Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

To make this delicious homemade peanut brittle, you’ll need the following ingredients:

2 cups granulated sugar: Creates the sweet, caramelized base that hardens into the signature brittle texture.
1 cup light corn syrup: Helps prevent sugar crystallization and gives the candy a smooth, consistent finish.
1/2 cup water: Dissolves the sugar and helps the mixture cook evenly.
2 cups salted roasted peanuts: Provide a crunchy texture and a delicious salty contrast to the sweet candy.
2 tablespoons butter: Adds richness and a subtle buttery flavor.
1 1/2 teaspoons baking soda: Creates tiny air bubbles in the hot candy, making the finished brittle lighter and easier to bite.
1 1/2 teaspoons vanilla extract: Enhances the caramel flavor with a warm, aromatic sweetness.

Directions

Step 1: Prepare Your Baking Sheet

Line a large baking sheet with parchment paper or lightly grease it with butter. Place it on a heat-resistant surface where the brittle can cool undisturbed.

Measure the peanuts, butter, baking soda, and vanilla extract before starting. Once the sugar mixture reaches the correct temperature, you’ll need to work quickly.

Step 2: Make the Sugar Mixture

In a medium, heavy-bottomed saucepan, combine the granulated sugar and water. Stir until the sugar is evenly moistened, then add the light corn syrup.

Place the saucepan over medium heat and cook, stirring occasionally, until the mixture begins to boil gently.

Attach a candy thermometer to the side of the saucepan, making sure the tip is submerged in the syrup without touching the bottom.

Continue cooking until the temperature reaches 250°F (121°C). Avoid increasing the heat too much, as the sugar can burn or cook unevenly.

Step 3: Add the Roasted Peanuts

Once the sugar mixture reaches 250°F, carefully stir in the salted roasted peanuts.

Continue cooking over medium heat, stirring constantly to prevent the peanuts from sticking or burning.

Watch the thermometer closely and cook until the mixture reaches 300°F (149°C), also known as the hard-crack stage.

At this temperature, the syrup will develop a golden amber color and harden into crisp candy as it cools.

Step 4: Add Butter, Baking Soda, and Vanilla

Immediately remove the saucepan from the heat.

Quickly stir in the butter, baking soda, and vanilla extract until everything is incorporated.

The mixture will bubble and foam as the baking soda reacts with the hot sugar. This reaction creates tiny air pockets that give peanut brittle its characteristic delicate crunch.

Work carefully because the candy mixture will be extremely hot.

Step 5: Spread the Peanut Brittle

Immediately pour the hot candy mixture onto the prepared baking sheet.

Using a heat-resistant spatula or spoon, gently spread it into a thin, even layer.

Avoid overworking the mixture, as it begins to harden quickly. A thinner layer produces crisp, easy-to-break pieces.

Step 6: Cool Completely

Allow the peanut brittle to cool at room temperature for at least 30 minutes, or until completely hardened.

Do not place it in the refrigerator to speed up cooling, as moisture can affect its crisp texture.

Once fully cooled, break the brittle into bite-sized pieces using your hands.

Step 7: Serve and Enjoy

Transfer the broken peanut brittle to a serving dish or airtight container.

Enjoy it as a sweet snack, serve it alongside other homemade candies, or package it as a delicious edible gift.

Servings and timing

This homemade peanut brittle recipe makes approximately 50 small pieces, depending on how large you break them.

Total Time: 55 minutes

The cooking time may vary slightly depending on your stove, saucepan, and room conditions. For consistent results, always rely on a candy thermometer rather than cooking time alone.

Variations

One of the best things about homemade peanut brittle is how easily you can customize it with different flavors and ingredients.

1. Mixed Nut Brittle

Replace some or all of the peanuts with roasted almonds, cashews, pecans, or walnuts. Using a combination of nuts creates a more complex flavor and an interesting variety of textures.

2. Chocolate-Dipped Peanut Brittle

Once the brittle has cooled completely, dip half of each piece into melted dark, milk, or white chocolate. Place the pieces on parchment paper until the chocolate sets.

3. Spicy Peanut Brittle

Add a small pinch of cayenne pepper or chili powder when stirring in the butter and vanilla. The gentle heat balances the sweetness and gives the candy a surprising flavor.

4. Cinnamon Peanut Brittle

Stir in 1/2 teaspoon ground cinnamon during the final mixing stage. This adds a warm, comforting flavor that works especially well during the holidays.

5. Honey Peanut Brittle

Replace the light corn syrup with an equal amount of honey for a floral sweetness. Keep in mind that honey may change the candy’s color, flavor, and final texture.

