Ingredients

For the Peanut Brittle

• 3 cups (approximately 450 g) roasted peanuts, preferably unsalted
• 1 cup (200 g) granulated sugar
• ¼ cup (60 ml) water
• 2 tablespoons (28 g) unsalted butter
• 1 teaspoon vanilla extract
• ¼ teaspoon baking soda, optional, for a lighter, airier texture
• A pinch of salt, optional, especially if using unsalted peanuts

For Preparing the Tray

• Nonstick cooking spray or a little butter
• Parchment paper, if desired

Recipe note: Baking soda is an optional suggested addition that creates tiny air bubbles in the caramel, giving the brittle a lighter, more delicate crunch. The original five ingredients can also be used without it for a denser, glassier brittle.

Instructions

1. Prepare Your Baking Tray

Line a large rimmed baking sheet with parchment paper or a silicone baking mat.

Lightly grease the surface with nonstick cooking spray or a little butter.

Measure out all the ingredients before starting. Peanut brittle requires quick handling once the caramel reaches the correct temperature.

Keep the roasted peanuts close by. If they’re cold, gently warm them in a low oven for a few minutes so they don’t cool the caramel too quickly.

2. Prepare the Peanut Mixture

Place the roasted peanuts in a bowl and set aside.

If using unsalted peanuts, add a small pinch of salt for extra flavor.

Make sure the peanuts are dry and free from any loose peanut skins that might affect the finished texture.

3. Dissolve the Sugar

Place the granulated sugar and water in a medium, heavy-bottomed saucepan.

Heat over medium heat, stirring gently at the beginning until the sugar is moistened and begins to dissolve.

Once the mixture starts boiling, stop stirring. Swirl the saucepan gently if necessary to encourage even caramelization.

If sugar crystals form along the sides of the pan, carefully brush them down with a clean pastry brush dipped in water.

4. Cook the Caramel

Allow the sugar syrup to boil until it turns a beautiful golden amber color.

For the most reliable results, use a candy thermometer and cook the syrup to 300°F (149°C), the hard-crack stage.

This temperature is essential for brittle that hardens into a crisp, crunchy candy rather than remaining chewy or sticky.

Watch carefully toward the end because caramel can darken very quickly. Remove the saucepan from the heat as soon as it reaches the correct temperature.

5. Add the Butter and Vanilla

Immediately add the butter to the hot caramel, stirring carefully with a heat-resistant silicone spatula or wooden spoon.

Once the butter has melted, carefully stir in the vanilla extract.

The mixture may bubble slightly when the ingredients are added, so keep your hands and face away from the saucepan.

6. Add the Baking Soda

If using baking soda, sprinkle it evenly over the hot caramel.

Stir quickly but gently. The mixture will foam, expand, and become lighter in color.

This reaction creates tiny air pockets that give the peanut brittle its delicate, airy texture.

7. Fold in the Peanuts

Immediately add the roasted peanuts to the caramel.

Stir quickly until the peanuts are evenly coated.

Work efficiently because the caramel begins to harden as it cools.

8. Spread the Brittle

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

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

You can make it thinner for delicate, easy-to-break pieces or leave it slightly thicker for a more substantial crunch.

Do not touch the mixture with your hands. Hot caramel can cause serious burns.

9. Allow It to Cool Completely

Leave the brittle undisturbed at room temperature for approximately 30–45 minutes, or until completely cool and hard.

Avoid refrigerating it while it is setting, as condensation can affect the crisp texture.

10. Break Into Pieces and Enjoy!

Once the brittle is completely hardened, lift it from the baking sheet.

Break it into irregular bite-sized pieces using your hands or the handle of a sturdy knife.

Arrange the golden pieces on a serving platter or transfer them to an airtight container.

Enjoy your homemade peanut brittle! 🥜

Expert Tips for Perfect Peanut Brittle

• Use a candy thermometer: Reaching 300°F (149°C) is the key to achieving the classic hard, crunchy texture.
• Prepare everything beforehand: Caramel hardens quickly, so measure your ingredients before heating the sugar.
• Choose a heavy-bottomed saucepan: This helps distribute heat evenly and reduces the risk of scorching.
• Avoid stirring once the syrup boils: Excessive stirring can encourage sugar crystallization.
• Use warm peanuts: Room-temperature or slightly warmed peanuts help the caramel remain fluid when they’re added.
• Watch the color carefully: Golden amber caramel has a delicious buttery flavor, while very dark caramel can taste bitter.
• Work quickly: Once the caramel is ready, immediately add the remaining ingredients and spread the mixture.
• Don’t spread too slowly: The caramel becomes difficult to handle as it cools.
• Cool completely: Breaking the brittle too early can cause it to stretch or become sticky rather than snapping cleanly.
• Keep moisture away: Humidity can make homemade brittle sticky, so store it in a dry, airtight container.

