Some ingredients in this recipe might not be staples in every kitchen. Light corn syrup is essential for achieving the right texture and consistency in the brittle. Additionally, a candy thermometer is crucial for ensuring the mixture reaches the correct temperature. Make sure to pick these up at the supermarket if you don't already have them.

Ingredients For Peanut Brittle Recipe
Sugar: The primary sweetener that caramelizes to form the brittle base.
Light corn syrup: Helps prevent crystallization and ensures a smooth texture.
Water: Used to dissolve the sugar and corn syrup.
Raw peanuts: Adds crunch and a nutty flavor to the brittle.
Unsalted butter: Adds richness and helps with the texture.
Baking soda: Creates air bubbles for a lighter, more brittle texture.
Vanilla extract: Adds a hint of vanilla flavor to the brittle.
Technique Tip for Making Peanut Brittle
To ensure your peanut brittle has the perfect texture, make sure to use a candy thermometer to accurately measure the temperature. Cooking the mixture to exactly 300°F (150°C) is crucial for achieving that classic brittle snap. Additionally, when you add the baking soda, be prepared for the mixture to foam up; this reaction creates the airy, crunchy texture that makes peanut brittle so delightful.

How to Store or Freeze Your Peanut Brittle
- Allow the peanut brittle to cool completely on the baking sheet before handling. This ensures that it hardens properly and is easier to break into pieces.
- Once cooled, break the peanut brittle into bite-sized pieces. Use your hands or a kitchen mallet if needed.
- Store the peanut brittle in an airtight container. This helps maintain its crisp texture and prevents it from becoming sticky.
- Place a piece of parchment paper or wax paper between layers of peanut brittle to prevent them from sticking together.
- Keep the container in a cool, dry place. Avoid storing it in humid areas, as moisture can make the peanut brittle soft and chewy.
- For longer storage, you can freeze the peanut brittle. Place the pieces in a freezer-safe bag or container, ensuring it is well-sealed to prevent freezer burn.
- When ready to enjoy, allow the frozen peanut brittle to come to room temperature before serving. This will help it regain its crispness.
- Avoid refrigerating the peanut brittle, as the moisture in the refrigerator can affect its texture and make it less crunchy.
How to Reheat Leftovers
Preheat your oven to 250°F (120°C). Spread the peanut brittle in a single layer on a baking sheet. Heat for about 5-10 minutes, or until it becomes slightly warm and pliable. Be careful not to overheat, as this can cause the sugar to melt and become sticky.
If you prefer using a microwave, place the peanut brittle on a microwave-safe plate. Heat on medium power for 15-20 seconds. Check the texture and heat for additional 10-second intervals if needed. This method is quick but requires careful monitoring to avoid overheating.
For a stovetop method, use a non-stick skillet over low heat. Place the peanut brittle in the skillet and warm it gently, flipping occasionally with a spatula. This method allows you to control the heat more precisely but requires constant attention.
If you have a toaster oven, set it to a low temperature, around 200°F (90°C). Place the peanut brittle on a piece of parchment paper and heat for about 5 minutes. This method is convenient for small batches and ensures even reheating.
To maintain the crunchiness, avoid reheating peanut brittle in a humid environment. Store any leftovers in an airtight container with a packet of silica gel to absorb moisture.
Best Tools for Making This Treat
