Peanut brittle is a classic confection that combines the rich, nutty flavor of peanuts with a sweet, crunchy caramel base. Perfect for holiday gifts or a delightful treat, this recipe is straightforward and results in a deliciously addictive snack.
While most of the ingredients for this peanut brittle recipe are common pantry staples, you might need to pick up light corn syrup and raw peanuts if you don't already have them at home. Light corn syrup helps to prevent the sugar from crystallizing, ensuring a smooth, clear candy. Raw peanuts are essential for achieving the perfect texture and flavor in your brittle.
Ingredients for Peanut Brittle Recipe
Sugar: The primary sweetener that caramelizes to form the brittle base.
Light corn syrup: Prevents crystallization and helps achieve a smooth texture.
Water: Helps dissolve the sugar and corn syrup.
Raw peanuts: Adds a nutty flavor and crunchy texture.
Unsalted butter: Adds richness and smoothness to the brittle.
Baking soda: Creates air bubbles, making the brittle lighter and easier to bite.
Vanilla extract: Enhances the overall flavor with a hint of vanilla.
Technique Tip for Making Brittle
When making peanut brittle, ensure that the sugar mixture reaches the precise temperature of 300°F (150°C) to achieve the perfect crunchy texture. Using a candy thermometer is crucial for accuracy. Additionally, work quickly when adding the butter, baking soda, and vanilla extract to avoid the mixture hardening prematurely.
Suggested Side Dishes
Alternative Ingredients
sugar - Substitute with honey: Honey provides a natural sweetness and can add a slightly different flavor profile to the brittle.
light corn syrup - Substitute with maple syrup: Maple syrup can be used to achieve a similar consistency and sweetness, though it will impart a distinct maple flavor.
water - Substitute with apple juice: Apple juice can add a subtle fruity note to the brittle while still providing the necessary liquid.
raw peanuts - Substitute with raw almonds: Raw almonds can offer a different texture and flavor while still providing the crunchiness needed in brittle.
unsalted butter - Substitute with coconut oil: Coconut oil can be used for a dairy-free option and will add a slight coconut flavor.
baking soda - Substitute with cream of tartar: Cream of tartar can help achieve a similar texture, though it may not provide the exact same chemical reaction as baking soda.
vanilla extract - Substitute with almond extract: Almond extract can add a different but complementary flavor to the brittle.

How to Store or Freeze Your Brittle
Allow the peanut brittle to cool completely before storing. This ensures that it retains its crisp texture and doesn't become sticky.
Store the peanut brittle in an airtight container. This prevents moisture from getting in and keeps the dessert fresh.
Place a piece of parchment paper between layers if you need to stack the peanut brittle. This prevents the pieces from sticking together.
Keep the container in a cool, dry place. Avoid storing it near heat sources or in humid areas, as this can cause the peanut brittle to soften.
For longer storage, you can freeze the peanut brittle. Wrap it tightly in plastic wrap or aluminum foil, then place it in a freezer-safe bag or container.
When ready to enjoy, allow the peanut brittle to come to room temperature before unwrapping. This helps maintain its texture and flavor.
Avoid refrigerating the peanut brittle, as the moisture in the fridge can make it sticky and less crunchy.
If you notice any signs of moisture or stickiness, you can refresh the peanut brittle by placing it in a preheated oven at 250°F (120°C) for a few minutes. Let it cool completely before storing again.
How to Reheat Leftovers
Preheat your oven to 250°F (120°C). Spread the peanut brittle on a baking sheet lined with parchment paper. Heat for about 5-10 minutes, just until it becomes slightly warm and pliable. Be careful not to overheat, as this can cause the sugar to melt and the brittle to lose its crunch.
If you prefer using a microwave, place a piece of peanut brittle on a microwave-safe plate. Microwave on medium power for 10-15 seconds. Check the texture and repeat if necessary, but avoid overheating to maintain the crunchiness.
For a quick stovetop method, use a non-stick skillet over low heat. Place the peanut brittle in the skillet and warm it gently, flipping occasionally until it reaches the desired temperature. This method requires close attention to prevent burning.
If you have a toaster oven, set it 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.
For an unconventional method, use a double boiler. Fill the bottom pot with water and bring it to a simmer. Place the peanut brittle in the top pot and warm it gently, stirring occasionally until it reaches the desired temperature. This method helps maintain the brittle's texture without direct heat.

Candy thermometer: A specialized thermometer used to measure the temperature of the candy mixture, ensuring it reaches the correct temperature of 300°F (150°C).
Spatula: A flat, flexible tool used to stir the mixture and to spread the hot peanut brittle evenly on the baking sheet.
Measuring cups: Tools used to measure out the precise amounts of sugar, corn syrup, water, and peanuts.
Measuring spoons: Tools used to measure out the precise amounts of butter, baking soda, and vanilla extract.
Mixing spoon: A sturdy spoon used to stir the ingredients in the saucepan.

How to Save Time on Making Brittle
Prepare ingredients in advance: Measure out sugar, corn syrup, water, peanuts, butter, baking soda, and vanilla extract before starting.
Use a candy thermometer: This ensures you reach the precise temperature of 300°F (150°C) quickly and accurately.
Grease the baking sheet ahead: Have your baking sheet ready to go before you start cooking.
Stir efficiently: Stir frequently but efficiently to dissolve the sugar and prevent burning.
Cool in the fridge: Speed up the cooling process by placing the baking sheet in the fridge.