Delicious Variations

Cashew Brittle: Replace the roasted peanuts with 3 cups of roasted cashews for a buttery, slightly sweeter variation.

Mixed Nut Brittle: Combine peanuts, almonds, pecans, and cashews for a delicious assortment of crunchy nuts.

Almond Peanut Brittle: Use 2 cups roasted peanuts and 1 cup toasted almonds for extra texture.

Chocolate-Dipped Peanut Brittle: Once the brittle has cooled and been broken into pieces, dip one side in melted dark or milk chocolate. Place on parchment paper until set.

Sea Salt Peanut Brittle: Sprinkle a little flaky sea salt over the brittle immediately after spreading it onto the tray.

Spicy Peanut Brittle: Add a small pinch of cayenne pepper to the peanuts for a sweet-and-spicy candy.

Cinnamon Peanut Brittle: Add ¼ teaspoon ground cinnamon to the caramel for a warm, cozy flavor.

Peanut Butter Brittle: Add a small spoonful of creamy peanut butter to the hot mixture along with the butter for an extra peanut-forward flavor. The texture will be slightly different from traditional brittle.

How to Serve Homemade Peanut Brittle

This crunchy candy is delicious on its own, but it also makes a wonderful addition to:

• Holiday dessert platters
• Christmas cookie trays
• Homemade candy assortments
• Chocolate dessert boards
• Ice cream sundaes
• Brownies and chocolate cakes
• Crumbled dessert toppings
• Gift boxes filled with homemade treats

You can also crush a few pieces and sprinkle them over vanilla ice cream, chocolate mousse, or caramel cheesecake for a delicious crunchy finish.

Make-Ahead Instructions

Homemade Peanut Brittle is an excellent make-ahead candy.

Prepare the brittle several days before a holiday celebration or party. Allow it to cool completely, break it into pieces, and transfer it to an airtight container.

For gifting, prepare the brittle a day or two before packaging so the pieces have time to cool and become completely firm.

Avoid packaging the brittle while it is warm, as trapped moisture can make the caramel sticky.

Storage Instructions

Room Temperature: Store completely cooled peanut brittle in an airtight container in a cool, dry place for up to 2 weeks.

Layering: Place parchment or wax paper between layers to prevent the pieces from sticking together.

Avoid Refrigeration: Refrigeration can introduce condensation when the brittle is removed, which may soften the caramel.

Freezing: Freezing is generally unnecessary and not recommended for the best texture because moisture during thawing can make the candy sticky.

Humidity Tip: Keep the container tightly sealed, especially in warm or humid weather. Open it only when serving and close it promptly.

Frequently Asked Questions

Why is my peanut brittle chewy instead of crunchy?

The caramel probably didn’t reach the hard-crack stage. For a properly crisp brittle, cook the sugar mixture to 300°F (149°C). Undercooking leaves too much moisture in the caramel, resulting in a chewy texture.

Do I really need a candy thermometer?

A candy thermometer is strongly recommended because it provides the most reliable results. Without one, you can use the cold-water test: drop a little caramel into a bowl of ice-cold water. It should immediately form hard, brittle threads that snap when bent.

Why did my caramel turn dark and bitter?

The sugar may have been overheated. Caramel can go from golden amber to burnt very quickly, so watch it closely as it approaches the target temperature.

Why is my peanut brittle sticky?

Sticky brittle can result from undercooked caramel, humid storage conditions, or exposure to moisture. Make sure the syrup reaches 300°F (149°C) and store the finished candy in an airtight container.

Why did my brittle develop white or grainy spots?

This can happen when sugar crystallizes during cooking. Avoid stirring after the syrup boils, use a clean saucepan, and carefully wash down any sugar crystals on the sides with a wet pastry brush.

Can I use salted peanuts?

Absolutely! Salted roasted peanuts add a wonderful sweet-and-salty flavor. If using them, omit the optional extra pinch of salt.

Can I use raw peanuts?

Yes, but they need to be roasted first for the best flavor and texture. Using already-roasted peanuts is easier and ensures the nuts are ready when the caramel is prepared.

What does baking soda do in peanut brittle?

Baking soda reacts with the hot caramel and releases carbon dioxide, creating tiny air pockets. This makes the brittle lighter and easier to bite through. Without it, the candy will have a denser, harder texture.

Can I double the recipe?

It’s better to prepare separate batches rather than doubling the quantities in one saucepan. A larger batch may cook unevenly and become difficult to spread before it hardens.

Can I make peanut brittle without butter?

Butter adds richness and helps create a smoother caramel flavor. It can be omitted in some traditional sugar-and-peanut brittle recipes, but the texture and flavor will be different.

Is peanut brittle a good homemade gift?

Definitely! Once completely cooled, break it into attractive pieces and package them in decorative tins, clear candy bags, or holiday gift boxes. Include a note about the peanut allergen.
