Peanut Brittle Recipe Without Corn Syrup: Old-Fashioned Crunch With Honey Sweetness

This old-fashioned peanut brittle delivers that signature crispy crunch without corn syrup. Using honey as the sweetener creates a rich, caramelized depth that traditional versions often lack.

I developed this method after years of experimenting with natural sweeteners. The key is precise temperature control and watching for the perfect golden amber color before adding the peanuts.

The honey is non-negotiable here—local raw honey from farmers markets delivers the deepest caramelized flavor. Look for peanuts labeled raw and unsalted; Virginia or Spanish varieties work best. The baking soda must be fresh (test by mixing a pinch with vinegar—it should fizz vigorously). For the butter, Plugrá or Kerrygold are excellent choices with higher fat content for better texture.

No honey? Maple syrup at a 1:1 ratio works, though the flavor will differ slightly. Swap peanuts for cashews or almonds if preferred. Brown sugar can be omitted, but it adds a molasses note that complements the honey. Avoid salted butter—it can make the brittle unpleasantly salty. Light corn syrup is the traditional substitute, but this version skips it entirely.

Store in an airtight container with parchment between layers to prevent sticking. Keeps for 2-3 weeks at room temperature, though it’s best within 10 days. Humidity is the enemy—avoid storing near the stove or dishwasher. Freezing isn’t recommended as it can make the brittle soggy when thawed.

Step-by-Step Instructions for Peanut Brittle Without Corn Syrup

Master the technique for perfectly crisp, honey-sweetened brittle with a deep caramel flavor.

Step 1: Toast the Raw Peanuts

Spread the 2 cups Raw Peanuts in an even layer on a rimmed baking sheet. Toast in a 350°F oven for 8-10 minutes, stirring halfway through, until they’re fragant and lightly golden.

This step enhances their nuttiness and ensures they stay crunchy in the finished brittle. Watch them closely—they can go from perfectly toasted to burnt in seconds. Remove them from the oven and set aside to cool while you prepare the syrup.

Step 2: Cook the Sugar and Honey Syrup

In a heavy-bottomed saucepan, combine the 1.5 cups Honey, 1 cup Granulated Sugar, 0.5 cup Light Brown Sugar, and 0.25 cup Water. Stir just enough to combine, then stop stirring—this prevents sugar crystals from forming on the pan sides.

Cook over medium-high heat until the mixture reaches 240°F on a candy thermometer. At this stage, you’ll notice the bubbles become smaller and more uniform. Resist the urge to stir; instead, gently swirl the pan occasionally for even cooking.

Step 3: Add Butter and Peanuts for Caramelization

Once the syrup hits 240°F, add the 2 tbsp Unsalted Butter in small pieces. The mixture will bubble vigorously—that’s normal. Stir just until the butter melts completely, then add the toasted 2 cups Raw Peanuts.

Continue cooking, stirring frequently now, until the temperature reaches 290°F and the mixture turns a deep amber color. This caramelization stage is crucial for that classic brittle flavor and color. The peanuts will darken slightly as they absorb the caramel.

Step 4: Incorporate Baking Soda and Vanilla

Working quickly, remove the pan from heat and immediately stir in the 0.5 tsp Baking Soda and 1 tsp Vanilla Extract. The mixture will foam up dramatically—this is the baking soda reacting with the acidic honey, creating the brittle’s characteristic airy texture.

Stir just until fully combined, then immediately pour the hot mixture onto a greased baking sheet or silicone mat. Use a heatproof spatula to spread it into an even layer about ¼-inch thick. The mixture will still be bubbling as you spread it.

Step 5: Cool, Break, and Finish

Let the brittle cool completely at room temperature for 30-45 minutes until it’s hard to the touch and no longer warm. Don’t be tempted to touch it while cooling—it will be extremely hot and sticky.

Once fully set, break it into pieces with your hands for rustic shards, or score it with a knife for more uniform pieces. Sprinkle with 0.5 tsp Sea Salt for a sweet-salty contrast that elevates the flavor. Store in an airtight container at room temperature for up to two weeks.

Dietary Considerations for This Recipe

Vegan Adaptation

This recipe is naturally vegan as written, using only peanuts, honey, sugars, and butter. However, strict vegans should note that honey is an animal product. For a fully plant-based version, swap the honey for 1.5 cups maple syrup and the butter for vegan butter like Miyoko’s. 🌱

Gluten-Free Friendly

All ingredients in this brittle are inherently gluten-free, making it safe for those with celiac disease or gluten sensitivity. Just ensure your baking soda and vanilla extract are certified gluten-free, as some brands may process these with gluten-containing ingredients.

Also verify that your peanuts are processed in a dedicated gluten-free facility to avoid cross-contamination.

Nut Allergy Warning

This recipe contains peanuts as the primary ingredient, making it unsafe for anyone with a peanut allergy. For nut-free brittle, consider substituting sunflower seeds or pumpkin seeds in the same quantity.

The texture will differ slightly but still delivers a satisfying crunch. Always check labels on all ingredients for potential cross-contamination.

Diabetic Considerations

This is a high-sugar treat, so those managing diabetes should enjoy it in strict moderation. The honey has a lower glycemic index than granulated sugar, but it’s still concentrated sugar.

Consider making smaller batches or using sugar-free sweeteners like allulose, though the texture and caramelization may vary significantly. 💡

Low-FODMAP Option

Honey is high in fructose, which can be problematic for those on a low-FODMAP diet. Replace the honey with 1.5 cups pure maple syrup, which is lower in FODMAPs.

Also, ensure your peanuts are fresh, as older nuts can develop higher FODMAP levels. Portion control is key even with these substitutions.
