Why You'll Love This Pecan Brittle Recipe

This recipe holds a special place in my heart because it comes straight from my Aunt Chris’s kitchen. Every holiday season, she would make big batches of this golden, nutty pecan brittle and package it in tins for family and friends. It was one of those treats everyone looked forward to and asked about—crunchy, buttery, and just sweet enough. Now it has become a must-have in my own holiday lineup, and making it always feels a little bit like carrying on her tradition.

I also love that, even though it tastes like something you would buy from a fancy candy shop, it is surprisingly simple and doable at home.

The result is a classic pecan brittle that snaps cleanly, has plenty of pecans in every bite, and never feels sticky or soggy.

This pecan brittle is also perfect for gifting and entertaining. It keeps well at room temperature, travels easily, and looks beautiful broken into rustic shards and piled onto dessert boards, cookie trays, or into little bags and tins. It is one of those recipes that feel nostalgic and homemade, yet polished enough to give as a gift to neighbors, teachers, or coworkers. If you are looking for a reliable, old-fashioned pecan brittle that is both sentimental and practical, this one checks every box.

Ingredients for Pecan Brittle

• 1 cup granulated sugar
• ¼ cup water
• ¼ teaspoon kosher salt
• 2 tablespoon unsalted butter
• 1 cup roasted pecans
• ½ teaspoon vanilla extract
• ½ teaspoon baking soda

How To Make Pecan Brittle

Step 1: Get Everything Ready

Line a rimmed baking sheet with a silicone baking mat or parchment paper. Measure the butter, pecans, vanilla, and baking soda before you start. Once the sugar reaches temperature, the last few steps move quickly.

Step 2: Cook the Sugar Syrup

Add the sugar, water, and salt to a heavy-bottomed saucepan over medium heat. Stir just until the sugar dissolves and the mixture comes to a boil.

Once it starts boiling, stop stirring. Attach a candy thermometer and continue cooking until the syrup reaches 280°F. If sugar crystals collect around the sides of the pan, brush them down with a pastry brush dipped in water.

Step 3: Add Butter and Pecans

Once the syrup reaches 280°F, carefully stir in the butter and roasted pecans. Continue cooking, stirring gently, until the mixture reaches 300°F, which is the hard-crack stage.

Step 4: Add Vanilla and Baking Soda

Immediately remove the pan from the heat. Quickly stir in the vanilla and baking soda just until combined. The mixture will foam and expand, so be careful.

Step 5: Pour and Cool

Immediately pour the hot brittle onto the prepared baking sheet. Use a spatula to quickly spread it into an even layer without making it too thin. Let the brittle cool completely at room temperature for about 30 minutes.

Step 6: Break Into Pieces

Once completely hardened, break the pecan brittle into pieces by hand and serve or transfer it to an airtight container.

My Expert Tips To Make The Best Pecan Brittle

• Have everything measured before you start. Once the syrup approaches 300°F, the recipe moves fast. Have the pecans, butter, vanilla, baking soda, and prepared baking sheet ready before the sugar goes on the stove.
• Stop stirring once the sugar dissolves. Stir the sugar and water only long enough to dissolve the sugar. Once it starts boiling, leave it alone until it reaches 280°F. Continued stirring can encourage crystallization and leave the brittle grainy.
• Use a candy thermometer. The final 300°F hard-crack temperature is what gives the brittle its clean snap. Taking it off too early can leave it chewy, while going much higher can give the caramel a burnt flavor.
• Wash down any sugar crystals on the pan. If you see crystals forming above the syrup, brush them down with a pastry brush dipped in water. This helps keep those crystals from falling back into the syrup and triggering crystallization.
• Use roasted pecans. Roasted pecans have a deeper flavor that stands up better to the caramelized sugar. If yours are raw, toast them first and have them ready before you start the candy.
• Work quickly once the baking soda goes in. The mixture will foam and start setting almost immediately. Stir just until the baking soda and vanilla are incorporated, then pour it onto the prepared pan right away.
• Don’t spread the brittle too thin. Gently spread it into an even layer, but don’t keep working it once it’s on the pan. A little thickness gives you better-sized pieces with plenty of pecans and a satisfying snap.
• Keep moisture away from the finished brittle. Let it cool completely before storing it, then seal it in an airtight container at room temperature. Humidity is one of the fastest ways to turn crisp brittle sticky.

Pecan Brittle FAQS

What is pecan brittle?

Pecan brittle is a hard caramel candy made by cooking sugar with pecans, butter, vanilla, and baking soda. Once the hot mixture cools, it hardens into thin pieces that snap when you break them. This version is made without corn syrup.

Can you make pecan brittle without corn syrup?

Yes. You don’t need corn syrup to make pecan brittle. This recipe uses granulated sugar and water to create the caramel. The key is to stop stirring once the sugar has dissolved and let the syrup cook undisturbed until it reaches the proper temperature.

Do I need a candy thermometer to make pecan brittle?

I strongly recommend one. The sugar mixture needs to reach 300°F, the hard-crack stage, for brittle that cools hard and snaps cleanly. Guessing by color alone makes it much easier to undercook or burn the candy.

Why is my pecan brittle chewy instead of crunchy?

Chewy brittle usually means the sugar mixture didn’t reach 300°F. If it comes off the heat too early, there’s still too much moisture in the candy and it can set soft or bend instead of snapping.

Why did my pecan brittle turn grainy?

Grainy brittle is usually caused by the sugar crystallizing. Stir only until the sugar dissolves, then stop stirring while the syrup cooks to 280°F. If crystals collect on the sides of the saucepan, brush them down carefully with a pastry brush dipped in water.

Can I use other nuts instead of pecans?

Yes. Peanuts, almonds, cashews, or walnuts can replace the pecans. Keep the amount of nuts the same and use roasted nuts when possible for the best flavor.

Can I double this pecan brittle recipe?

I recommend making two separate batches instead. Brittle sets very quickly once the baking soda is added, and doubling the recipe gives you much more hot candy to spread before it hardens. Separate batches are easier to control and give you more consistent results.

How long does homemade pecan brittle last?

Store completely cooled brittle in an airtight container at room temperature for up to 2 weeks. Keep it somewhere cool and dry, and place parchment paper between layers if you’re stacking the pieces.

Should pecan brittle be refrigerated?

No. Refrigeration can expose the brittle to moisture and make it sticky or soft. Room-temperature storage in a tightly sealed container is best.

Can I make pecan brittle when it’s humid?

You can, but brittle absorbs moisture from the air, so humid weather can make it turn sticky more quickly. Transfer it to an airtight container as soon as it has completely cooled and keep the container sealed between servings.
