Oat flour has quietly become one of my most-used ingredients in the kitchen – and not just because it’s gluten-free.
It’s soft but sturdy, subtly sweet without any added sugar, and gives baked goods the kind of cozy, wholesome texture that makes you go back for a second slice. I love using it in everything from quick breads to snack bars, and the fact that it’s a whole grain full of fiber and protein? Just a very happy bonus.
But you really don’t need to buy a specialty bag from the store. If you have a blender and a container of rolled oats in your pantry, you’re already there. This is one of the easiest and most cost-effective swaps you can make in your baking – no special trips, no mystery ingredients, just a quick blitz and you’re good to go.
😍 Why You’ll Love Making Your Own Oat Flour
Even if you’re not gluten-free, oat flour is a beautiful addition to your baking. It adds a subtle, nutty sweetness and a light, tender crumb – perfect for muffins, breads, and cakes that feel just a little more nourishing. You can use it on its own in some recipes or blend it with other flours (like almond flour or all-purpose) for more structure.
It’s also a whole grain, which means you’re getting extra fiber and a boost of plant-based protein without even trying. And because oats are naturally affordable and accessible, making your own flour at home keeps things simple and budget-friendly.
Once you try it, I think you’ll find yourself reaching for it again and again – whether you’re baking for dietary reasons or just love a great texture and flavor.
🚨 Is It Really Gluten-Free?
Oats are naturally gluten-free, but if you’re baking for someone with celiac or a gluten sensitivity, make sure to use oats that are certified gluten-free. This ensures they haven’t been cross-contaminated during processing.
🗒️ What You’ll Need
Old-fashioned rolled oats – I prefer rolled oats for the best texture, but you can use quick oats in a pinch. Steel-cut oats won’t work here – they’re too hard and won’t blend evenly.
Blender or food processor – Any high-speed blender will work. I often use my Vitamix, but even a small bullet blender can get the job done.
👩🍳 How to Make Oat Flour At Home
➕ Add oats to your blender or food processor. I usually start with 1 to 2 cups at a time.
⏲️ Blend for 15-30 seconds, scraping down the sides as needed.
✋🏻 Stop when you have a fine, powdery flour – that’s it!
👏🏻 Store your oat flour in an airtight container in the pantry for up to 3 months, or longer in the freezer.
🎩 Tips and Tricks
- Don’t over-blend – you want a fine flour, not oat butter.
- Measure oat flour after blending, not before – blending changes the volume.
- For extra-fine flour, pulse and sift once blended.

👝 How to Store Homemade Oat Flour
Keep oat flour in an airtight container in a cool, dark place like your pantry for up to 3 months. For longer storage, you can freeze it – just let it come to room temperature before baking.
🧠 Common Questions
Yes, you can use quick oats, but the texture may be slightly different. Old-fashioned oats generally yield a finer flour.
Stored in an airtight container in a cool, dry place, oat flour can last up to 3 months. For extended freshness, you can store it in the refrigerator or freezer for up to 6 months.
A high-speed blender or food processor is best to get a fine, powdery texture. A regular blender can work, but you may need to blend longer and scrape the sides more often.
Oat flour works well in many recipes, but it doesn’t behave exactly like all-purpose flour. For best results, use it in recipes that specifically call for oat flour or substitute a portion of regular flour (try up to 25-30%) with oat flour for a nutritional boost.
Once the oats have transformed into a fine, powdery flour without large pieces, it’s ready. This usually takes about 15-30 seconds, depending on your blender’s strength.
Blending 1.5 cups of oats typically yields about 1.25 cups of oat flour, though this can vary slightly.
Oat flour is great for pancakes, muffins, cookies, and as a thickener in soups or smoothies. It’s also popular in gluten-free baking, but make sure your oats are certified gluten-free if needed.
Absolutely! Just multiply the oats based on your desired quantity, blend in batches, and store any extra in an airtight container.
Scraping down the sides ensures that all oats get processed evenly, which helps achieve a smooth, consistent texture without any remaining large pieces.
