Peanut brittle is a classic treat that combines the rich, nutty flavor of peanuts with a sweet, crunchy candy base. This delightful confection is perfect for snacking, gifting, or adding a sweet touch to your dessert table. With just a few simple ingredients and a bit of patience, you can create a homemade version that rivals any store-bought variety.
When preparing this recipe, you may need to pick up a few items that aren't always found in the average pantry. Light corn syrup is essential for achieving the right texture and consistency in the brittle. Additionally, raw peanuts are preferred over roasted ones, as they cook perfectly within the candy mixture. Make sure to have a candy thermometer on hand to ensure precise temperature control.

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.
Peanuts: Adds a nutty flavor and crunchy texture to the brittle.
Unsalted butter: Adds richness and helps with the texture.
Baking soda: Creates air bubbles, making the brittle light and airy.
Vanilla extract: Enhances the overall flavor with a hint of vanilla.
Technique Tip for Making Peanut Brittle
When making peanut brittle, it's crucial to monitor the temperature closely. Use a candy thermometer to ensure the mixture reaches exactly 300°F (150°C). This is the hard crack stage, which gives the brittle its signature crunch. Stir frequently to prevent the sugar from burning and to ensure even cooking.

water - Substitute with apple juice: Apple juice can add a subtle fruity flavor while still providing the necessary liquid component.
raw peanuts - Substitute with raw almonds: Raw almonds can provide a similar crunch and nutty flavor, making them a good alternative.
unsalted butter - Substitute with coconut oil: Coconut oil can be used to achieve the same fat content and will add a slight coconut flavor.
baking soda - Substitute with cream of tartar: Cream of tartar can help achieve a similar texture by creating air bubbles in the brittle.
vanilla extract - Substitute with almond extract: Almond extract can provide a different but complementary flavor to the brittle.

How to Store or Freeze Your Peanut Brittle
Allow the peanut brittle to cool completely before storing. This ensures that it hardens properly and maintains its crisp texture.
Store the peanut brittle in an airtight container. A metal tin or a glass jar with a tight-fitting lid works best to keep moisture out.
Place a piece of parchment paper between layers of peanut brittle if you are stacking them. This prevents the pieces from sticking together.
Keep the container in a cool, dry place. Avoid storing it in the refrigerator as the humidity can cause the peanut brittle to become sticky.
For longer storage, you can freeze peanut brittle. Wrap the pieces individually in wax paper or parchment paper to prevent them from sticking together.
Place the wrapped pieces in a freezer-safe bag or container. Make sure to remove as much air as possible from the bag to prevent freezer burn.
Label the container with the date so you can keep track of how long it has been stored. Peanut brittle can be frozen for up to 2 months.
When ready to enjoy, remove the peanut brittle from the freezer and let it come to room temperature before unwrapping. This helps to avoid condensation, which can make the peanut brittle sticky.
Avoid exposing peanut brittle to direct sunlight or heat sources, as this can cause it to soften and lose its crunch.
If the peanut brittle becomes sticky or loses its crunch, you can try refreshing it by placing it in a 300°F (150°C) oven for a few minutes. Let it cool completely before storing again.
How to Reheat Leftovers
Oven Method: Preheat your oven to 250°F (120°C). Place the peanut brittle on a baking sheet lined with parchment paper. 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 too much and lose its crunch.
Microwave Method: Place a piece of peanut brittle on a microwave-safe plate. Heat on medium power for 10-15 seconds. Check the texture and repeat if necessary. This method is quick but requires careful monitoring to avoid overheating.
Stovetop Method: Use a non-stick skillet over low heat. Place the peanut brittle in the skillet and heat gently, flipping occasionally with a spatula. This method allows for even reheating but requires constant attention to prevent burning.
Toaster Oven Method: Set your toaster oven to a low temperature, around 250°F (120°C). Place the peanut brittle on a piece of aluminum foil or a small baking sheet. Heat for 5-10 minutes, checking frequently to ensure it doesn't overheat.
Warm Water Bath Method: Place the peanut brittle in a resealable plastic bag. Submerge the bag in warm water (not boiling) for a few minutes. This method gently warms the peanut brittle without direct heat, preserving its texture.
Air Fryer Method: Preheat your air fryer to 250°F (120°C). Place the peanut brittle in the basket in a single layer. Heat for 3-5 minutes, checking frequently to ensure it doesn't overheat. This method provides a quick and even reheating option.
Essential Tools for Making Peanut Brittle
Baking sheet: A flat, rectangular metal pan used to spread the peanut brittle mixture evenly and allow it to cool and harden.
Saucepan: A deep cooking pan with a handle, used to combine and cook the sugar, corn syrup, and water mixture.
Candy thermometer: A specialized thermometer used to measure the temperature of the candy mixture to ensure it reaches the correct stage (300°F or 150°C).
Spatula: A flat, broad tool used to spread the hot peanut brittle mixture evenly on the baking sheet.
Measuring cups: Tools used to measure the precise amounts of sugar, corn syrup, water, and peanuts required for the recipe.
Measuring spoons: Tools used to measure small quantities of ingredients like butter, baking soda, and vanilla extract.
Wooden spoon: A sturdy spoon used to stir the mixture as it cooks and to incorporate the peanuts.
Grease: A substance like butter or oil used to coat the baking sheet to prevent the peanut brittle from sticking.
Oven mitts: Protective gloves used to handle the hot saucepan and baking sheet safely.
Cooling rack: A wire rack used to allow air to circulate around the peanut brittle as it cools, ensuring it hardens properly.
How to Save Time on Making Peanut Brittle
Prepare ingredients in advance: Measure out sugar, corn syrup, water, and peanuts before starting to cook.
Use a non-stick saucepan: This helps prevent the sugar mixture from sticking and makes cleanup easier.
Preheat the baking sheet: Place the greased baking sheet in a warm oven (around 200°F) while you cook the brittle mixture. This helps the mixture spread more easily.
Work quickly: Once you remove the mixture from heat, immediately stir in butter, baking soda, and vanilla extract to prevent it from hardening too soon.
Use a silicone spatula: It’s heat-resistant and helps spread the brittle mixture evenly on the baking sheet.
