Peanut Brittle Recipe Without Peanuts: Nut-Free Crunchy Sweetness

This nut-free brittle delivers the same crispy, buttery sweetness as classic versions without the peanuts. I developed it for those with nut allergies or anyone wanting a different texture.

The secret is using sunflower seeds, which toast beautifully and provide that signature crunch. The process requires precise temperature control—300°F is the magic number for achieving the perfect golden amber color.

What you get is a shatteringly crunchy candy with a deep caramel flavor and satisfying texture. It breaks into irregular pieces just like traditional brittle, with none of the allergens.

Store in an airtight container for up to two weeks if it lasts that long. The recipe comes together in under 30 minutes.

Ingredients for Peanut Brittle Recipe Without Peanuts

Sunflower seeds replace peanuts for that classic crispy, buttery crunch everyone loves.

The sunflower seeds are the star here. Raw, unsalted is non-negotiable—salted will mess with the flavor balance. Whole Foods or Trader Joe’s have great bulk bins for these. I’ve tried both shelled and unshelled, but shelled gives you that perfect texture without the fuss. 300°F is your target temp, so a good candy thermometer is worth the investment.

No sunflower seeds? Pumpkin seeds work in a pinch (pepitas), but they’re a bit greener in color. Swap the vegan butter for coconut oil if you prefer. For a richer flavor, add 1 extra tsp of vanilla. Skip the baking soda if you want denser brittle, but it won’t have that signature lightness.

This keeps for 2 weeks in an airtight container at room temp. If humidity is high, add a silica packet to keep it crisp. Don’t refrigerate—it’ll get sticky. Perfect for gifting (if it survives that long).

Step-by-Step Instructions for Nut-Free Crunchy Sweetness

This method guarantees a perfect brittle with that classic snap and sweetness every time.

Step 1: Prepare the Baking Sheet and Toast the Sunflower Seeds

Line a rimmed baking sheet with the 1 sheet Parchment Paper and lightly grease it with the 1 tsp Coconut Oil. This prevents sticking and makes removal easier once the brittle sets.

In a dry skillet over medium heat, toast the 1.5 cups Sunflower Seeds for 3-4 minutes until they’re fragrant and lightly golden. Stir frequently to avoid burning. Toasting enhances their nuttiness and adds depth to the finished brittle.

Step 2: Cook the Sugar Syrup to the 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 moisten the sugar, then stop stirring to prevent crystallization.

Cook over medium-high heat until the mixture reaches 300°F on a candy thermometer. At this stage, the syrup will be clear and thick, with a hard crack consistency—test by dropping a bit into ice water; it should harden instantly and crack when bitten.

Step 3: Incorporate the Remaining Ingredients for Texture and Flavor

Once the syrup hits 300°F, quickly stir in the 0.5 cup Vegan Butter, 1 tsp Baking Soda, 2 tsp Vanilla Extract, and 0.5 tsp Salt. The mixture will foam vigorously—this is normal and creates the brittle’s airy texture.

Immediately add the toasted 1.5 cups Sunflower Seeds and stir just until combined. The baking soda reaction is time-sensitive, so work quickly to ensure even distribution before the mixture starts to set.

Step 4: Spread, Cool, and Break the Brittle

Pour the hot mixture onto the prepared baking sheet, using a heatproof spatula to spread it into an even layer about ¼-inch thick. Work fast, as the brittle will begin to harden within minutes.

Let it cool at room temperature for 30-40 minutes until completely hard and brittle to the touch. Once set, break it into pieces by hand or with a rolling pin for uniform shards. Store in an airtight container at room temperature for up to 2 weeks.

Dietary Considerations for peanut brittle recipe without peanuts

Allergy-Friendly Swaps

This recipe is naturally free from peanuts and tree nuts, making it safe for most nut allergies. I always double-check that my sunflower seeds are processed in a nut-free facility—brands like Gerbs or 88 Acres are reliable choices for severe allergies. 💪

Vegan Adaptations

The use of vegan butter and no dairy means this brittle fits plant-based diets perfectly. I prefer Miyoko’s for its rich flavor, but Earth Balance works well too. Ensure your sugar is vegan—some brands use bone char in processing.

Gluten-Free Notes

All ingredients here are inherently gluten-free, but cross-contamination can be an issue. Verify your corn syrup and baking soda are certified gluten-free if celiac disease is a concern. Karo light corn syrup is a safe bet.

Seed Alternatives

If sunflower seeds aren’t your thing, try pumpkin seeds (pepitas) for a similar crunch. They’ll give a slightly greener hue but the same satisfying snap. Toast them the same way—3-4 minutes over medium heat until fragrant.

Sugar Considerations

For a lower glycemic impact, you can substitute up to 50% of the sugar with coconut sugar, though the color and flavor will differ slightly. The texture may be slightly less crisp, but still delicious. 💡

Storage for Dietary Needs

Keep this in an airtight container at room temperature for up to 2 weeks. If humidity is a concern, add a silica packet to maintain that perfect crunch. Avoid refrigeration—it introduces moisture.
