Homemade Whole-Grain Pancake Mix
1. Grind the oats in a food processor until they're chopped fine, but not a powder.
2. Put the flour, oats, and all other dry ingredients into a mixer with a paddle. Mix on slow speed, and drizzle the vegetable oil slowly while the mixer is running.
3. Store in an airtight container for up to two weeks at room temperature, or indefinitely in the refrigerator or freezer.
4. To make pancakes: Whisk together 1 cup of mix, 1 cup of buttermilk, and 1 large egg. Let the batter stand for at least 20 minutes before cooking.
5. Heat a lightly greased griddle to 350°F or medium-hot. Drop the batter onto it in 1/4-cupfuls to make a 4" diameter pancake. After about 2 minutes, flip the pancake over to finish cooking.

Frequently Asked Questions
Does this organic bread flour help me bake cleaner treats without artificial additives?
Yes. King Arthur Unbleached Organic Bread Flour is USDA Organic certified and unbleached, meaning it contains no chemical whiteners, bromate, or artificial additives — so your homemade loaves and pizza dough stay aligned with a clean-label wellness routine.
Will the higher 12.7% protein make my bread more satisfying and filling?
Yes. The 12.7% protein content develops more gluten during kneading, which produces a stronger rise, chewier crumb, and a heartier slice that tends to feel more substantial and satiating than loaves made with lower-protein all-purpose flour.
Is this flour a good fit for a mindful weekly meal-prep ritual?
Absolutely. The 5 lb resealable bag is sized to stay fresh through a week of meal-prep baking — sourdough loaves, pizza dough, dinner rolls, or sandwich bread — without going stale, supporting a low-waste, intentional kitchen routine.
Can I blend this with whole wheat flour to create healthier family loaves?
Yes. Many home bakers blend King Arthur Organic Bread Flour with whole wheat flour at a 50/50 or 60/40 ratio. The higher protein strengthens the dough, lightens the dense crumb, and still keeps the loaf organic and Non-GMO.
Does the Non-GMO verification matter for a clean-eating household?
It does. Non-GMO Project Verification means the wheat is sourced from growers who meet strict non-genetically-modified standards, giving you confidence that what you feed your family aligns with clean-eating values.
Is this flour a good choice if I want to start a sourdough starter at home?
Yes. With 12.7% protein, this flour gives your starter strong gluten development, which translates to a more vigorous rise and a crustier, more open crumb in your final sourdough loaves.
Can I use this flour for pizza night without it feeling heavy or greasy?
Yes. The high protein helps the dough develop structure so pizzas bake up with a chewy, airy crust rather than a dense, bready base — great for a lighter, more satisfying homemade pie.
Will the 5 lb bag stay fresh through several weeks of weekend baking?
Yes. The resealable bag locks out air and moisture, and unbleached flour without added preservatives typically holds its quality for several months when stored in a cool, dry pantry.
Is King Arthur a brand I can feel good about supporting as a conscious consumer?
Yes. King Arthur Baking Company has been 100% employee-owned since 2004, meaning every purchase supports the people who mill and package your flour rather than outside shareholders.
I am sensitive to additives — is this bread flour free from bleach and chemical softeners?
Yes. This flour is unbleached and free from chemical bleaching agents, so it's a more natural choice for bakers who prefer to avoid processed or chemically treated ingredients.
Is this really worth choosing over a cheaper national brand for my wellness routine?
For wellness-focused bakers, yes. You get triple certification (USDA Organic, Non-GMO Project Verified, and Kosher), heritage milling since 1790, and 12.7% protein — none of which you typically find in budget bread flours.
Will baking my own bread with this flour actually be healthier than store-bought loaves?
Generally, yes. When you bake at home, you control every ingredient — no preservatives, dough conditioners, or added sugars — and the high protein supports a satisfying, slow-digesting slice.
I worry about pesticides in flour — does organic certification actually address that?
Yes. USDA Organic certification requires the wheat to be grown without synthetic pesticides or fertilizers, which is a meaningful safeguard for households looking to reduce chemical exposure in their pantry staples.
Is the bag easy to open and reseal for an older baker with limited hand strength?
Yes. The 5 lb bag uses a simple press-to-seal closure that is easy to grip, open, and reseal without needing clips, ties, or transferring to another container.
How do I substitute this bread flour for all-purpose flour in a recipe?
You can substitute it 1:1 by volume in most yeasted recipes. For yeast-based breads, expect a slightly taller rise and chewier texture. For delicate cakes or pastries, you may want to blend it with a lower-protein flour to avoid toughness.
How long does an opened 5 lb bag stay fresh?
Stored in a cool, dry pantry in its resealable bag, the flour typically stays fresh for 6 to 12 months. For longest shelf life, transfer to an airtight container and keep it away from heat, light, and moisture.
Do I need to sift this flour before baking?
Sifting is optional. King Arthur flour is finely and consistently milled, so most bakers measure directly. Sifting can help if you want extra-light, airy doughs or are combining it with other dry ingredients.
Does this flour work with a stand mixer, bread machine, or by hand?
Yes. The 12.7% protein content performs well with any kneading method — stand mixer with a dough hook, bread machine on a dough cycle, or traditional hand-kneading. Adjust hydration as needed for very stiff doughs.
Can I use this flour to make both yeasted breads and enriched doughs like brioche?
Yes. The high protein supports yeasted loaves, and the strength also handles enriched doughs like brioche, dinner rolls, and hamburger buns, giving them a soft but structured crumb.
What comes in the bag — is the 5 lb the only size available?
The product ships as a single 5 lb resealable bag of King Arthur Unbleached Organic Bread Flour. No additional tools, yeast, or recipe cards are included.
Is the flour safe for people with common wheat allergies or celiac disease?
No. This is a wheat flour and contains gluten. It is not suitable for people with celiac disease or wheat allergies. Always check ingredient labels for personal allergen concerns.
Is this product manufactured in a facility that handles allergens like nuts or dairy?
King Arthur's manufacturing facilities follow strict allergen-control protocols. The bag is labeled pareve and dairy-free, but for severe allergies, always contact the manufacturer directly for the most current allergen information.
What is the difference between bread flour and all-purpose flour?
Bread flour has a higher protein content (12.7% here, vs. roughly 9–11% for all-purpose), which develops more gluten during kneading. This produces stronger, chewier doughs that hold their shape and rise higher in yeasted breads.
