Why Make Homemade Brittle?
Brittle stands out among homemade sweets for several reasons:
- Versatile: Easily customized with any nuts, seeds, or flavorings you love.

- Simple ingredients: You probably have sugar, butter, and nuts at hand.
- Classic treat: The contrast of sweet, salty, and crispy is simply irresistible.
What is Brittle?
Brittle is a type of candy made by cooking sugar and syrup until caramelized, then adding nuts and a leavening agent (usually baking soda) before spreading thinly and letting harden. The result is a shattering crunchy candy packed with roasted nut flavor and a glossy caramel base. It’s similar to toffee but less buttery and more transparent in color and texture.
Brittle vs. Toffee: Key Differences
| Brittle | Toffee |
|---|---|
| Minimal butter, glossy, glassy texture | High butter, matte, softer caramel color |
| More shattering crunch | Creamier, more caramel-forward flavor |
| Typically contains nuts | Often plain or topped with chocolate/nuts |
Essential Ingredients for Mixed Nut Brittle
- Unsalted butter: Contributes richness and flavor.
- Granulated sugar: Forms the base caramel.
- Light corn syrup: Prevents crystallization, keeps the candy smooth.
- Water: Dissolves sugar to start, then cooks off.
- Cashews: Roasted and lightly salted for flavor and crunch.
- Pecans: Roughly chopped for texture.
- Peanuts: Roasted, unsalted for nutty depth.
- Almonds: Slivered for added crunch.
- Kosher salt: Enhances flavor and balances sweetness.
- Baking soda: Creates air bubbles for delicate crunch.
- Vanilla extract: Adds warm aromatic notes.
- Flaky sea salt: Optional, for finishing.
Step-by-Step Directions: How to Make Mixed Nut Brittle
- Prepare Your Pan
Grease a large baking sheet with butter, ensuring full coverage to prevent sticking. Set aside. - Cook the Syrup
In a large saucepan, combine granulated sugar, light corn syrup, and water. Cook over medium heat, swirling the pan occasionally (don’t stir) until a candy thermometer reads 285°F (hard-ball stage)—this generally takes 16 to 18 minutes. - Add the Nuts
With the mixture at temperature, stir in cashews, pecans, peanuts, almonds, and kosher salt. Stir constantly with a wooden spoon. Let the mixture reach 300°F (hard-crack stage), which takes about 3–5 minutes more. Watch closely to avoid burning. - Finish the Brittle Base
Remove from heat immediately. Add room temperature butter, baking soda, and vanilla extract. Stir until the mixture is evenly foamy and well combined—this step is crucial for the brittle’s signature texture. - Pour & Spread Quickly
Immediately pour the foamy caramel-nut mixture onto your prepared baking sheet. Using a spatula (buttering it first can help), spread the mixture into a thin, even layer before it hardens. Sprinkle with flaky sea salt, if using. - Cool & Break
Allow the brittle to cool completely (about 30 minutes). Once set, break into pieces or shards using your hands or a mallet. - Store Properly
Store brittle in an airtight container at room temperature for up to 1 week. Brittle can last longer in cool, dry conditions.
Troubleshooting & Expert Tips
- Set Up Before You Start: Brittle hardens rapidly once off heat—prep your pan, chop nuts, and pre-measure your ingredients.
- Candy Thermometer: Essential for accuracy. Clip onto the pot or check frequently. Alternative: Drop a teaspoon of syrup in cold water—it should form firm, but not brittle, threads (hard-crack stage) .
- Swirl, Don’t Stir: Stirring dissolved sugar during caramelization causes crystallization. Swirl pan gently until adding nuts.
- Work Fast: Once you add baking soda, the mixture will foam up. Immediately spread it so it doesn’t become a thick lump.
- Custom Nuts: Experiment with pistachios, hazelnuts, macadamias, or even pumpkin seeds for different flavors.
- Flavor Variations: Try adding citrus zest, cinnamon, ground espresso, or cayenne pepper with vanilla for gourmet twists.
Frequently Asked Questions (FAQs)
What if I don’t have a candy thermometer?
You can test the sugar syrup by dropping a little into a bowl of cold water. If it forms firm, flexible threads between your fingers, you’ve reached the hard-crack stage. However, for consistent results and safety, use a clip-on candy thermometer if possible .
What others are reading
How do I keep my brittle from being sticky or chewy?
Cooking to the right temperature (300°F/150°C) is crucial. Undercooked syrup will result in a chewy, sticky texture. Use a candy thermometer, or the cold water test as backup.
Can I double or halve the recipe?
Yes, but ensure your saucepan is large enough for a double batch—hot sugar can foam up significantly. For smaller batches, adjust cooking times, but don’t compromise on temperature accuracy.
What’s the best way to break brittle?
Once completely cooled, use your hands to snap brittle into shards. You can also place a clean tea towel over the slab and tap lightly with a mallet.
How should I store brittle, and how long does it keep?
Keep brittle in a sealed, airtight container at room temperature. Avoid humidity, which softens candy. Brittle remains crisp for up to 1 week; it may last longer if kept totally dry.
Creative Brittle Variations
- Peanut Brittle: Use only roasted peanuts for a traditional Southern-style treat. Add a pinch of cinnamon for warmth.
- Chocolate-Dipped Brittle: Once chilled and broken, dip shards in melted dark or milk chocolate. Let harden for a premium candy gift.
- Spiced Brittle: Add cayenne, chili powder, or black pepper to the sugar mixture for a sweet-heat twist.
- Tropical Brittle: Incorporate shredded coconut, macadamia nuts, or lime zest for a sunny flavor profile.
- Seed Brittle: Substitute sunflower, pumpkin, or sesame seeds for nuts for allergy-friendly crunch.
Tips for Homemade Candy Success
- Organize all ingredients and tools before starting—the process moves fast.
- Use oven mitts, as sugar syrup is extremely hot and can cause burns.
- Clean-up is easier if you soak pans and utensils immediately after use.
How to Package Brittle for Gift Giving
- Food-safe cellophane bags: Fill with brittle shards and tie with ribbon.
- Tins or jars: Line with parchment and layer brittle inside.
- Label with flavor and expiration date for homemade holiday gifts.
