Step-by-Step Instructions

1. Prepare Your Equipment

Before starting, line a baking sheet with parchment paper or a silicone mat. This prevents the brittle from sticking and ensures easy cleanup. Have a candy thermometer ready, as precise temperature control is crucial.

2. Heat the Sugar Mixture

Golden-brown caramelized sugar in a saucepan, stirred with a wooden spoon, ready for making peanut brittle.

In a heavy-bottomed saucepan, combine sugar, corn syrup, and water. Stir over medium heat until the sugar dissolves completely. Once it starts boiling, stop stirring. Stirring at this stage can cause crystallization, leading to grainy brittle.

3. Bring to the Hard Crack Stage

Using a candy thermometer, cook the sugar mixture until it reaches 300°F, known as the hard crack stage. This is the temperature where the syrup turns into a hard, brittle texture when cooled. If you don’t have a thermometer, you can test by dropping a small amount of the syrup into cold water—it should harden instantly and snap when broken.

4. Add Butter and Peanuts

Cubes of butter melting into bubbling caramelized sugar in a stainless steel saucepan, with a bowl of peanuts in the background.

Once the mixture reaches the correct temperature, quickly stir in the butter, roasted peanuts, vanilla extract, and salt. The mixture will bubble and thicken, so work swiftly to ensure the ingredients are evenly distributed.

5. Stir in Baking Soda

Remove the saucepan from heat and immediately stir in the baking soda. The mixture will foam and expand—this is normal and creates the tiny air bubbles that give peanut brittle a lighter texture.

6. Spread and Cool

Freshly made hot peanut brittle mixture being poured and spread onto a parchment-lined baking sheet for cooling and hardening.

Pour the mixture onto the prepared baking sheet and spread it out evenly using a spatula. Work quickly, as the brittle will start to set almost immediately. Allow it to cool completely at room temperature before breaking it into pieces.

Customization & Serving Suggestions

One of the best things about peanut brittle is how versatile it can be. While the classic recipe is a time-honored favorite, you can easily modify it to suit your taste preferences or dietary needs. Below are some exciting ways to customize your peanut brittle and unique ways to serve it.

Nut Variations

Although peanuts are the traditional choice, you can substitute them with other nuts for a different flavor profile:

  • Almond Brittle: Swap peanuts for almonds for a rich, slightly sweet variation. Almonds also pair well with a touch of honey.
  • Pistachio Brittle: Adds a mild, buttery taste with a touch of green color. This version is excellent when paired with white chocolate.
  • Cashew Brittle: Creates an extra creamy texture with a delicate crunch. Cashews have a naturally buttery flavor that complements caramelized sugar beautifully.
  • Mixed Nut Brittle: Use a combination of your favorite nuts such as pecans, walnuts, and hazelnuts for a more complex flavor.
  • Seed-Based Brittle: For a nut-free alternative, try using sunflower seeds, pumpkin seeds, or sesame seeds for a delicious and allergy-friendly option.

Flavor Enhancements

Enhancing the flavor of peanut brittle can take it to the next level. Here are some ways to add an extra layer of taste:

  • Spices: A pinch of cinnamon, cayenne, or nutmeg can add warmth and depth. Cayenne, in particular, gives a spicy-sweet kick that enhances the caramel flavor.
  • Chocolate Drizzle: Melted dark or white chocolate drizzled over cooled brittle adds a luxurious touch. You can even dip half of each piece in chocolate for a more indulgent treat.
  • Sea Salt: A light sprinkle of flaky sea salt balances the sweetness with a savory kick. Salt enhances the caramel flavors and makes each bite even more satisfying.
  • Maple Syrup: Replacing part of the sugar with maple syrup gives a deep, caramel-like flavor and a slight smokiness that pairs well with nuts.
  • Vanilla Bean: Instead of vanilla extract, try using fresh vanilla bean seeds for a more intense and aromatic flavor.
  • Toffee Bits: Mixing in crushed toffee pieces can add an extra crunch and a deeper caramel flavor.

Serving Suggestions

Peanut brittle is delicious on its own, but there are plenty of creative ways to enjoy it:

  • Crushed Topping: Sprinkle crushed brittle over ice cream, yogurt, or oatmeal for added crunch.
  • Gift Idea: Wrap pieces in decorative bags or tins for homemade gifts. It makes for an excellent holiday or special occasion treat.
  • Dessert Garnish: Use small shards to decorate cakes, cupcakes, or brownies for an added textural contrast.
  • Snack Mix: Combine broken peanut brittle with pretzels, popcorn, and chocolate pieces for an irresistible mix that is perfect for movie nights.
  • Peanut Brittle Butter: Blend broken peanut brittle pieces in a food processor until smooth to create a peanut brittle spread that can be used on toast, pancakes, or waffles.
  • Peanut Brittle Bark: Layer peanut brittle with melted chocolate and nuts, then break it into pieces for a gourmet-style brittle bark.

Storage & Make-Ahead Tips

Proper storage ensures your peanut brittle stays fresh and crisp for weeks. Follow these storage tips to maintain its perfect texture.

Short-Term Storage

  • Airtight Container: Store brittle in an airtight container at room temperature to prevent moisture absorption. This keeps the brittle from becoming sticky or chewy.
  • Layering with Parchment Paper: Place parchment paper between layers to keep pieces from sticking together.
  • Cool, Dry Location: Keep brittle in a cool, dry area away from heat and humidity, which can cause it to soften.
  • Keep It Away from Sunlight: Direct exposure to sunlight can cause the sugar to degrade, leading to a change in texture.

Long-Term Storage

  • Freezing: While not common, you can freeze brittle in a sealed container for up to three months. Thaw at room temperature before serving. If freezing, wrap it tightly to prevent condensation from making it sticky.
  • Avoid Refrigeration: The fridge introduces moisture, which can make the brittle sticky and chewy.
  • Vacuum-Sealing: If you plan on storing peanut brittle for an extended period, using a vacuum-sealed bag can help maintain its crispness.

By following these storage tips, you can keep your peanut brittle fresh and ready to enjoy at any time.

Frequently Asked Questions About Peanut Brittle

Is peanut brittle good or bad for you?

Peanut brittle, like most sweets, should be enjoyed in moderation. It contains high amounts of sugar and corn syrup, which contribute to its sweet, crunchy texture. However, peanuts provide protein, healthy fats, and essential nutrients, making it a better option than some processed candies. If you’re looking for a healthier version, you can reduce the sugar or use alternative sweeteners like honey or maple syrup.

What is peanut brittle made of?

Peanut brittle is made with a combination of granulated sugar, corn syrup, water, butter, roasted peanuts, baking soda, vanilla extract, and salt. The sugar is caramelized and combined with peanuts, then spread out to harden into a crunchy, sweet treat. Baking soda helps create air pockets, making the brittle lighter and easier to bite.

Does the Dollar Tree have peanut brittle?

Yes, Dollar Tree and other discount stores often carry peanut brittle, especially around the holidays. However, the quality and taste may vary compared to homemade or premium brands. If you’re looking for the freshest and most flavorful peanut brittle, making it at home is the best option.

What’s the difference between toffee and peanut brittle?

The main difference between toffee and peanut brittle is the texture and cooking method. Toffee is made by caramelizing butter and sugar at a lower temperature, resulting in a chewy or slightly crisp texture. Peanut brittle, on the other hand, is cooked to the hard crack stage (300°F), making it much harder and more brittle. Additionally, brittle often contains baking soda, which introduces air pockets, making it lighter and crispier than dense, buttery toffee.
