Ingredients You’ll Need

The charm of Homemade Peanut Brittle comes from its humble list of ingredients. Each one plays a vital role in creating that signature shatter, nutty aroma, and beautiful amber color that makes this treat unforgettable.

  • Sugar: The foundation for your brittle, providing structure and that caramelized warmth.
  • Corn Syrup: Prevents the sugar from crystallizing and keeps the texture smooth and glassy.
  • Water: Helps dissolve the sugar and corn syrup into a uniform syrup for perfect caramelization.
  • Salted Roasted Peanuts: The star of the show, adding a savory crunch that balances the sweet toffee.
  • Butter: Adds richness and a hint of creamy flavor that lingers with every bite.
  • Baking Soda: The secret agent! It aerates the brittle, giving that delightful snap and slightly porous texture.
  • Vanilla Extract: Rounds out the flavors and perfumes the brittle with a comforting aroma.

How to Make Homemade Peanut Brittle

Step 1: Prep Your Workspace

Have a baking sheet ready and line it with parchment paper or a silicone baking mat. Homemade Peanut Brittle comes together quickly once the sugar mixture reaches the right stage, so it’s important to have everything in place before you start cooking.

Step 2: Combine and Heat the Syrup

In a heavy-bottomed saucepan, combine the sugar, corn syrup, and water. Stir gently over medium heat until the sugar dissolves. Bring the mixture to a simmer and stop stirring, letting it bubble away until it starts turning a pale golden color.

Step 3: Add the Peanuts

Carefully stir in the roasted peanuts with a heatproof spatula. Keep cooking, swirling the pan occasionally, until the mixture reaches a deep amber hue. This is where Homemade Peanut Brittle gets its signature caramel crunch and nutty flavor.

Step 4: Finish with Butter, Vanilla, and Baking Soda

Remove the pan from heat and quickly stir in the butter and vanilla extract. Then, sprinkle in the baking soda and mix vigorously. The mixture will foam and lighten in color — that’s exactly what you want! This aeration gives the brittle its gorgeous, crisp texture.

Step 5: Pour and Spread

Immediately pour the hot candy mixture onto your prepared baking sheet. Use a greased spatula to spread it thinly and evenly. Don’t fuss over perfect edges — a rustic finish is part of Homemade Peanut Brittle’s charm. Let it cool completely until set.

Step 6: Break into Pieces

Once the brittle is fully cooled and hardened, use your hands or the back of a spoon to break it into shards. The fun is finding those various sizes and enjoying each crunchy, glimmering piece.

Garnishes

While the classic version is perfect on its own, you can take things up a notch by dusting the finished brittle with a pinch of flaky sea salt or drizzling a bit of melted chocolate across the pieces before they set. These touches highlight the sweet-and-salty magic at the heart of Homemade Peanut Brittle.

Side Dishes

Pair your brittle with a hot cup of coffee or a scoop of vanilla ice cream for a truly indulgent treat. It also makes a wonderful contrast to a simple fruit platter or a cheese board, where its crunch and sweetness balance creamy and savory flavors.

Creative Ways to Present

Wrap pieces of Homemade Peanut Brittle in clear cellophane bags tied with a colorful ribbon, tuck them into mason jars as cute gifts, or pile them high on a vintage cake stand for an old-fashioned candy shop display. It’s also a fun addition to holiday cookie trays or party favor boxes.

Make Ahead and Storage

Storing Leftovers

Keep your Homemade Peanut Brittle fresh by storing it in an airtight container at room temperature. It will stay delicious and crunchy for up to two weeks, making it ideal for gifting or snacking throughout the week.

Freezing

If you want to make a big batch ahead of time, freeze your brittle in a well-sealed bag or container, separating layers with wax paper. When you’re ready to enjoy, simply let it sit at room temperature for a few minutes — the texture and flavor will be right on point.

Reheating

Homemade Peanut Brittle is best served at room temperature, but if yours picks up a hint of softness due to humidity, you can restore its crunch by popping pieces in a low oven (about 250°F) for a few minutes on a parchment-lined tray. Let them cool before handling.

FAQs

Why did my brittle turn out sticky?

This usually means the sugar syrup didn’t reach a high enough temperature or the humidity is high. Using a candy thermometer helps ensure that classic brittle snap every time.

Can I use unsalted peanuts?

Absolutely! If you prefer to control the saltiness, unsalted peanuts are a great option. You can always sprinkle a bit of sea salt over the brittle before it sets to fine-tune the flavor.

Is Homemade Peanut Brittle gluten-free?

Yes, this recipe is naturally gluten-free, so long as all your ingredients (especially the corn syrup and roasted peanuts) are processed in a gluten-free facility. Always double-check packaging if cooking for someone with celiac sensitivity.

What kind of sugar works best?

Stick with white granulated sugar to achieve that clear, golden look and crispness that defines Homemade Peanut Brittle. Brown sugar can make the brittle softer and may introduce unwanted moisture.

Can I make this recipe without a candy thermometer?

While it’s possible to gauge readiness by watching for that deep golden color and running a cold-water “hard crack” test, a thermometer takes the guesswork out and ensures your brittle sets beautifully every time.

Final Thoughts

If you’re ready for a fun kitchen adventure and a treat that’s as rewarding to make as it is to eat, Homemade Peanut Brittle is calling your name. The crisp, buttery shards packed with roasted peanuts are always a crowd-pleaser. Give it a try and let the sweet, nutty aroma fill your kitchen — you may just find yourself with a new favorite tradition!
