I developed this nut-free granola bar recipe to send my son to preschool with a healthier snack than many store-bought bars. It became even more valuable when I needed to eliminate common allergens from my diet while nursing our new baby. The result is a chewy, lightly sweet bar that’s sturdy enough for lunchboxes and flexible enough for many dietary needs.

These bars are intentionally simple: oats, sunflower seed butter, honey, a bit of butter and an egg to bind. You can easily customize them with mix-ins like dried fruit, seeds, or allergy-friendly chocolate chips if you don’t need to keep them strictly plain.

Ingredients & Substitutions

This version keeps the bars nut-free, gluten-free and soy-free, with no coconut oil, legumes, or corn included. If you prefer, you can make them egg-free, dairy-free or vegan with a few easy swaps.

Use the base as an oat-and-honey granola bar, or personalize with add-ins such as dried fruit, pumpkin seeds, shredded coconut, sunflower seeds, or allergy-friendly chocolate chips.

ingredients for nut-free granola bars including oats, honey, sunflower seed butter, and egg.

Oats – A mix of gluten-free quick-cook and rolled oats works well, but you can use only one type if you prefer.
Sunflower seed butter – Creamy sunflower seed butter (SunButter-style) provides protein, richness and helps bind the bars. Sweetened versions will increase sweetness.
Egg – One egg helps bind the mixture. See substitutions below for egg-free options.
Honey – Adds natural sweetness and helps the mixture hold together. Maple syrup or other liquid sweeteners can substitute.
Butter – Unsalted butter adds flavor and texture; swap for vegan butter, coconut oil or applesauce for dairy-free versions.
Salt – A small amount enhances flavor.

Substitutions

Here are simple swaps to accommodate allergies or dietary preferences:

Egg-free: Use a flax “egg”—1 tablespoon ground flaxseed mixed with 3 tablespoons water, set aside until thickened.
Dairy-free: Replace butter with a soy-free vegan buttery spread, coconut oil, or applesauce.
Vegan: Use a flax egg and swap honey for maple syrup or another liquid sweetener.
Alternate spreads: If sunflower seed butter isn’t available or its flavor is strong for you, try pumpkin seed butter or tahini as nut-free alternatives.

Recipe Tips for How to Make Them

These baked nut-free granola bars are easy and reliable. A few tips for the best results:

No long chill time: mix, bake and enjoy—no need to refrigerate before cutting.
Room-temperature storage: they keep on the counter for about a week in an airtight container.
Great texture: baking gives a crunchy bottom and chewy interior with a toasted oat flavor.

Method highlights:

Melt the honey, sunflower seed butter and butter together first so they combine smoothly.
Stir the wet mixture into the oats with the egg until everything is evenly coated—a sticky paste is expected.
Follow the two-step bake: bake the mixture in a single large square, rest briefly, cut into bars, then return to the oven for a short time to crisp the edges. This yields a better texture than cutting before any baking.

Note: sunbutter can sometimes develop a greenish tint if mixed with baking soda; this recipe does not use baking soda, so your bars should remain their natural color.

How to Store

Allow the bars to cool completely, then store them in an airtight container at room temperature. They remain chewy and fresh for 7–10 days. For longer storage, freeze the bars in a freezer-safe bag for up to 6 months. Thaw at room temperature and, if desired, warm in the oven for a few minutes to revive the chewy texture.

These bars are ideal for allergy-friendly lunchboxes, classrooms with no-nut policies, or families avoiding common allergens. They’re also simply tasty—make them because you enjoy them!

Baked Nut-Free Granola Bars

Chewy, allergen-friendly granola bars made with oats, honey and sunflower seed butter. Safe for many allergy-sensitive environments and perfect for lunchboxes or snacks.

Prep Time: 5 mins Cook Time: 20 mins Cool Time: 15 mins Total Time: 40 mins

Course: Breakfast, Lunch, Snack Cuisine: American Servings: 15 Calories: 119 kcal per bar

Ingredients

100 grams (1 cup) rolled oats
100 grams (1 cup) quick-cook oats
1/4 teaspoon fine salt
65 grams (1/4 cup) sunflower seed butter
125 grams (about 5 tablespoons) honey
28 grams (2 tablespoons) unsalted butter
1 large egg

Instructions

Preheat the oven to 325°F (163°C). Line a baking sheet or a small square baking pan with parchment paper or a silicone mat.
In a bowl, combine the rolled oats, quick-cook oats and salt.
In a microwave-safe bowl, combine the sunflower seed butter, butter and honey. Warm in 30-second intervals until melted and stir until smooth.
Add the melted mixture and the egg to the oats. Stir thoroughly until all the oats are evenly coated and the mixture is sticky.
Spread the mixture onto the prepared pan and press it evenly to a thickness of about 1/2″ (about 1–1.5 cm).
Bake at 325°F for 12–14 minutes. Remove from the oven and let it rest on the counter for 5 minutes while you increase the oven temperature to 350°F (177°C).
After 5 minutes, gently cut the slab into bars—this recipe yields about 15 snack-sized bars. Separate the bars slightly on the pan so air can circulate.
Return the pan to the oven at 350°F for 5 more minutes to crisp the edges. Remove and let cool completely on the pan before transferring to storage.
Store completely cooled bars in an airtight container for 7–10 days or freeze for up to 6 months.

Notes

You can use only rolled oats or only quick-cook oats if desired.
To make egg-free, use a flax egg: 1 tablespoon ground flaxseed mixed with 3 tablespoons water, thickened for 10 minutes.
To make dairy-free, substitute the butter with a vegan buttery spread or coconut oil.
To make vegan, replace the egg with a flax egg and swap honey for maple syrup or another liquid sweetener.
