Oat Flour FAQ

  • Is it interchangeable with all-purpose flour? No! Oat flour cannot be substituted for all-purpose flour 1:1. Search for baking recipes that specifically call for it, as an alternative. Below are a few of my favorites.
  • Is it free of gluten? Yes, provided you use oats that have been verified to be gluten-free. Although many oats are produced in facilities that also handle wheat products, oats are a naturally gluten-free food. If you must avoid gluten, look for oats that have been tested and are certified gluten-free. These oats are processed in facilities free of wheat. Bob’s Red Mill Gluten-Free Oats are good.

  • Use however you’d like in recipes!

The degree of fineness at which you grind your flour is somewhat flexible. Just blend for a little bit less time if you prefer your oats to be more coarsely ground (watching for the desired texture). If you want a very fine powder, such as all-purpose flour, mix for the longest possible period or until the desired texture is produced by your food processor.

A common substitute for white or wheat flour is oat flour. Oat flour is a godsend for those who have celiac disease or gluten sensitivity. Most people normally tolerate oats well. Above all, oat flour is healthier for you than white flour by nature.

How is Oat Flour Made?

Whole oats are processed to create oat flour. Steel cut oats can be placed right into a food processor and processed until they are fine. The majority of commercially available oat flours are stoneground, which means that they have undergone less processing than standard white flour because the oats are crushed into a fine powder by stone.

The Nutrition of Oat Flour

Whole grain foods include oat flour. Oat flour boasts the benefits of whole grains because the entire oat is used to produce it. Oat flour comes in servings of 1/4 cup. It has 110 calories, 3 grams of fiber, 4 grams of protein, and the B vitamins thiamin and riboflavin along with calcium, iron, and potassium. Overall, oat flour provides a vastly greater range of nutritional advantages than white flour.

Overall, there are many more benefits to using oat flour than drawbacks. It is vitamin-enriched, gluten-free, and contains a great amount of fiber and protein for the few calories it contains.

Technically, you are not losing out.

I find it difficult to understand why more people haven’t discovered how easy it is to make oat flour. Homemade oat flour is much more affordable and has all the advantages and qualities of store-bought oat flour. Old-fashioned oats and a blender/food processor are all you need.

I almost always use my Blendtec to produce oat flour. You undoubtedly already know that I adore preparing my favorite smoothies with my Blendtec, but it’s also by far the finest appliance for manufacturing your own flours!

Can you consume raw oat flour?

A friend on AnswerLine posed an intriguing query. A recipe for creating homemade cookie dough ice cream had been given to this person. This acquaintance was happy to read instructions in the recipe that claimed to make the flour used in the cookie dough safe by baking the flour in a preheated 350F oven for 5 minutes on a sheet pan. This friend was aware that raw flour should not be consumed. Did this actually render the flour safe, allowing for the consumption of the cookie dough in the ice cream?

There are other websites on the internet that recommend the same or similar DIY methods to get rid of potential viruses contained in wheat because edible cookie dough is currently such a hot trend. None of the websites, however, are based on research. Although it makes plausible that heating flour in an oven could remove the potential food safety concern, there are no DIY consumer instructions that are supported by research for that notion. Experts in food safety warn against using any of these do-it-yourself techniques since there is NO GUARANTEE that the flour will reach the proper 160F required to destroy food contaminants for an appropriate period of time. Additionally, baking flour may denature the protein strands, producing a less attractive end product.

Flour is not a ready-to-eat product; it is categorized as a lightly processed agricultural ingredient. Wheat can come into contact with dangerous pathogens like E. coli or Salmonella during the growth process through the excrement of wild animals. Pathogens that enter the wheat plant remain there during the milling process with the seed head. Any pathogens in the flour will typically be rendered inactive by baking temperatures when it is used to make baked goods. Uncooked flour still contains hazardous microorganisms that can be consumed and lead to disease or even worse.

So what are the safe “flour” options if one wants edible cookie dough? There are a few simple choices available:

Buy flour that has been heat-treated commercially. Our neighborhood supermarkets don’t frequently carry wheat flour that has been heated. One such brand is Page House, which is accessible online. However, the pricing is a little high.

Replace with oats or oat flour. Instead of taste, flour is utilized in dough to create structure. Oatmeal or oat flour makes a nice substitution because it is safe to consume it raw. Although it can be expensive, oat flour is simple to make by pulsing oatmeal in a food processor or blender. (About 1 1/2 cups of oat flour can be made from two cups of oatmeal.) Oatmeal is a ready-to-eat food since it is made by heating the oat grain to stabilize the oat groats and then steaming it to flatten it into oatmeal.

Eggs are the other component in cookie dough that has the potential to make it dangerous. Either use pasteurized eggs, or don’t use any at all. Eggs can also be substituted with peanut butter.

Here are two recipes that I make with my grandchildren who “love edible cookie dough.”

Help You Feel Full for Longer

You can feel fuller for longer by eating oats or foods made from oats, such as organic oat flour. This implies that you can curb your hunger, avoid mindless nibbling, and keep your weight in check.

Reduce Your Risk of Heart Disease

Both soluble and insoluble fiber are included in oat flour, which lowers your chance of getting coronary heart disease or cardiovascular disease. Therefore, including organic oat flour in your diet will aid in preventing the development of heart disease.

Helps Lower Bad Cholesterol

The wonderful thing about organic oat flour is that beta-glucans are present, which lowers harmful cholesterol. Because beta-glucan is a very sticky soluble fiber, it reduces the absorption of harmful cholesterol as it moves through the small intestine.

Normalizes Blood Pressure Numbers

Oats have been shown in studies to lower systolic and diastolic blood pressure, especially in people with mild or borderline hypertension. Therefore, oat flour made from only whole, natural oats can aid in bringing your blood pressure numbers back to normal.
