Ingredients

1 cup granulated sugar
1/2 cup light corn syrup
1/4 cup water
2 cups roasted unsalted peanuts
2 tablespoons unsalted butter
1/2 teaspoon baking soda
1/2 teaspoon vanilla extract

Optional

1/4 teaspoon salt, especially if using unsalted peanuts
Flaky sea salt for sprinkling on top

Preparation

1. Prepare Your Baking Sheet

Before you begin cooking the candy, line a large baking sheet with parchment paper or a silicone baking mat.

Lightly grease a spatula with butter or nonstick cooking spray. Once the brittle reaches the correct temperature, you’ll need to work quickly, so it’s important to have everything ready before you start.

Measure the butter, baking soda, vanilla, and peanuts and keep them close to the stove.

2. Combine the Sugar Mixture

In a heavy-bottomed medium saucepan, combine the granulated sugar, light corn syrup, and water.

Place the saucepan over medium heat and stir gently until the sugar begins to dissolve.

Continue heating until the mixture comes to a steady boil.

Once boiling, avoid excessive stirring because this can encourage sugar crystals to form around the sides of the pan.

3. Cook the Sugar Syrup

Allow the sugar mixture to continue cooking over medium heat.

For the most reliable results, use a candy thermometer. Cook until the syrup reaches approximately 250°F (121°C).

The mixture should be clear and bubbling steadily.

Candy-making requires attention, so don’t walk away from the saucepan during this stage.

4. Add the Peanuts

Carefully stir the roasted peanuts into the hot sugar syrup.

Continue cooking while stirring frequently to prevent the peanuts and sugar from burning on the bottom of the saucepan.

As the mixture cooks, it will gradually develop a beautiful golden caramel color.

5. Cook to the Hard-Crack Stage

Continue cooking the peanut mixture until the candy thermometer reaches approximately 300°F (149°C), which is known as the hard-crack stage.

The mixture should now have a rich golden-amber appearance and smell pleasantly caramelized.

Be careful not to cook it too far beyond this point because caramel can go from perfectly golden to burnt very quickly.

6. Add the Butter and Vanilla

Remove the saucepan from the heat.

Immediately add the unsalted butter and vanilla extract.

Stir carefully until the butter has melted and is fully incorporated into the caramel.

The mixture will be extremely hot, so use a long-handled wooden spoon or heat-resistant spatula and avoid touching the candy directly.

7. Add the Baking Soda

Quickly sprinkle the baking soda over the hot candy mixture.

Stir it in immediately.

You’ll notice the mixture becoming lighter and foamy. This reaction creates tiny air bubbles throughout the candy, helping give peanut brittle its characteristic light, crisp texture rather than an extremely hard, dense consistency.

Don’t overmix at this stage.

8. Spread the Brittle

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

Using the greased spatula, quickly spread the candy into a thin, even layer.

The thinner you spread it, the lighter and crispier the finished brittle will be.

Work quickly because the candy begins setting almost immediately after leaving the saucepan.

If desired, sprinkle a tiny amount of flaky sea salt over the surface while the brittle is still warm.

9. Allow It to Cool

Leave the peanut brittle undisturbed at room temperature until it has completely cooled and hardened.

This generally takes around 30–45 minutes, depending on the thickness of the brittle and room temperature.

Do not refrigerate the hot brittle. Allowing it to cool naturally helps maintain the proper crisp texture.

10. Break into Pieces

Once completely cool, lift the brittle from the baking sheet.

Break it into irregular bite-sized pieces using your hands.

The pieces don’t need to be identical. The rustic, uneven shapes are part of the traditional appearance of homemade peanut brittle.

Arrange them in a serving bowl or store them immediately in an airtight container.

Important Tips for Perfect Peanut Brittle

A candy thermometer is highly recommended. Temperature is extremely important when making brittle because the sugar must reach the hard-crack stage for the finished candy to become crisp.

Prepare all ingredients before beginning. Once the caramel reaches the proper temperature, the final steps happen very quickly.

Use roasted peanuts for deeper flavor. Unsalted peanuts allow you to control the salt level, although lightly salted peanuts can also create a delicious sweet-and-salty brittle.

Don’t skip the baking soda. It creates small air pockets that make the brittle easier and more pleasant to bite.

Be especially careful when working with the hot caramel. Melted sugar reaches extremely high temperatures and can cause serious burns, so keep children away from the stove during preparation.

How to Know When the Brittle Is Ready

The most accurate method is checking for a temperature of approximately 300°F (149°C) with a candy thermometer.

At this temperature, the sugar reaches the hard-crack stage. Once cooled, it should become completely firm and snap cleanly when broken.

The caramel should also have a beautiful golden-amber color without becoming excessively dark.

Serving Ideas

Serve Peanut Brittle in a large bowl as a simple after-dinner treat, or arrange the pieces on a dessert platter alongside cookies, brownies, and other homemade candies.

It also makes a wonderful edible gift. Once completely cooled, place several pieces in decorative bags, jars, or small gift boxes.

For holiday gatherings, you can prepare a larger batch and add the brittle to homemade candy trays.

Crushed peanut brittle can even be sprinkled over vanilla ice cream, chocolate desserts, or creamy puddings for an extra layer of caramel crunch.

Storage

Once the Peanut Brittle has completely cooled, store it in an airtight container at room temperature.

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

Keep the container away from moisture and humidity because brittle absorbs moisture easily, which can cause it to lose its crisp texture.

When stored properly, homemade peanut brittle can remain delicious and crunchy for several weeks.

Conclusion

Peanut Brittle proves that a handful of simple ingredients can create an incredibly satisfying homemade candy. With crunchy roasted peanuts, buttery golden caramel, and that signature crisp snap, every piece delivers a wonderful balance of sweetness and nuttiness. Whether you’re preparing it for the holidays, sharing it as a homemade gift, or simply making a batch for your family, this classic deesviral recipe is a delicious treat worth keeping in your collection.
