How to Make Homemade Oat Flour 3 Ways

Learn how to make homemade oat flour three different ways. Grinding oats into flour is an easy way to add healthy oatmeal to your diet!

Oat flour is a healthy alternative to all-purpose flour made from wheat. It has a mild nutty flavor and creates a delicate crumb in baked goods. It can also be gluten-free when made using certified gluten-free oats.

Have you ever wondered how to make your own oat flour? Making oat flour is easy and can be done using a few different methods.

We made oat flour with old-fashioned oats and used three different methods. We used a Vitamix blender, a Cuisinart food processor, and a Braun immersion blender. Although all methods worked there was a clear winner. We've listed the pros and cons of each one!

Homemade oat flour can also be used like powdered oats for smoothies. Powdered oatmeal is a slow-digesting complex carbohydrate that makes a healthy addition to any smoothie.

Why You'll Love Oat Flour

• It is a nutritious whole grain.
• Oat flour can be easily made at home.
• It created a tender crumb in baked goods.

Recipe Ingredients

You'll need old-fashioned oats also called rolled oats. You can also use quick oats or 1-minute oats.

1 cup of old-fashioned or quick oats makes just under 1 cup of oat flour.

How to Make Oat Flour with a Blender

Add the oats to the blender and blend for about 30 seconds.

Pros

• The blender was the fastest method.
• It produced the finest grain of oat flour.
• Can make a few cups at a time.
• Easy to clean when finished.

Cons

• Results may vary with your blender. The Vitamix is a high-powered blender so it may do a better job blending than other blenders.

How to Make Oat Flour with a Food Processor

Add the oats to a food processor and run for about 1 minute. You may need to pulse a few times too.

Pros

• The flour was almost as fine as the flour with the Vitamix.
• Can make several cups at a time.
• If you have a large food processor, you could make the largest batch of oat flour out of all three small appliances.

Cons

• The food processor has the most parts to clean.

How to Make Oat Flour with an Immersion Blender

Add the oats to a tall cup and slowly move the immersion blender through the oats to grind them for about 2-3 minutes.

Pros:

• Easy clean-up.

Cons:

• Took the longest time to grind into flour.
• Most of it was ground up, but we still found a few pieces that didn't grind up.
• Can only make small amounts at a time.

The Best Way to Make Oat Flour

Although all three methods produced oat flour, the best small appliance to do the job was the Vitamix Blender. It was the fastest, easiest to clean, and made the finest flour. You can also make several cups at a time.

However, making oat flour is possible with all three appliances! If you are planning on making it often, you may want to invest in a Vitamix blender or food processor to make larger quantities than the immersion blender.

Also, we wanted to note that we planned to test our Nutrimill Grain Mill, but the manual said not to grind oats. Unfortunately, we couldn't put that to the test.

Recipe Tips & Tricks

• Results will vary based on your model of kitchen appliance.
• As the appliances run the oat flour will begin to heat up from the friction and the machines. This will cause it to look a little clumpy. Once it cools it will be nice and floury.
• Not all recipes that use all-purpose white flour can be substituted for oat flour. It is best to start with recipes that call for oat flour.

How to Substitute Oat Flour for White Flour

When substituting oat flour for white flour you can use a kitchen scale to make measure equal amounts in weight. Oat flour weighs less, so you will use more oat flour in the recipe.

According to Cookie and Kate If you don't have a kitchen scale you can multiply the white flour by 1.42 to get the desired amount of oat flour. So a recipe that calls 2 cups of white flour would use 2 x 1.42 = 2.84 cups of oat flour, which could be rounded to 3 cups of oat flour.

Storage

• Storage: Store oat flour in an air-tight container or bag.
