17 Best Oat Flour Substitute
Brown Rice Flour
After milling and grinding, brown rice turns into its powder form, which is brown rice flour. Now, you may think that the same is true for white rice that undergoes a different process.
White rice’s refinement process gets rid of its husks, and makes it white in color. On the other hand, brown rice doesn’t go through refinement and maintains most of its natural components, including vitamins and nutrients like fiber. Thus, health-conscious people prefer brown rice over white rice which contains a generous amount of carbs.
So, when you’re out of oat flour, brown rice flour is a great substitute. Its flexibility allows you to use the ingredient in various dishes. It is commonly used in desserts, particularly sticky rice cake dishes, as well as in other baking recipes. To use as a substitute, use ¾ cup brown rice flour for 1 cup oat flour.

In addition, the ingredient is low in calories. There’s no need to strictly measure your intake as it is a healthy carb type that you can indulge on.
Perhaps the best coconut flour feature is its aromatic smell. When using the ingredient for your baked dishes, you don’t have to include vanilla extract anymore. A word of caution though: it is highly absorbent.

Another gluten-free oat flour alternative that is a good source of protein is amaranth flour. The ingredient is popular in the Americas where it has been used for many centuries.
While many households have this kind of flour in their pantry, it is not yet easily accessible in supermarkets and grocery stores.
Some people think that Amaranth is a nut, probably because of its nutty flavor. However, it is not. When turned into flour, amaranth is ideal for baking bread, making slurries, and thickening sauces.
While it can be an ideal option in these situations, it may not be ideal for other purposes.

Sweet Rice Flour
Sweet rice flour is ideal for use as an oat flour substitute in shrimp patties, tempura, and salmon cakes. It comes from sticky white rice, and acts a bit more like starch than flour. The ingredient can be used as a binder to add more structure to savory recipes.
In terms of flavor, you can think of sweet rice flour as rice in the form of flour. It works best when blended with other types of flour when used in baking as a 1:1 replacement ratio is not recommended. While its name suggests that it is sweet, sweet rice flour is actually not sweet.
