Understanding King Arthur Flour and Dairy Ingredients
King Arthur Baking Company has a long-standing reputation for quality flour and baking products. For those with dairy allergies or following a vegan diet, understanding which of their many products are safe is essential. The good news is that their core flour products—like the Unbleached All-Purpose Flour and Bread Flour—are inherently dairy-free. They are made from simple ingredients: wheat and enzymes. The company's allergen program page provides helpful information, stating that their Signature Flours, packaged in paper bags, do not have any of the U.S. top 9 allergens, including milk, added to them.
Products Free from Dairy Ingredients
For bakers needing to avoid dairy, a large portion of the King Arthur lineup is suitable. These products are typically a safe bet, though confirming the latest ingredient list is always wise.
- Unbleached All-Purpose Flour: The quintessential pantry staple is made simply from wheat and is naturally dairy-free.
- Unbleached Bread Flour: Higher in protein for lofty yeast breads, this is also a safe choice for dairy-free baking.
- Gluten-Free All-Purpose Flour: This non-dairy blend uses rice flour, brown rice flour, tapioca starch, and potato starch as its base.
- Measure for Measure Flour: An easy gluten-free substitute, its ingredients also confirm it is dairy-free.
- 100% Whole Wheat Flour: Made from 100% hard red whole wheat, this flour contains no dairy.
- '00' Pizza Flour: This special-purpose flour is milled from wheat and is dairy-free.
- Organic Flours: The organic versions of King Arthur's flours also adhere to a dairy-free ingredient profile.
Checking Baking Mixes and Other Products
While the pure flours are generally safe, the story changes when looking at King Arthur's wide range of baking mixes. These products contain pre-blended ingredients that might include dairy in the form of milk powder, whey, or buttermilk. Examples of mixes to scrutinize include pancake mixes, biscuit mixes, and cake mixes. While the company offers dairy-free baking recipes and some mixes explicitly labeled for dairy-free use, cross-checking the specific product packaging is the only way to be 100% certain.
How to Verify for Dairy
If you have a severe dairy allergy, checking every package is non-negotiable. King Arthur Baking Company offers several resources to help:
- Ingredient List: The ingredient panel on the product packaging is the most reliable source. Scan for common dairy terms like milk, whey, butter, casein, or buttermilk powder.
- Allergen Statement: The company often provides clear allergen statements, either on the packaging or on its website. Look for phrases like "contains milk" or warnings about cross-contact.
- Product-Specific Information: Visit the King Arthur Baking website for detailed information on individual products. Their product pages and downloadable packaging PDFs often contain the most current and specific ingredient details.

Conclusion: The Bottom Line on Dairy-Free Baking
Most standard King Arthur flours are dairy-free, making them safe for a vegan or dairy-free diet. This includes their all-purpose, bread, and whole wheat varieties. Their gluten-free flours are also explicitly labeled non-dairy. However, diligence is required when purchasing baking mixes. These products often contain complex pre-mixed ingredient lists that can hide milk or milk-derived components. For peace of mind and safety, always read the ingredient label of any King Arthur product, especially their mixes, before use. Consulting their official website's allergen program is the best practice for bakers with allergies.
Final Recommendations for Dairy-Free Bakers
When baking dairy-free, relying on King Arthur's plain, unprocessed flours is a very reliable strategy. For recipes that traditionally call for milk, King Arthur's blog provides excellent resources for substituting dairy ingredients with plant-based alternatives like soy, almond, or coconut milk. By combining a dairy-free King Arthur flour with dairy-free substitutions, you can confidently create delicious baked goods without any concerns about dairy.
Checking for Cross-Contamination
For individuals with severe dairy allergies, cross-contamination is a valid concern. While King Arthur outlines its allergen program on its website, it's important to understand the details. Their allergen statement for Signature Flours says no top 9 allergens are added to the products in paper bags, and these products are made in a facility where wheat is the only top 9 allergen in production. However, manufacturing practices can change, and it is always safest to consult the company directly for the most current information regarding cross-contact prevention if you have a life-threatening allergy.
The Role of Ingredient Simplicity
One of the main reasons King Arthur's staple flours are dairy-free is their simple ingredient profile. All-purpose flour, for example, is milled from wheat with minimal additives. The absence of complex ingredient lists significantly reduces the risk of accidental dairy inclusion. This simplicity is a major advantage for bakers who need to control every component of their recipe for dietary reasons. For mixes, where the goal is convenience, more ingredients are naturally included, which is where dairy products are most likely to appear.
