What is oat flour
Oat flour is simply ground oats! Itโs a whole-grain flour packed with fiber and micronutrients.
All you need is a high-speed blender to make it. You can use rolled oats or steel-cut โ weโll delve into the differences below.
How to make oat flour at home
Pour your oats into a high-speed blender and blend until they turn into a fine flour. Scrape down the sides if needed.
Itโs that simple.
In about one minute, you can have a whole container of oat flour ready to use.
The minimum and maximum amount of oats you can blend is dependent on the size of your blender. However, one cup of oats is a good starting minimum! If youโre making oat flour in bulk, ensure that your blender isnโt overfilled, so the oats process evenly.
Note
We recommend using a blender to make your oat flour, as the food processor does not finely grind the oats as much.
How to make oat flour with rolled oats
Rolled oats transform into a light, soft flour similar to the texture of all-purpose flour. However, oat flour is slightly crumblier. Since rolled oats have a flattened shape, they blend easily.
As instructed above, place your rolled oats in the blender and blend until it becomes flour (about 50-60 seconds).
How to make oat flour with steel-cut oats
Steel-cut oats take longer to blend, but they result in a higher fiber flour! They have a heartier texture than rolled oats (therefore creating a denser consistency).
To make oat flour: add the steel-cut oats to your high-speed blender. Then blend for 45 seconds and scrape down the sides if needed. Continue blending until a powder-like texture forms.
How to store oat flour
Store your oat flour in an airtight container. Place in a cool, dry area for up to 1-2 months (pantry or cabinet is best!)
- Fridge: Lasts up to 3 months.
- Freezer: Lasts up to 6 months.
Since this oat flour contains one ingredient (and no preservatives) it has a shorter shelf life. But since itโs so versatile and delicious, youโll use it all in no time!
Uses for oat flour
Itโs time to celebrate โ you can use oat flour in all your favorite baked goods! Oat flour is great in classics such as cookies, brownies, muffins, and more.
Make sure to look for recipes that specifically call for oat flour! It is not a 1:1 replacement for all-purpose flour, given the different density.

FAQs
Can you make oat flour in a food processor?
If you donโt have a blender, thatโs okay โ a food processor will work. However, you have to process the oats longer, and the texture will beย less fine.
For steel-cut oats, we recommend solely using a blender. Steel-cut oats have a tough outer shell, which can be difficult to blend into a fine flour with a food processor.
What types of oats are there?
There are six types of oats (but not all can be used to make flour):
- Oat Groats โ Whole grain oat seed (husk removed). It takes the longest to cook.
- Steel Cut โ Smaller cut pieces of oat groats.
- Rolled/Old-Fashioned โ Steamed and rolled. The flatter pieces are quicker to cook than steel cut.
- Quick Cook โ Rolled oats that are flatter and cut into smaller pieces.
- Instant โ Pre-cooked and dehydrated oats. These cook faster than quick-cook oats and are occasionally flavored. They are not recommended for baking recipes.
- Oat Bran โ Outer shell of the oat seed, underneath the husk. They have a smoother texture than rolled oats.
Is oat flour gluten-free?
Yes, as long as the oat flour is made withย certified gluten-freeย oats!
Oats are considered naturallyย gluten-freeย in several countries. However, there is a possibility of cross-contact during the production process.
The best route is to find certified gluten-free oats to make homemade oat flour (or you can find certified gluten-free oat flour at the store).
Is oat flour healthy?
Oats, and consequently oat flour, have wonderful nutritional benefits.
The National Library of Medicineย states they areย high in dietary fiberย with a balanced amino acid profile. Theyโre a great carbohydrate source thatโs high in protein.
Plus, oats contain essential micronutrients such as vitamin E, zinc, iron, magnesium, copper, and selenium.
Oats are not only delicious and versatile,ย but theyโreย nutritiousย too!
Can you freeze oat flour?
Yes! Place in an airtight container or resealable bag forย up to 6 months. Let thaw before use.
How much oat flour equals regular flour?
1 cup of oat flourย is approximatelyย 1 โ cup all-purpose.
If you want theย most accurateย ratio, you can weigh the two flours
Here are the steps:
- Place an empty bowl on a food scale (tare the scale after you place the bowl)
- Set the scale to grams
- Measure 1 cup of regular flour
- Pour the flour into the bowl
- Record the weight
Hypothetically, letโs say your 1 cup of regular flour = 120 g. That means 120 g of oat flour = 1 cup of regular flour. Easy, right?
Substituting with weight will yield accurate results, so follow weight measurements when you can!
