Peanut Brittle

This Peanut Brittle isn’t just another brittle recipe — it’s the one people taste and immediately say, “Oh wow… what did you do to this?”

Where traditional brittle is hard and glassy, this version is crispy yet tender, with a light, airy, honeycomb interior that practically melts in your mouth. It shatters beautifully, but it doesn’t fight you when you take a bite — and that single difference puts it in a completely different league.

The secret? A classic Southern candy-making technique that warms the peanuts, cooks the syrup to the perfect stage, and uses baking soda at exactly the right moment to create a dramatic, foamy expansion. That aeration gives this brittle its signature lift and delicate crunch, something you’ll never find in store-bought brittle (or most homemade versions, either).

If you love homemade holiday candy, you’ll also enjoy my Easy Fudge (See’s Candy Copycat!) and Christmas Crack — both festive, foolproof treats that pair perfectly with this brittle on a holiday dessert tray. And if you’re looking for cozy classics to round out your dessert table, try my Pecan Pie or Sweet Potato Pie with Condensed Milk for a little extra Southern charm.

Let’s make something sweet together, friend. 💛

✨ Before You Begin

✨ Prep your pan before you begin. Once the candy is ready, you only have seconds to pour — the foil needs to be oiled and waiting.

✨ Use a heavy-bottomed pot. This helps prevent scorching and keeps the heat even.

✨ Warm the peanuts. This tiny detail makes a huge difference in texture — cold peanuts will cool the caramel too fast and make it dense.

✨ Don’t stir once the sugar starts boiling. Stirring after it boils can cause crystallization.

✨ The baking soda moment goes FAST. Have everything ready, and trust the process — it will foam dramatically and rise almost instantly.

Peanut Brittle Ingredients + Key Notes

This is just a quick glance at what you’ll need. For exact measurements and the full ingredient list, head down to the recipe card below.

• Peanut Oil: Used to lightly coat the foil so the brittle releases cleanly. A neutral oil is key here so it doesn’t add flavor.
• Salted Peanuts (Warmed!): Warming the peanuts keeps the sugar syrup from seizing and ensures the brittle stays light and crisp. Salted peanuts add incredible balance to the rich caramel.
• Sugar + Light Corn Syrup + Water: This trio forms the caramel base.
  • Sugar caramelizes and provides structure.
  • Corn syrup prevents crystallization and keeps the brittle tender rather than jaw-breakingly hard.
  • Water dissolves the sugar evenly and ensures smooth cooking.

• Butter: Adds richness, flavor, and a beautifully glossy finish.
• Baking Soda (The Secret!): This is what makes Georgia Pig Peanut Brittle special. When baking soda hits hot sugar syrup, it creates carbon dioxide bubbles — this aerates the candy and produces the signature honeycomb interior.

🍬 Candy Science: How the Honeycomb Happens

When baking soda meets super-hot caramel, a chemical reaction releases tiny bubbles of carbon dioxide. Those bubbles get trapped as the candy cools, creating that irresistible airy, crunchy interior.

Stirring too long destroys the bubbles — which is why the 2–3-second mix is essential!

⭐ Pro Tips

⭐ Don’t smooth the top. It destroys the honeycomb texture that makes this recipe special.

⭐ Work with purpose. Once the baking soda goes in, you have seconds before the foam settles.

⭐ Trust your nose. If the caramel starts smelling even slightly burnt, pull it from the heat and stir — this can save the whole batch.

⭐ Store it airtight. Brittle absorbs humidity like a sponge.

⭐ Break by hand. The rustic, uneven shards look beautiful in tins and bags.

How to Make Peanut Brittle 

Here’s a real quick look at how this candy comes together.

Set up your foil first — this candy moves fast once it’s ready. Give it a light coat of oil and keep it right beside the stove. Warm your peanuts in a low oven so they stay toasty and don’t cool the caramel.

