With just a high-speed blender or food processor, you can transform these pantry staples into a versatile baking ingredient perfect for gluten-free recipes and more.

Quick Summary

This guide details the straightforward process of turning old fashioned oats into fine, powdery oat flour at home. It also provides essential tips, from choosing the right equipment to proper storage, to help you achieve the best results for your baking needs.

Key Points

• Start with Old Fashioned Oats: Yes, old fashioned rolled oats are an excellent choice for making homemade oat flour, and they are cost-effective.

• Use a High-Speed Blender: For the smoothest, finest flour, use a powerful high-speed blender or food processor.

• Avoid Over-Blending: Blend in short bursts to prevent the oats from heating up and becoming a clumpy texture.

• Adjust Your Recipes: Oat flour lacks gluten, so it doesn't function as a 1:1 substitute for all-purpose flour in most baking recipes.

• Store Oat Flour Properly: Keep your homemade oat flour in an airtight container in a cool, dark place, like the fridge, to maximize its shelf life.

• Use Certified Gluten-Free Oats: To ensure your oat flour is gluten-free for those with sensitivities, use oats that are specifically labeled and certified as such.

How to Make Oat Flour from Old Fashioned Oats

Making your own oat flour is an incredibly easy process that requires minimal equipment. The key is to use a powerful blender or food processor to achieve the finest possible grind. A high-speed blender will produce a smoother, more uniform flour, while a food processor may leave a slightly coarser texture, though it will still be perfectly functional for many recipes.

Step-by-Step Instructions

1. Measure Your Oats: Start by measuring the desired amount of old fashioned oats. For best results and the most consistent texture, work in smaller batches, filling your blender or food processor about halfway. It is helpful to note that 1 cup of rolled oats yields approximately ¾ cup of flour, so adjust accordingly.
2. Blend Until Powdery: Add the oats to your blender or food processor and begin blending or pulsing. The process is quick, usually taking only 30 to 60 seconds. Keep an eye on the oats as they transform into a fine powder. Be careful not to over-blend, as this can cause the oats to heat up and become clumpy.
3. Check for Consistency: Stop blending and check the consistency. Use a spatula to scrape down the sides of the container, ensuring all the oats are incorporated. If there are still larger flecks of oats, continue to blend for another 15-30 seconds. The finished product should resemble a fine, pale flour.
4. Sift for a Smoother Flour (Optional): For recipes that require a very fine, light flour, such as delicate cakes or pastries, you can sift the homemade oat flour through a fine-mesh sieve. This removes any larger, unground pieces, leaving you with a more uniform and refined flour. The larger pieces can be re-blended or used for other purposes, like thickening sauces.
5. Store Properly: Transfer your freshly made oat flour into an airtight container, such as a glass jar. Due to the natural oils in the whole grains, homemade oat flour has a shorter shelf life than highly processed white flour. Store it in a cool, dry place like a pantry for up to 3 months, or in the refrigerator for longer-term storage.

The Versatility of Old Fashioned Oat Flour

Using old fashioned oats for your flour is an excellent way to incorporate more whole grains and nutrients into your baking. Oat flour is naturally gluten-free (if certified gluten-free oats are used) and adds a mild, nutty flavor that complements many different recipes. From hearty pancakes to tender muffins, the applications are wide-ranging. However, due to the lack of gluten, it's important to remember that oat flour doesn't provide the same structure as wheat flour, which contains gluten that acts as a binding agent.

Practical Uses for Homemade Oat Flour

• Thickening Agent: Oat flour works wonderfully as a thickener for sauces, gravies, and soups, adding a subtle, nutty flavor without the heavy taste of traditional flour.
• Cookies and Muffins: Use oat flour in your favorite cookie and muffin recipes for a chewier texture and a boost of whole-grain goodness. Adding a binding agent like ground flaxseed or xanthan gum can help improve the structure.
• Breading: It can be used as a gluten-free alternative to breadcrumbs for coating chicken, fish, or vegetables before pan-frying or baking.
• Pancakes and Waffles: It creates a heartier, more nutritious breakfast than recipes made with all-purpose flour.

Conclusion

Frequently Asked Questions

Is it better to use quick oats or old fashioned oats for oat flour?

Old fashioned (rolled) oats are generally recommended for homemade oat flour because they produce a light, fluffy consistency when blended. Quick oats also work but can result in a slightly less predictable texture due to their smaller, more processed form.

How much oat flour will one cup of old fashioned oats yield?

One cup of old fashioned oats will yield approximately ¾ cup of oat flour. This ratio is helpful when measuring out your ingredients for homemade flour.

Do I need to sift homemade oat flour?

Sifting is optional and depends on the recipe. For delicate baked goods like cakes, sifting will help achieve a lighter, finer texture. For heartier items like cookies or pancakes, sifting is not necessary.

How do I store homemade oat flour?

Homemade oat flour should be stored in a sealed, airtight container, like a mason jar, in a cool, dry place. For maximum freshness, it can also be kept in the refrigerator or freezer, which helps extend its shelf life due to the natural oils in the oats.

Is homemade oat flour a 1:1 substitute for all-purpose flour?

No, it is not a 1:1 substitute. Oat flour lacks the gluten found in all-purpose flour, which provides structure. Recipes may require additional binding agents and adjustments to liquid and volume to compensate.

Can I make oat flour in a coffee grinder?

Yes, a clean coffee grinder can be used to make oat flour, especially for small batches. It's quick and effective for grinding oats into a fine powder.

Why did my homemade oat flour turn out clumpy?

Over-blending the oats can generate heat, causing the natural oils in the oats to release and clump together. To avoid this, blend in short bursts and don't fill your blender to the top.

Frequently Asked Questions

Can I use quick oats instead of old fashioned oats for flour?

Yes, you can use quick oats to make flour, but old fashioned oats are often preferred because they are less processed and tend to yield a lighter, fluffier flour.

How do I make sure my homemade oat flour is very fine?

To get the finest consistency, use a high-speed blender rather than a food processor. After blending, you can also sift the flour through a fine-mesh sieve to remove any larger, unground pieces.

What is the yield of oat flour from one cup of oats?

One cup of old fashioned rolled oats typically yields about ¾ cup of homemade oat flour. This is because the volume decreases as the oats are ground into a finer powder.

How do I substitute oat flour for all-purpose flour in a recipe?

You cannot substitute oat flour for all-purpose flour at a 1:1 ratio. Since oat flour lacks gluten, you need to use more by weight to get the correct structure. Some bakers add a binding agent like cornstarch or ground flaxseed to help.

How long does homemade oat flour last?

When stored in an airtight container in a cool, dark pantry, homemade oat flour will last for up to 3 months. Storing it in the refrigerator or freezer can extend its freshness even longer.

Can I use homemade oat flour for yeast bread?

Oat flour is not suitable for yeast bread on its own because it lacks gluten, which is essential for the bread to rise and develop structure. It is best used in recipes that do not rely on gluten, like cookies, pancakes, and muffins.

What is the best way to clean my blender after making oat flour?

To clean your blender easily, simply fill it halfway with warm water and a drop of dish soap. Run the blender for a few seconds, then rinse. This helps remove all the powdery residue and prevents it from getting stuck.
