Cashew Brittle Ingredients
For the Brittle
- Granulated Sugar – Essential for sweetness and structure; don’t substitute it for another sweetener in candy making.
- Water – Helps dissolve the sugar for even cooking; no need for substitutions here.
- Unsalted Butter – Provides richness and prevents sticking; coconut oil works as a dairy-free alternative.
- Light Corn Syrup – Prevents crystallization; avoid using high fructose corn syrup, but you can try agave syrup instead.
- Baking Soda – Creates that signature porous texture; it’s crucial, so be sure not to omit it.
- Roasted and Salted Cashews – The star of the show, offering both crunch and flavor; substitute with pecans or almonds if you prefer.
- Flaky Sea Salt (such as Maldon) – Enhances the sweet-salty profile; kosher salt works too but use a bit less.

Step‑by‑Step Instructions for Irresistible Cashew Brittle
Step 1: Prepare the Baking Sheet
Begin by lining a rimmed baking sheet with parchment paper, ensuring it’s ready for your cashew brittle. Lightly butter both sides of a spatula; this will help when spreading the hot mixture later. Set the prepared baking sheet aside while you work on the sugary concoction.
Step 2: Combine Ingredients
In a medium saucepan, combine the granulated sugar, water, unsalted butter, and light corn syrup. Place the saucepan over medium-high heat, stirring gently until the mixture is well combined. Keep an eye on it, and continue stirring until you see it boiling—this should take about 5 minutes. The sugar should dissolve completely before moving on.
Step 3: Cook the Mixture
Maintain the heat on medium-high and monitor the mixture as it continues to bubble. Using a candy thermometer, cook the mixture until it reaches 300°F, which is the hard crack stage. This should take around 10-15 minutes. You’ll know it’s ready when the color deepens to a golden hue, signaling the perfect caramelization for your cashew brittle.
Step 4: Add Baking Soda
Once the mixture reaches the desired temperature, quickly remove it from the heat. Carefully stir in the baking soda; watch as the mixture foams and increases in volume. This reaction is magical, creating that airy texture in your cashew brittle. Be sure to work swiftly to keep the mixture at the right temperature.
Step 5: Mix in Cashews
After the baking soda has been incorporated, immediately add the roasted and salted cashews into the candy mixture. Stir thoroughly to ensure each cashew is evenly coated with the delicious caramel blend. This step is crucial for achieving the perfect combination of sweet and salty in your cashew brittle.
Step 6: Spread and Cool
Pour the hot cashew mixture onto your prepared baking sheet. Use the buttered spatula to spread it evenly; the brittle will start to harden quickly, so work fast. Once spread, lightly sprinkle flaky sea salt over the top to enhance the flavors. Allow the mixture to cool completely at room temperature.
Step 7: Let Set
After about 30-60 minutes, check the brittle; it should be firm and cool to the touch. Carefully break it into bite-sized pieces using your hands or a sharp knife. Store your irresistible cashew brittle in an airtight container at room temperature, and prepare to enjoy this crunchy confection or gift it to someone special!

Expert Tips for Cashew Brittle
-
Choose the Right Pot: Use a large saucepan to prevent the hot mixture from bubbling over when you add baking soda, ensuring a safe cooking process.
-
Temperature Accuracy: Make sure your candy thermometer is accurate; a slight variation can turn your cashew brittle from perfect to chewy.
-
Work Swiftly: Once you add the cashews, mix quickly! The candy will start to harden fast, so don’t delay in spreading it out.
-
Use Quality Ingredients: Opt for fresh, roasted cashews for the best flavor. Stale nuts can dull the delightful taste of your cashew brittle.
-
Cool Completely: Allow the brittle to set at room temperature—don’t rush this step, as cooling is crucial for achieving the right texture.

Cashew Brittle Recipe FAQs
How do I select the best cashews for this brittle?
Absolutely! Look for high-quality, roasted and salted cashews that are plump and fresh. Check for dark spots or a rancid smell, as these indicate staleness. If you can, opt for products with minimal added ingredients, ensuring that the cashews shine in your sweet treat!
How should I store leftover cashew brittle?
Very good question! Store your cashew brittle in an airtight container at room temperature for up to 8 weeks. Keeping it in a cool, dry place helps maintain that delightful crunch. Avoid refrigerating it, as doing so can make the brittle chewy.
Can I freeze cashew brittle to extend its shelf life?
Absolutely! To freeze your cashew brittle, first, let it cool completely. Then, wrap it tightly in plastic wrap or aluminum foil and place it in an airtight freezer bag. It should stay fresh for up to 3 months. When you’re ready to enjoy, just let it thaw at room temperature for about an hour before indulging, and it’ll be nice and crunchy!
What if my cashew brittle turned out chewy?
Don’t worry; it happens! If your brittle is chewy, it might not have reached the proper temperature during cooking. Next time, double-check that the mixture hits 300°F with a candy thermometer. If you’d like to salvage a batch that has already cooled, try reheating it in a preheated oven at 200°F for about 5-10 minutes—just enough to soften it before breaking it apart again and letting it cool to reset the texture.
Is this cashew brittle safe for people with nut allergies?
No, this cashew brittle is not safe for those with nut allergies, as the main ingredient is cashews. Make sure to clearly communicate this if you’re gifting the brittle to friends. If you’re looking for a nut-free option, consider experimenting with seeds like pumpkin or sunflower seeds as a replacement. Just keep in mind that the flavor and texture will differ!
