Ingredients You’ll Need
Gathering simple, pantry-friendly ingredients is all it takes to create this show-stopping snack. Each ingredient plays a vital role in building the texture, flavor, and beautiful amber color of the brittle.
- 1 cup granulated sugar: The sweet foundation that caramelizes to form that irresistible crunchy base.
- ½ cup light corn syrup: Helps prevent crystallization, ensuring your brittle stays smooth and glassy.
- ¼ cup water: Assists with dissolving the sugar evenly while cooking.
- 1 cup roasted, unsalted cashews, roughly chopped: Adds nutty crunch and rich flavor, making every bite deeply satisfying.
- 2 tablespoons unsalted butter: Contributes a luscious richness and tender snap to the brittle.
- 1 teaspoon vanilla extract: Enhances the caramel notes with a warm, inviting aroma.
- ½ teaspoon baking soda: Creates tiny bubbles in the mixture, giving the brittle its signature airy texture.
- ¼ teaspoon salt: Balances the sweetness and heightens all the flavors for a well-rounded taste.
How to Make Cashew Brittle Recipe
Step 1: Prepare Your Workspace
Start by lining a baking sheet with parchment paper or a silicone mat and lightly grease it. This simple step ensures your brittle won’t stick and will release beautifully once cooled.
Step 2: Combine Sugar, Corn Syrup, and Water
In a heavy-bottomed saucepan over medium heat, combine the granulated sugar, light corn syrup, and water. Stir gently until the sugar fully dissolves, causing the liquid to look clear rather than grainy, then stop stirring. This approach prevents crystal formation and gives the brittle its clear, polished finish.
Step 3: Boil to the Hard Crack Stage
Let the mixture boil without stirring until it reaches 300°F (150°C), also known as the hard crack stage, which usually takes 10 to 15 minutes. This temperature ensures your brittle will snap perfectly and not be chewy or sticky.
Step 4: Add Cashews and Flavorings
Remove the pot from the heat immediately and quickly stir in the chopped cashews, unsalted butter, vanilla extract, salt, and baking soda. Expect the mixture to foam up – that’s the magic of baking soda reacting, creating a light and airy texture within the brittle. Stir rapidly to combine everything evenly.
Step 5: Spread and Cool
Pour the hot, bubbling mixture onto your prepared baking sheet. Using a greased spatula, spread it quickly and evenly before it hardens. Allow it to cool completely at room temperature until it becomes firm enough to snap into pieces.
How to Serve Cashew Brittle Recipe

Garnishes
While this Cashew Brittle Recipe is delightful on its own, sprinkling a pinch of flaky sea salt on top right after spreading can elevate the flavor with a subtle contrast. For a festive touch, sprinkle finely chopped dark chocolate or edible gold dust for a glamorous look.
Side Dishes
This crunchy treat pairs wonderfully with a cup of strong coffee or a bold black tea. Its sweet, nutty crunch can also complement creamy desserts like vanilla ice cream or a soft cheesecake, providing a satisfying textural contrast.
Creative Ways to Present
Looking to impress guests? Break the brittle into uniform shards and serve it in a decorative bowl alongside a cheese platter or a hot cocoa bar. Alternatively, wrap broken pieces in cellophane bags tied with ribbon to create thoughtful homemade gifts that everyone will rave about.
Make Ahead and Storage
Storing Leftovers
Store your leftover Cashew Brittle Recipe in an airtight container at room temperature. Keeping it away from humidity is crucial to maintaining that perfect snap. It will stay fresh and crunchy for up to two weeks, making it a convenient treat to have on hand.
Freezing
If you want to keep your brittle even longer, freeze it in a sealed container or freezer bag. When wrapped tightly, it can last for several months. Just thaw it at room temperature before enjoying, and it will retain its delightful crunch.
Reheating
Generally, there’s no need to reheat brittle. If it softens slightly, letting it sit in air for a few hours will help it regain some of its crunch. Avoid microwaving as it can melt the sugar unevenly and ruin the texture.
FAQs
Can I use salted cashews in this brittle?
Absolutely! Using roasted salted cashews will add a delicious sweet-salty contrast, but be sure to reduce the added salt slightly to avoid overpowering the flavors.
What if I don’t have a candy thermometer?
While a candy thermometer is the best tool for accuracy, you can test the hard crack stage by dropping a small amount of the cooked sugar mixture into cold water — if it hardens into brittle threads that snap easily, it’s ready.
Why does my brittle sometimes turn out sticky?
Sticky brittle often results from humidity or not reaching the correct temperature. Make sure to cook the sugar mixture until it reaches the hard crack stage and store the brittle in a dry, airtight container at room temperature.
Can I substitute cashews with other nuts?
Definitely! Pecans, almonds, or peanuts work wonderfully in this recipe, each giving a unique flavor and texture to the brittle.
Is this recipe gluten-free and vegetarian?
Yes, this Cashew Brittle Recipe is naturally gluten-free and vegetarian, making it suitable for those with these dietary preferences.
