.
