Peanut Brittle Recipe With Dry Roasted Peanuts: Crunchy Caramelized Sweetness

There’s nothing quite like the satisfying crunch of homemade peanut brittle made with quality dry roasted peanuts. This classic candy delivers perfectly caramelized sweetness with a texture that shatters with every bite.

The key is precise temperature control and timing. Using dry roasted peanuts ensures maximum crunch and prevents the brittle from turning chewy. The process requires patience but rewards with consistent results every time.

You’ll achieve a golden amber color and that signature snap that defines great peanut brittle. The aroma alone as it cooks will transport you to holiday kitchens and county fairs.

This recipe makes a generous batch perfect for gifting or storing in airtight containers for up to two weeks.

Ingredients for Peanut Brittle Recipe with Dry Roasted Peanuts

Pantry staples deliver that signature snap. Nothing fancy, just good stuff.

The peanuts make or break this. Dry roasted peanuts (like Planters or Sahale Snacks) give you that perfect crunch—skip raw or honey roasted. I always grab mine from Costco for the best bulk price. Look for unsalted if you want full control over the sweet-salty balance. The sugar matters too—regular granulated dissolves evenly, no need for anything fancy.

No corn syrup? Honey or agave at equal amounts (but it won’t be quite as crisp). Swap butter for coconut oil if you’re avoiding dairy. Baking soda is non-negotiable though—it’s what gives that light, airy texture. The vanilla is optional, but one teaspoon makes a difference (use the real stuff, not imitation).

Store in an airtight container at room temp—stays crisp for 2 weeks. Humidity is the enemy, so keep it dry. Great for gifting (if it lasts that long).

Step-by-Step Instructions for Peanut Brittle

Here’s the method I use for perfectly crisp, caramelized brittle every single time.

Step 1: Prepare Your Workspace and Ingredients

Before you start cooking, line a baking sheet with parchment paper and lightly grease it with some of the unsalted butter. This prevents sticking when you pour the hot mixture later. Measure out all your ingredients and have them ready to go—this process moves quickly once it starts.

I also recommend having a wooden spoon and a heatproof spatula on hand. The sugar mixture will be extremely hot, so you want tools that can handle the heat. Place the 2 cups Dry Roasted Peanuts in a bowl near your workspace for easy access.

Step 2: Cook Sugar Mixture to Hard Crack Stage

In a heavy-bottomed saucepan, combine the 2 cups Granulated Sugar, 1 cup Light Corn Syrup, and 0.25 cup Water. Stir just enough to combine the ingredients, then stop stirring—this prevents sugar crystals from forming on the sides of the pan.

Place the pan over medium-high heat and bring to a boil. Once boiling, stop stirring and let it cook undisturbed until it reaches 300°F on a candy thermometer. This is the hard crack stage, where the sugar turns a deep amber color. Watch carefully—this can take 10-15 minutes and the color changes quickly.

Step 3: Add Peanuts and Finish the Cooking

Once the sugar reaches 300°F, immediately stir in the 2 cups Dry Roasted Peanuts. The temperature will drop slightly, so keep cooking and stirring constantly until the mixture returns to 300°F. This ensures the peanuts are fully coated and the sugar is at the right consistency.

At this point, remove the pan from the heat. Quickly stir in the 2 tbsp Unsalted Butter, 0.5 tsp Baking Soda, 1 tsp Vanilla Extract, and 0.5 tsp Salt. The mixture will foam up significantly—that’s the baking soda working its magic to create a lighter texture.

Step 4: Pour, Spread, and Cool

Immediately pour the hot mixture onto your prepared baking sheet. Use your greased spatula to spread it out as thinly and evenly as possible. Work quickly but carefully—the mixture is extremely hot and will harden as it cools.

Let the brittle cool completely at room temperature for 30-45 minutes. You’ll know it’s ready when it’s hard to the touch and no longer warm. Don’t be tempted to speed this up in the fridge—it can cause the brittle to become sticky instead of crisp.

Step 5: Break and Store

Once completely cool, break the brittle into pieces by hand or with a rolling pin. The pieces will be irregular and rustic, which is part of the charm. Store in an airtight container at room temperature for up to 2 weeks.

If your kitchen is humid, you can add a silica gel packet to the container to absorb any moisture and keep the brittle extra crisp. This recipe makes enough for sharing—though I won’t judge if you keep it all to yourself!

Perfect Pairings for These Flavors

Beverage Pairings

I love serving this with a cold glass of whole milk—the creamy richness balances the intense sweetness beautifully. For adults, try a dry sherry like Fino; its nutty notes complement the peanuts perfectly. 🍷

Coffee and Tea

A strong black coffee or espresso cuts through the sugar with its bold bitterness. For tea drinkers, Earl Grey with its citrusy bergamot adds an interesting contrast that I find surprisingly delightful.

Dessert Combinations

Pair with vanilla ice cream for a hot-and-cold contrast. The brittle pieces add a wonderful crunch to chocolate pudding or cheesecake. I often sprinkle crushed brittle over my morning yogurt for a special treat.

Savory Balance

For a sophisticated pairing, serve alongside sharp cheddar cheese and apple slices. The sweet-salty combination is a classic that never fails. I always include this trio when gifting brittle during the holidays.

Holiday Serving

During the holidays, I arrange brittle pieces on a platter with dried apricots and dark chocolate chunks. The colors look festive, and the flavors work wonderfully together. ✨

Packaging Ideas

For gifts, I layer brittle in cellophane bags tied with ribbon, paired with a mini bottle of bourbon for adult friends. The vanilla notes in bourbon echo the brittle’s flavor beautifully.
