Making your own oat flour at home is easy, economical and healthy. Oat flour is a great option for gluten free baking or to simply add more whole grains to your baked goods. I use this homemade oat flour every week to make waffles and pumpkin chocolate chip cookies.
Why should I make my own oat flour?
Gluten free flours such as almond, coconut, teff and all-purpose baking mixes can make gluten free baking expensive. Oat flour can be expensive too, especially if you are buying gluten free oat flour. But making your own oat flour is very economical since rolled oats are very affordable. And bonus: making oat flour takes less than 5 minutes.
Note: oats are naturally gluten free, but are often processed on the same equipment as wheat. So, if you need to avoid gluten completely, make sure to purchase gluten free oats.
How do I make homemade oat flour?
Oat flour is one of my favorite flours for gluten free baking. And it is ridiculously easy to make at home. There are two steps: add oats to a blender or food processor and grind into a flour. Done.
I've learned that grinding 2 cups of oats at a time is the perfect amount. Once you've added the oats to your blender or food processor, gradually turn it up to high and let it go for a few minutes. The finer you can grind the flour the better. I have found you get the finest grind in a blender, but a food processor will get you there too, it just takes a few minutes longer.
There is a lot of conflicting information out there about how much flour a cup of oats make, but generally one cup of oats makes one cup of flour. If you're into weighing your ingredients, a cup of oat flour is approximately 110 grams.
How do I use Oat flour?
Oats tend to absorb a lot of moisture, so oat flour usually cannot be swapped 1:1 with wheat flour in a recipe. Oat flour is often combined with other gluten free flours to achieve perfect baked goods. You can generally substitute ½ the wheat flour in a recipe with oat flour and use a gluten free all-purpose flour or almond flour to substitute the rest.
