Cashew Brittle Ingredients
For the Brittle
- Granulated Sugar – Provides sweetness and structure; no substitutions recommended for traditional brittle.
- Water – Helps dissolve the sugar and aids in achieving the right caramel consistency; essential for your cashew brittle.
- Unsalted Butter – Adds richness and prevents sticking; can substitute with vegan butter for a dairy-free version.
- Light Corn Syrup – Prevents crystallization of sugar and adds chewiness; avoid high fructose corn syrup as a substitute.
- Baking Soda – Creates a porous texture, making the brittle light and crunchy; don’t omit, as it affects the texture.
- Roasted and Salted Cashews – Core ingredient providing crunch and flavor; can substitute with almonds or peanuts for different nutty variations.
- Flaky Sea Salt – Enhances flavor and adds visual appeal; Maldon is preferred, but any flaky sea salt will do.
Step‑by‑Step Instructions for Cashew Brittle
Step 1: Prepare Your Baking Sheet
Start by preparing a rimmed baking sheet lined with parchment paper. Generously grease both sides of a spatula with unsalted butter to prevent sticking. This set-up will help you pour and shape your cashew brittle easily once it’s cooked, so make sure your workspace is ready while you gather the ingredients.
Step 2: Combine Key Ingredients
In a medium-sized saucepan, combine granulated sugar, water, unsalted butter, and light corn syrup. Set the pan over medium-high heat and stir the mixture gently until it reaches a boil. Watch closely as it begins to bubble, keeping an eye out for the sugar to fully dissolve and start turning into a syrupy consistency.
Step 3: Cook to Hard Crack Stage
Continue cooking the mixture without stirring, allowing it to reach the hard crack stage at 300°F (149°C). This should take approximately 10–12 minutes. You’ll know it’s ready when the mixture transforms into a deep amber color, indicating that the sugar has caramelized beautifully, making your cashew brittle wonderfully rich.
Step 4: Incorporate Baking Soda
Remove the saucepan from the heat and immediately stir in the baking soda. Be cautious, as the mixture will foam up and expand in volume. This reaction is crucial for achieving the light and crunchy texture of your cashew brittle, so make sure to mix it thoroughly until well combined.
Step 5: Mix in Cashews
Quickly add the roasted and salted cashews into the hot mixture, stirring well to ensure they’re fully coated. The warmth of the brittle will make it easier to mix, while the nuts lend all their flavor. Be swift, as the mixture will start to thicken quickly, making it imperative to act fast.
Step 6: Pour onto Baking Sheet
Carefully pour the cashew mixture onto your prepared baking sheet. Use your buttered spatula to spread it into an even layer, working rapidly as it sets up quickly. The even layer is essential for uniform coolness, ensuring that every bite of your cashew brittle is perfectly crunchy.
Step 7: Season with Sea Salt
Sprinkle flaky sea salt over the spread cashew brittle while it’s still warm. The salt not only enhances the flavor but also adds an appealing visual touch to your finished treat. Be generous, but ensure the salt is evenly distributed to balance the sweetness of the sugar.
Step 8: Allow to Cool Completely
Set the baking sheet aside and allow the cashew brittle to cool completely for about 30 minutes. As it cools, it will harden into a satisfying crunch. Resist the urge to sample it too soon, as patience now will reward you with the perfect texture in your delicious cashew brittle.
Step 9: Break into Pieces
Once fully cooled, use your hands or a knife to break the cashew brittle into bite-sized pieces. The crunchy texture will make it easy to snap, and these delightful squares are perfect for snacking or gifting! Enjoy the fruits of your labor, knowing you’ve created a sweet treat that everyone will love.

How to Store and Freeze Cashew Brittle
Room Temperature: Store cashew brittle in an airtight container to keep it crunchy. It can last up to 8 weeks at room temperature.
Fridge: Avoid refrigerating cashew brittle, as this can cause it to become chewy rather than crunch.
Freezer: If you need to store it longer, freeze pieces of cashew brittle in a freezer-safe bag. It can be stored for up to 2 months. Just thaw at room temperature before enjoying!
Reheating: If the brittle softens, a quick 5-minute stay in a warm oven (around 200°F) can help regain its crunch before serving.
Make Ahead Options
These Cashew Brittle pieces are an excellent choice for meal prep enthusiasts! You can prepare the mixture up to 24 hours in advance by cooking it through step 5, then allowing it to cool completely before storing it in an airtight container at room temperature. This will keep the brittle fresh and prevent it from getting chewy. When you’re ready to enjoy your cashew brittle, simply spread the nut mixture on the baking sheet, season with flaky sea salt, and allow it to fully cool before breaking it into pieces. With this make-ahead strategy, you’ll save time while still delivering a delightful treat just as delicious as if made fresh!

Cashew Brittle Recipe FAQs
What type of cashews should I use for the best flavor?
I recommend using roasted and salted cashews for an enhanced flavor profile. The roasting amplifies the nutty taste while the salt balances the sweetness of the brittle beautifully. If you’re in the mood for experimentation, you can also try using almonds or peanuts for a unique twist!
How do I store leftover cashew brittle?
Storage is simple! Just keep your cashew brittle in an airtight container at room temperature. This way, it will stay crispy for up to 8 weeks. Just remember to avoid the fridge, as chilling can make it lose that wonderfully crunchy texture.
Can I freeze cashew brittle for later use?
Absolutely! To freeze your cashew brittle, simply place it in a freezer-safe bag or airtight container. It can last up to 2 months in the freezer. When you’re ready to enjoy it, just thaw it at room temperature. If it has softened, you can warm it in a 200°F oven for about 5 minutes to regain its crunch.
What if my cashew brittle turned out chewy?
If you’re encountering chewy cashew brittle, it typically means that the sugar mixture didn’t reach the hard crack stage (300°F). For next time, invest in a candy thermometer to ensure you’re hitting the right temperature. If you’re in a pinch and your current batch is chewy, you can quickly reheat it in a saucepan over low heat and remelt it, stirring in some more baking soda as it softens, then re-spread it onto a baking sheet to allow it to harden again.
Is cashew brittle suitable for people with nut allergies?
Unfortunately, due to the primary ingredient being cashews, this brittle is not suitable for anyone with nut allergies. However, you can explore alternatives by using seeds like pumpkin or sunflower for a similar crunch, but the flavor will differ from traditional nut-based brittles.
