Peanut Brittle is one of those old-fashioned treats that never goes out of style. It has that glossy golden snap, deep buttery sweetness, and the kind of roasted peanut flavor that makes every bite feel a little nostalgic. Whether you grew up finding it in holiday tins or discovered it at a local candy shop, homemade brittle always feels extra special.

What makes this version so appealing is how simple the ingredient list is compared to the flavor it delivers. With sugar, corn syrup, butter, peanuts, and a few pantry basics, you can create a candy that looks impressive and tastes even better than store-bought. Once you hear that crisp crack and taste the salty-sweet crunch, it is easy to see why this recipe has lasted for generations.

Why You’ll Love This Peanut Brittle

This Peanut Brittle is wonderfully crisp without being hard in an unpleasant way, and it has the kind of balanced sweetness that keeps you reaching for another piece. The peanuts bring warmth and crunch, while the butter and vanilla round everything out with a rich homemade finish.

It is also a great recipe for gifting, party trays, and make-ahead treats. Because it stores so well, you can make it ahead for the holidays or package it in little bags for neighbors and friends. It looks beautiful, travels well, and always feels thoughtful.

Why Does Peanut Brittle Turn Out So Crisp and Light?

The magic comes from cooking the sugar mixture to the right stage and then adding baking soda right at the end. That small amount of baking soda creates tiny bubbles throughout the candy, which gives peanut brittle its signature airy texture and helps it snap cleanly instead of turning dense and heavy.

The other key is working quickly once the mixture is ready. As soon as the brittle reaches the proper color and temperature, you stir in the final ingredients and spread it out while it is still fluid. That quick finish is what gives you those thin, glossy sheets with the best crunch.

Ingredients for the Peanut Brittle

This recipe uses everyday pantry staples, but each one has an important role in the finished candy. The sugar and corn syrup build the crisp candy base, the peanuts bring that classic roasted crunch, and the butter, vanilla, and baking soda create the flavor and texture that make homemade brittle so memorable.

• Granulated sugar gives the brittle its sweetness and creates the hard candy structure.
• Light corn syrup helps keep the texture smooth and prevents the sugar from crystallizing too early.
• Water dissolves the sugar and helps everything cook evenly in the beginning.
• Unsalted butter adds richness and gives the brittle a more rounded flavor.
• Salted roasted peanuts are the heart of the recipe and bring the salty crunch that makes brittle irresistible.
• Salt sharpens the sweetness and keeps the candy from tasting flat.
• Vanilla extract adds warmth and a classic homemade candy aroma.
• Baking soda creates the tiny bubbles that make the brittle lighter, crispier, and easier to bite.

How To Make the Peanut Brittle

Making Peanut Brittle is easier than it looks, but timing matters. Once the sugar mixture reaches the right stage, the final steps move quickly, so it helps to measure everything ahead of time and line your baking sheet before you start cooking.

Step 1: Prepare the Pan and Ingredients

Lightly butter a large baking sheet or line it with a silicone baking mat. Measure the vanilla and baking soda into small bowls so they are ready to go. This keeps the process smooth once the candy is hot.

Step 2: Start the Sugar Mixture

In a heavy saucepan, combine the sugar, corn syrup, water, and butter over medium heat. Stir until the sugar dissolves and the butter melts, then stop stirring and let the mixture cook.

Step 3: Add the Peanuts

Once the syrup is bubbling steadily, stir in the peanuts and continue cooking. Stir often at this stage so the nuts toast evenly and the mixture does not scorch on the bottom of the pan.

Step 4: Cook Until Deep Golden

Keep cooking until the candy reaches about 300°F on a candy thermometer and turns a rich golden color. This is the hard crack stage, which gives the brittle its signature snap.

Step 5: Finish with Vanilla and Baking Soda

Remove the pan from the heat and quickly stir in the salt, vanilla, and baking soda. The mixture will foam and lighten almost immediately, which is exactly what you want.

Step 6: Spread the Brittle

Pour the mixture onto the prepared pan right away. Use a buttered spatula to gently spread it thinner if needed, but do not overwork it or you may flatten the airy texture.

Step 7: Cool and Break into Pieces

Let the brittle cool completely at room temperature until firm. Once fully set, break it into pieces and store it in an airtight container.

Serving and Storing Peanut Brittle

Peanut Brittle makes about 12 servings, depending on how large you break the pieces. It is perfect for dessert trays, edible gifts, afternoon coffee breaks, or a sweet little bite after dinner.

Store it in an airtight container at room temperature for up to two weeks. Keep it in a cool dry place so it stays crisp. If your kitchen is humid, place parchment between layers and avoid refrigerating it, since extra moisture can make the brittle sticky.