Bring the sugar, syrup, and water to a boil in a heavy pot and leave it alone until it reaches 275°F. Add the warm peanuts and cook until it hits 300°F.

Now pull it from the heat, stir in the butter and baking soda, and watch the magic happen — it’ll foam up instantly. Pour it right onto the oiled foil and leave it puffed and tall. Once it cools, break it apart and enjoy the lightest, crispiest brittle you’ve ever made.

Storing + Freezing + Make-Ahead Tips

Storing

• Keep in an airtight container at room temperature for up to 2 weeks. Moisture is the enemy — avoid humid environments.

Freezing

• Not recommended. It softens when thawed and the texture is all wrong.

Make-Ahead

• This is an ideal make-ahead candy. Perfect for gifting days in advance.

✦ Frequently Asked Questions

✦ Why did my brittle come out too hard?

It likely didn’t reach 300°F. The “hard crack” stage is essential.

✦ Why isn’t my brittle airy?

Over-stirring after adding baking soda. Mix briefly, then pour immediately.

✦ Can I add vanilla?

You can, but add it before the high heat stage — adding liquid at 300°F can cause splattering.

✦ Why did my brittle get sticky?

Humidity or an unsealed container. Store airtight only.

Georgia Pig Peanut Brittle

Not your run of the mill Peanut Brittle! This Georgia Pig Peanut Brittle is tender, crunchy at the same time and has an airy, honeycomb interior. 

Prep Time15 minutes mins

Cook Time20 minutes mins

Total Time35 minutes mins

Servings: 16 people

Author: Kathleen

Ingredients

• ▢ Peanut Oil
• ▢ 1 Pound or 3 1/2 Cups Salted Peanut
• ▢ 3 Cups Sugar
• ▢ 1 Cup Light Corn Syrup
• ▢ 1/2 Cup Water
• ▢ 1 Tablespoon Plus Extra For Pan Butter
• ▢ 2 Tablespoons Baking Soda

Instructions

• Place a piece of heavy-duty aluminum foil (18 inches wide) about a yard long, shiny side up, on a work surface near the stove top.  Spread a thin layer of vegetable oil over the foil, spreading it with a paper towel.  Let is stand.
•  With additional butter to that called for, butter the sides of a 5-6 quart saucepan and set aside.
• Adjust an oven rack to the middle and preheat oven to 200 degrees.
• Place the peanuts on a rimmed baking sheet in a single level and place in the oven to heat.
• Meanwhile, place the sugar, corn syrup, and water in the buttered saucepan. With a long handled wooden spoon stir over moderate-high heat until the sugar dissolves and the mixture comes to a boil.
•  Clip a sugar thermometer to the side of the pan and let boil over moderate heat without stirring until the thermometer reaches 275 degrees.
•  Meanwhile, melt the butter in a small saucepan and set aside.
• When the candy thermometer registers 275 degrees, add the warmed peanut to sugar mixture and continue to cook, stirring frequently, until the thermometer reaches 300 degrees. (the mixture will caramelize and darken as it cooks; but if it starts to smell burnt, lift the pan quickly from the heat and stir.)
•  OKAY!! GAME ON!!  Now work QUICKLY. Remove the pan from the heat. Stir in the butter and then the baking soda (this is the SECRET of the recipe) and stir very briskly for only 2-3 seconds until the mixture becomes foamy, pale in color, and rise to the top of the pan. Do NOT wait or the foam will settle down and you will lose the honeycomb part of this brittle.  Quickly pour the foamy mixture onto the oiled aluminum foil. Do NOT smooth over the top or spread or you will deflate the brittle.
• Let stand for about 30 minutes or until cool and crisp. Then, with a thin, wide metal spatula, turn the brittle upside down and dry the bottom with a paper towel. (I did this, but personally, probably will skip this next time, where it is fairly humid and frankly didn't notice any moisture on the bottom.)
•  Break brittle into pieces and store in an airtight container.
