A Sweet Taste of Home: Grandma’s Nut Brittle Recipe

Grandma’s Nut Brittle Recipe is the kind of sweet that fixes a craving and a mood all at once. Maybe you want something crunchy, simple, and nostalgic, but you’re short on time or ingredients. I get it. This brittle uses pantry basics, comes together fast, and makes a perfect gift tin treat. I’ve made it so many times that the steps feel like muscle memory, and today I’m sharing exactly how I do it, plus what to avoid so you don’t end up with a sticky mess. Ready for that snap?

Peanut Brittle Baking Tip

Let’s start with the number one thing that makes or breaks brittle: heat control. Brittle is about timing, not fancy tools. The magic happens when sugar hits the right temperature and you add baking soda at just the right moment. That’s what creates those tiny bubbles and that light, crisp bite. If you’ve ever had brittle turn out sticky or too hard to chew, it’s usually a temperature issue or stirring at the wrong time.

Here’s my go-to tip that rarely fails: once the sugar dissolves and the mixture begins to boil, stop stirring. Stirring during the boil can cause crystallization. Just give the pot a gentle swirl now and then. Keep the heat steady on medium to medium-high. And use a candy thermometer if you have one. If not, I’ll share a quick no-thermometer trick below.

Another little trick: warm your baking sheet in the oven for a few minutes while you cook the syrup. Spreading hot brittle onto a warm surface gives you extra seconds to get it thin and even. I learned this the hard way on a cold winter day when my first batch set up before I could smooth it out. Ever since, warming the pan has been a game changer.

If you’re building a holiday treat tray, pair your brittle with something playful like these 5-minute Christmas bauble cookies. That combo looks festive and tastes like joy.

“I followed your warming-the-pan trick and the brittle finally spread perfectly. It snapped clean and didn’t stick to my teeth. New holiday favorite.” – Taylor R.

How to make nut brittle

I’ll walk you through the way my family makes brittle. It’s straightforward, quick, and reliable. You can use peanuts, pecans, almonds, or a mix. I love salted roasted peanuts for classic flavor and that nostalgic snap. This is the heart of my Grandma’s Nut Brittle Recipe tradition, and it never disappoints.

Ingredients and tools

• 1 cup granulated sugar
• 1/2 cup light corn syrup
• 1/4 cup water
• 2 tablespoons unsalted butter
• 1 teaspoon vanilla extract
• 1 teaspoon baking soda
• 1 to 1 1/2 cups roasted salted peanuts or your favorite nuts
• Pinch of salt if your nuts are unsalted
• Tools: heavy-bottomed saucepan, heat-safe spatula, candy thermometer if available, baking sheet lined with parchment or silicone mat

Step-by-step guide

Prep: Lightly grease your lined baking sheet or silicone mat. Keep your baking soda, vanilla, and butter measured and ready. Warm the baking sheet in a low oven while you cook – this helps spreading.

Cook the syrup: In a saucepan, combine sugar, corn syrup, and water. Cook over medium heat, stirring only until the sugar dissolves. Once it starts to boil, stop stirring. Let it bubble steadily. If using a thermometer, you’re heading to about 300 F – also called the hard-crack stage.

No thermometer? Drop a tiny bit of syrup into a glass of very cold water. If it forms brittle, breakable threads that snap, you’re ready. If it bends like taffy, keep cooking and check again in 30 seconds.

Add the nuts: When the syrup hits 280 F or starts to take on a light golden color, stir in the nuts with a heat-safe spatula. Keep cooking and watching closely. When the mixture is a rich golden-amber and around 300 F, remove from heat.

Finish: Immediately stir in butter and vanilla. Then quickly sprinkle baking soda over the top and stir. It will foam and lighten. That aeration is key for a clean, crisp snap.

Spread: Pour the mixture onto your warm baking sheet. Use the spatula to push it out thin. Work fast, but don’t stress over perfection. Let it cool completely, then break into pieces.

Storage

Brittle’s biggest enemy is humidity. Keep it super dry and it stays crunchy for weeks. I stash mine in an airtight tin or a sealed glass jar with a tight lid. Separate layers with parchment so pieces don’t stick together. If your kitchen runs humid, tuck a small food-safe desiccant pack or a pinch of uncooked rice in a tiny mesh pouch near the container – not touching the brittle – to absorb moisture.

