How to Make Peanut Brittle

Combine ingredients: In a large glass bowl, mix together the raw peanuts, granulated sugar, salt, and light corn syrup until well coated. This blend will create your candy base.
Microwave: Place the bowl in the microwave and heat on high (1650 watts) for 4 minutes and 45 seconds. If you have a lower wattage, make sure to adjust the time accordingly to avoid burning.
Stir mixture: Carefully remove the bowl and stir the mixture gently. Return it to the microwave for another 4 minutes and 45 seconds. This helps ensure even cooking and prevents clumping.
Add butter: Take the bowl out and immediately add the unsalted butter. Stir until fully melted and combined into the mixture, creating richness and flavor.
Heat to temperature: Microwave the mixture once more, this time until it reaches 300°F. This should take about an additional 4 minutes and 45 seconds. A candy thermometer is ideal for accuracy!
Incorporate baking soda and vanilla: Stir in the baking soda and vanilla extract; the mixture will foam and turn a light color. This step further improves texture and flavor.
Pour and spread: Quickly pour the hot candy mixture onto two non-greased baking sheets. Use a spatula to spread it into a thin layer for maximum crunchiness.
Cool: Allow the peanut brittle to cool for at least 30 minutes before breaking it into pieces. Patience is key here for achieving that perfect snap!

Optional: Drizzle with melted chocolate for a delightful twist!

Expert Tips for Peanut Brittle

Watch the Microwave: Pay close attention while microwaving to prevent burning; sugar gives off a strong smell before it burns, which could spoil your batch.
Know Your Wattage: Always adjust the microwave times according to the wattage of your microwave to ensure the mixture reaches the perfect temperature for peanut brittle.
Cool Completely: Allow the brittle to cool completely before breaking it apart; this step is essential for achieving that irresistible, crunchy texture.
Stir Gently: When mixing ingredients, stir gently but thoroughly to avoid clumping and ensure an even distribution of flavors and textures.
Flavor Variations: Don’t hesitate to experiment with flavors; try adding a sprinkle of sea salt or a drizzle of chocolate right before it sets for a unique twist on classic peanut brittle!

How to Store and Freeze Peanut Brittle

Room Temperature: Store peanut brittle in an airtight container at room temperature for up to 6-8 weeks. This will keep it fresh and crunchy!
Fridge: If you prefer cooler conditions, you can refrigerate it. Just remember to place it in an airtight container to prevent moisture. It will last about 2-3 weeks in the fridge.
Freezer: For longer storage, peanut brittle can be frozen. Wrap individual pieces in plastic wrap and place them in a freezer-safe bag for up to 3 months.
Reheating: If frozen, let the peanut brittle thaw at room temperature for about 30 minutes before enjoying. The crunchy texture is best appreciated fresh!

Peanut Brittle Variations

Chocolate Drizzle: Add melted chocolate on top just after pouring onto baking sheets for a rich, decadent touch. This sweet addition takes your peanut brittle to a new level of indulgence.
Spicy Kick: Sprinkle in a dash of cayenne pepper or chili powder with the peanuts for a surprising heat. The contrast of spicy and sweet will have your guests asking for more.
Nutty Variety: Swap out raw peanuts for mixed nuts like cashews or almonds. Each nut will bring its unique crunch and flavor, making every bite an adventure.
Maple Flavor: Replace granulated sugar with maple sugar for a hint of maple sweetness. This change imparts a warm, cozy flavor reminiscent of autumn treats.
Cinnamon Delight: Stir in a teaspoon of cinnamon to the mixture before microwaving for a warm, aromatic twist. The familiar scent of cinnamon will evoke cherished holiday memories.
Coconut Infusion: Add unsweetened shredded coconut during the last minute of cooking for a tropical flair. The coconut will lend a beautiful chewiness alongside the classic crunch.
Herb-Infused: Experiment with rosemary or thyme for an unexpected savory note. Their aromatic qualities will transform the candy into a gourmet treat perfect for sophisticated gatherings.

Barb’s Famous Microwave Peanut Brittle Recipe FAQs

What type of peanuts should I use for peanut brittle?
Absolutely! Raw peanuts are ideal because they provide that perfect crunch and nutty flavor. If you’re looking for a twist, you can experiment with other nuts like almonds or cashews, but be sure to adjust the cooking times as their moisture content may vary.

How do I store homemade peanut brittle?
To keep your peanut brittle fresh for up to 6-8 weeks, store it in an airtight container at room temperature. I often recommend using parchment paper between layers to prevent sticking. If you’re in a humid area, this will save you from any unappetizing clumping!

Can I freeze peanut brittle?
Yes, you can! To freeze peanut brittle, individually wrap pieces in plastic wrap and then place them in a freezer-safe bag. This way, you can enjoy your sweet treat for up to 3 months. When you’re ready to enjoy, just let it thaw at room temperature for about 30 minutes for the best texture.

What should I do if my peanut brittle is too hard?
If your peanut brittle turns out too hard, it’s likely due to overcooking. Make sure to monitor the temperature closely; it should reach 300°F but not exceed that point. If it’s already made and still too hard, you can try breaking it into smaller pieces, which may make it easier to munch on.

Is peanut brittle safe for dogs?
It’s best to be cautious! While peanuts themselves are generally safe for dogs in small amounts, the sugar and salt in peanut brittle can be harmful to our furry friends. Always double-check ingredients and consider offering them plain peanuts instead; they’ll love you for it!

Can I adjust the sweetness of my peanut brittle?
Indeed! You can tweak the sweetness a bit by adjusting the amount of sugar. Just keep in mind that reducing sugar too much may alter the texture and sweetness balance. I typically find that Barb’s method offers just the right blend of sweet and salty, creating that irresistible flavor that everyone enjoys!
