Nut-Free Brittle Recipe: Gluten-Free & Dairy-Free
The honest verdict
Nut-Free Brittle Recipe
Classic brittle gets its name and character from the crunchy candy matrix around nuts — typically peanuts or cashews. Removing nuts and replacing them with seeds or puffed grains creates a structurally identical brittle that is peanut-free and tree-nut-free. The candy base of sugar, corn syrup, and a small amount of fat is naturally gluten-free and can be made dairy-free by substituting coconut oil or vegan butter for traditional butter. This recipe is designed to be free from peanut, tree nut, dairy, and gluten — the four allergens that make traditional brittle inaccessible for many. Sesame seeds are a possible add-in but are noted as an allergen swap, not the default, since sesame is the 9th US major allergen as of 2023. Always confirm that seed ingredients are manufactured in a dedicated nut-free facility to avoid processing cross-contact.

Key facts
Traditional peanut brittle and nut brittles are unsafe for both peanut and tree-nut allergies — seed-based brittle removes all nut ingredients.
Sesame became the 9th major US food allergen in January 2023 — sesame seeds are not a suitable nut-free swap for multi-allergen-free recipes.
Processing cross-contact from shared seed/nut manufacturing facilities is the most common residual allergen risk in nut-free seed products — always check facility statements.
Ingredients & what it's free from
Everything that goes into nut-free brittle recipe, and the major allergens this version leaves out. Swap any ingredient with your own trusted, allergen-safe brand and always read labels — formulations differ.
Ingredients
- 1 cup granulated sugar
- 1/2 cup light corn syrup
- 1/4 cup water
- 1 cup sunflower seeds (raw or lightly roasted, unsalted — confirmed nut-free facility)
- 1 tablespoon refined coconut oil or vegan butter (dairy-free)
- 1 teaspoon vanilla extract
- 1 teaspoon baking soda
- 1/4 teaspoon fine salt
Free from
- Peanut
- Tree Nut
- Dairy
- Gluten
Free-from as written — verify each ingredient label yourself, since brands reformulate and cross-contact varies by supplier.
Allergen-safe ingredient swaps
Swap out an ingredient to fit another allergy without losing the result. Each swap notes why it works so you can adapt it to what you have on hand.
Sunflower seeds in place of peanuts
Sunflower seeds are not a nut — they are a seed and are safe for peanut and tree-nut allergies when produced in a nut-free facility. They provide a similar crunch, fat content, and bite to peanut brittle when embedded in the hot candy base. Lightly roasting sunflower seeds before adding enhances the toasty flavor.
Pumpkin seeds (pepitas) in place of cashew or pecan brittle
For those seeking a larger-kernel brittle with more visual presence, pumpkin seeds substitute well for cashew or pecan pieces. They have a mild, buttery flavor when caramelized and no nut allergen concerns. Use hulled green pepitas for best results.
Puffed rice or puffed millet in place of nut clusters
Puffed rice or millet creates a lighter, more delicate brittle — similar to a rice crispy candy base — that is free from seeds as well as nuts. This is the broadest allergen-free option when seed allergies also apply. Ensure the puffed grain is certified gluten-free if wheat cross-contact is a concern.
Refined coconut oil or vegan butter in place of dairy butter
Traditional brittle uses butter at the end of cooking to add richness and help the baking soda foam for airiness. Refined coconut oil or vegan butter substitutes directly without introducing dairy. Refined coconut oil has a neutral flavor; unrefined adds mild coconut taste. Note: if coconut is a concern (it is classified as a tree nut by FDA, though most tree-nut-allergic individuals tolerate coconut), substitute with a soy-free vegan butter instead.

Cross-contact & severe allergies
A “free of” mark on the grid above means the allergen isn't an ingredient — it doesn't mean the item was made in an allergen-free kitchen. Two things matter most:
If your allergy is severe
If you have a severe or anaphylactic allergy, treat no fast-food item as guaranteed safe. Tell the staff about your allergy, ask how the item is prepared, and carry your epinephrine auto-injector every time. When in doubt, don’t risk it.
This guidance is general and can't account for how any single location prepares your food. The restaurant's staff and official allergen menu are the final word — when in doubt, ask, or choose something else.
❓Frequently Asked Questions
Traditional brittle is primarily defined by its nut content — peanut brittle uses peanuts; other varieties use cashews, pecans, or almonds. All of these are peanut or tree nut allergens. The candy base itself (sugar, corn syrup, butter) is nut-free, but the nuts are a core ingredient, not an optional topping. Nut-free brittle simply replaces the nuts with seeds or puffed grains while keeping the same candy-making process.
Yes. The candy base — sugar, corn syrup, water, and a small amount of fat — contains no wheat or gluten. The gluten risk comes from two sources: baking soda (confirm it is certified gluten-free, since some are processed in wheat-containing facilities), and any seeds or puffed grains added as the nut substitute (confirm they are certified gluten-free if cross-contact matters). The vanilla extract should also be confirmed as gluten-free; most are, but check the label.
You can, but sesame is the 9th major US food allergen as of 2023 — substituting sesame seeds would make the brittle nut-free but no longer sesame-free. For individuals avoiding both tree nuts and sesame, sesame seeds are not a suitable substitute. Sunflower seeds or pumpkin seeds are preferred as they add no new major allergens to the recipe.
Sunflower seed brittle has a similar overall experience to peanut brittle — crunchy, caramelized candy with a seed-studded texture. The flavor is slightly different: sunflower seeds have a mild, earthy note rather than the distinct peanut flavor. Adding a touch of vanilla extract and a sprinkle of salt at the end enhances depth. The candy base itself (caramelized sugar) provides most of the characteristic brittle flavor.
Source your sunflower or pumpkin seeds from a brand that is produced in a dedicated nut-free facility — the seed packaging should state 'produced in a peanut-free and tree-nut-free facility' or equivalent language. At home, use dedicated cookware, candy thermometers, and utensils that have not been used with peanut or nut products without thorough cleaning. Candy pans are particularly difficult to fully decontaminate for trace proteins — using a dedicated pot and baking sheet reduces risk for anaphylaxis-level nut allergy.