How long it lasts

At room temp in a sealed container, it’s best within 2 weeks but can last up to a month. Don’t refrigerate; fridges are humid and can make brittle tacky. Freezing is possible, but it can pick up moisture as it thaws and lose crunch. If you do freeze it, wrap tightly and thaw still wrapped at room temp. For snack swaps and crunchy cravings, I also keep a jar of these baked banana chips nearby – they’re another crispy favorite.

Tips for the best homemade nut brittle

Equipment notes that keep things easy

Use a heavy-bottomed saucepan so the sugar heats evenly. Thin pots scorch quickly. A silicone spatula helps you scrape without sticking, and a silicone baking mat makes removal effortless. If you’re nervous about working with hot syrup, wear oven mitts while pouring and spreading – there is no award for burnt fingers.

Flavor and texture tips:

Warm the pan before you pour. This gives you those extra seconds for a thin spread. Sprinkle a little flaky salt while it’s still warm for a salty-sweet finish. And don’t skip the baking soda – it aerates the candy for that signature snap. If you love this style of classic comfort, you might also enjoy these cozy fall sips and bites, like a homemade latte moment with the best pumpkin spice latte recipe, perfect next to a jar of brittle on a crisp evening.

Thermometer confidence:

Target 300 F for a firm brittle. If your last batch was too sticky, you likely stopped under 300 F. Too hard or tastes burnt? That’s over 320 F. Adjust your heat so the temperature climbs steadily, not rapidly.

Gifting note:

Brittle travels well. Slip pieces into small bags, tie with ribbon, add a tag, and you’re set. For a sweet cookie companionship, these apple pie cookies make a homey duo in gift boxes.

Additions and Variations

Once you master the base of my Grandma’s Nut Brittle Recipe, you can riff endlessly. Change nuts, add warm spices, or drizzle with chocolate. Keep the core method the same and you’ll be golden.

• Nuts: Almond brittle is elegant, pecan brittle tastes buttery, and cashew brittle is extra creamy. Mixed nuts are great for texture.
• Spices: A pinch of cinnamon or chai spice is lovely for fall. Cayenne gives a gentle heat that plays nicely with caramel notes.
• Chocolate: Once the brittle cools, drizzle with melted dark chocolate and let set. Fancy without much effort.
• Citrus: Stir a little orange zest into the nuts before adding them to the syrup for a bright, fragrant bite.
• Seeds: Mix in toasted sesame or pumpkin seeds for a nutty crunch without extra cost.

Serving ideas: Break into shards for an ice cream topper, or crush a handful and sprinkle over yogurt. For a festive platter, add a few of these quick beauties: bauble cookies for sparkle and a comforting bowl of warm butternut squash soup on the side if you want a savory-sweet spread. Trust me, it works.

This season, I’ll be gifting batches tied with plaid ribbon and a little handwritten note that simply says: “Made with love.” It’s the kind of simple sweet that reminds everyone of home.

Common Questions

Do I have to use corn syrup?

Corn syrup helps prevent crystallization. If you skip it, the risk of grainy texture rises. Light honey can work in a pinch, but watch the heat, as honey darkens quickly.

Can I make this without a thermometer?

Yes. Use the cold water test. Drop a bit of syrup into very cold water. If it snaps brittle, you’re ready. If it bends, keep cooking another 30 seconds and test again.

Why did my brittle turn sticky the next day?

Humidity or undercooking. Store airtight away from moisture and cook the syrup to about 300 F. A tiny pinch of baking soda also helps the crisp texture.

What nuts are best?

Roasted salted peanuts are classic and affordable. Almonds give a clean crunch, pecans are buttery, and cashews are mellow. Use what you love or a mix.

How do I clean the pot after making brittle?

Fill the pot with water and bring to a simmer. The sugar melts off easily. No heavy scrubbing needed.

A sweet wrap-up you can taste

Making my Grandma’s Nut Brittle Recipe is about more than sugar and nuts. It’s a quick project that fills the kitchen with caramel aroma and gives you a treat to share or stash for yourself. Keep an eye on temperature, warm the pan, and let the baking soda work its magic.