6. Sea Salt Peanut Brittle

Sprinkle a little flaky sea salt over the freshly poured brittle before it hardens. The extra salt enhances the caramel flavor and creates a delicious sweet-and-salty contrast.

7. Coconut Peanut Brittle

Add a small amount of toasted shredded coconut along with the roasted peanuts for a tropical twist. Make sure the coconut is dry to help maintain the candy’s crunchy texture.

Storage/Reheating

How to Store Peanut Brittle

Allow the peanut brittle to cool completely before transferring it to an airtight container.

Keep the container in a cool, dry place at room temperature, away from direct sunlight and moisture.

Properly stored peanut brittle can maintain its quality for approximately 6 to 8 weeks.

For the best results, separate layers with parchment paper to prevent the pieces from sticking together.

Can You Refrigerate Peanut Brittle?

Refrigeration is not recommended because the moisture inside the refrigerator can cause the sugar to absorb humidity.

This can make the brittle sticky, chewy, or softer than intended.

Room-temperature storage in a dry environment is the best way to preserve its crisp texture.

How to Freeze Peanut Brittle

Peanut brittle can be frozen for up to 3 months.

Place the completely cooled pieces in an airtight, freezer-safe container, separating layers with parchment paper if necessary.

When ready to enjoy, allow the sealed container to reach room temperature before opening it. This helps prevent condensation from forming directly on the candy.

Does Peanut Brittle Need Reheating?

No, peanut brittle is meant to be enjoyed at room temperature.

Reheating finished brittle can melt the sugar, affect its texture, and make the candy sticky.

If your peanut brittle becomes soft because of humidity, it may not return to its original crisp texture through reheating.

FAQs

1. Why is my peanut brittle chewy instead of crunchy?

Chewy peanut brittle usually means the sugar mixture did not reach the proper temperature. The syrup needs to reach 300°F (149°C), the hard-crack stage, to produce a crisp candy that snaps when broken. Using a reliable candy thermometer is the easiest way to avoid this problem.

2. Can I make peanut brittle without a candy thermometer?

Yes, but it is more challenging. You can test the syrup by dropping a small amount into cold water. When the candy reaches the hard-crack stage, it should form brittle threads that snap easily. However, a candy thermometer provides more accurate and consistent results.

3. What does baking soda do in peanut brittle?

Baking soda reacts with the hot sugar mixture and creates tiny air bubbles. These bubbles help make the candy lighter and less dense, giving it a more delicate crunch. Without baking soda, peanut brittle can become extremely hard and difficult to bite.

4. Can I use unsalted peanuts instead of salted peanuts?

Absolutely. Unsalted roasted peanuts work well in this recipe. If you prefer a balanced sweet-and-salty flavor, add a small pinch of salt to the candy mixture or sprinkle flaky sea salt over the brittle before it hardens.

5. Why did my peanut brittle turn out too hard?

Peanut brittle naturally has a firm, crunchy texture, but excessive hardness may result from cooking the sugar beyond the recommended temperature, making the candy too thick, or forgetting the baking soda. For a lighter texture, stop cooking at the correct temperature and spread the mixture into a thin layer.

6. Can I substitute honey for corn syrup?

Yes, honey can replace light corn syrup in equal amounts, although it may change the flavor, color, and texture of the finished candy. Honey has a more distinctive taste and can produce slightly different results, so light corn syrup remains the most reliable option for traditional peanut brittle.

7. How do I prevent peanut brittle from sticking to the pan?

Prepare your baking sheet before cooking the sugar mixture. Use good-quality parchment paper or lightly grease the baking sheet with butter. Avoid wax paper, which is not suitable for contact with extremely hot candy. Allow the brittle to cool completely before removing it.

8. How long does homemade peanut brittle last?

When stored in an airtight container in a cool, dry location, homemade peanut brittle can stay fresh for approximately 6 to 8 weeks. Humidity is its biggest enemy because sugar absorbs moisture, which can cause the candy to become sticky or lose its crispness.

9. Can I make peanut brittle ahead of time?

Yes! Peanut brittle is an excellent make-ahead dessert because it keeps well without refrigeration. You can prepare it several days or weeks before a holiday party, celebration, or gift exchange. Store it in an airtight container until you’re ready to serve or package it.

10. Why did my peanut brittle turn dark or taste burnt?

Peanut brittle can burn when the sugar mixture is cooked over excessively high heat or allowed to rise beyond the recommended temperature. To prevent this, use a heavy-bottomed saucepan, maintain medium heat, and monitor the candy thermometer closely. Remove the saucepan from the heat as soon as the mixture reaches 300°F (149°C).
