Why You'll Love This Recipe
Making your own oat flour is one of those little kitchen tricks that you just end up wondering why you didn't try it ages ago.
You only need one ingredient (and it takes about two minutes to make). No need to go out and buy a bag of flour when you already have oats in your cupboard.
It's also a great way to save money as rolled oats are often cheaper than ready made oat flour.
I love that I can make exactly the amount I need for a recipe. No extra bags of flour cluttering up my pantry!
Plus, you can pick how fine you want your flour. A coarse grind adds texture. A fine grind is best for most baking.
Ingredients and Equipment
You don't need anything fancy to make oat flour at home, really. Just get your oats and a blender or a food processor.
Ingredients
- Rolled Oats
Equipment
Really, that's all you need! 😲
Old-fashioned rolled oats work great for this recipe. Quick oats can also work, but I prefer rolled oats because they're easy to find and I usually have them on hand.
Steel-cut oats are much harder, so they may not grind as well in a regular blender.
Oat Flour Recipe
Equipment
Ingredients
- 1 cup Rolled Oats
Instructions
- Add the desired amount of oats to a completely dry food processor or high-speed blender.
- Start on low speed, then slowly increase to high speed as the oats begin to blend.
- Blend for a few seconds for a coarse flour or about 2 minutes for a fine flour.
- Stop every 30 seconds to stir the oats and scrape down the sides as needed.
- Once the oats reach your desired texture, stop blending to avoid overprocessing. This recipe makes approximately ¾ cup of oat flour.

Tips for Using and Storing Oat Flour
Homemade oat flour works for all kinds of recipes, but keep a few things in mind.
For baking, make the flour as fine as you can. A fine flour gives muffins, pancakes, and cookies a smoother texture. If you can still see large pieces of oats, blend a little longer.
Measure after blending. Oats and oat flour don't always measure the same by volume. If your recipe calls for a certain amount of oat flour, measure it after grinding.
Store it in an airtight container. Keep your flour in a cool, dry place away from heat and light. For longer storage, refrigerate or freeze it.
Check before using stored flour. Oats contain natural oils, so the flour can go bad over time. If it smells sour or stale, toss it.
Use the right flour for your recipe. Oat flour doesn't behave like regular all-purpose flour. It has no gluten, so baked goods may be softer or crumbly.
I like to use oat flour in recipes that already call for it. That way, I know the amount of flour and other ingredients will work well together.
You can also add a spoonful to smoothies to thicken them a little.
Frequently Asked Questions
Old-fashioned rolled oats are my favorite choice. Quick oats also work well because they're already cut into smaller pieces. Steel-cut oats are harder and may need a more powerful blender to grind into fine flour.
Oats are naturally gluten-free, but they can come into contact with wheat, barley, or rye during growing or packaging.
If you need gluten-free oat flour, use oats that are labeled certified gluten-free. Make sure your blender or food processor is clean, too.
Not in every recipe. Oat flour doesn't have gluten, which helps give many baked goods their shape and texture.
You can swap some of the all-purpose flour for oat flour, but a full swap can make baked goods too soft or crumbly.
For the best results, use a recipe made for oat flour.
One cup of rolled oats makes about ¾ cup of oat flour, though the amount can vary based on how finely you grind it.
If your recipe calls for one cup of oat flour, you may need to start with more than one cup of oats.
Yes! A food processor can also grind oats into flour.
It may take a little longer, and the flour may not be quite as fine. Stop often to scrape down the sides and check the texture.
Homemade oat flour is best when it's fresh. Store it in a sealed container in a cool, dry place and use it within a few weeks for the best taste.
You can also store it in the fridge or freezer for longer. Always check for an off smell before using it.

Can you please tell me what the conversions are for oat flour recipes? E.g. Is 1 cup of oats equal to 3/4 cup oat flour or?? I've tried finding charts that explain this conversion but haven't had any luck so far.
Thanks!

This would be great for making oatmeal bath, too.

How much oats do you put in?
Katie
You can put in however much you want. It's not an exact measurement. I would suggest filling the processor up at least 1/3 of the way.
