Differences between oat flour and fava bean flour
The main difference between oat flour and fava bean flour lies in their source and nutritional profile. Oat flour is made from ground oats, a cereal grain that is high in fiber and complex carbohydrates. Fava bean flour, on the other hand, is made from ground fava beans, a legume that is high in protein and fiber.
Both flours are naturally gluten-free and can be a great alternative for those who need to avoid gluten. However, not all oat flours are 100% gluten-free and safe for those with celiac disease (always check your labels!).
In terms of taste and texture, oat flour has a nutty flavor and a smooth, powdery texture, while fava bean flour has a slightly earthy taste and a denser, grittier texture. Both flours can be used in a variety of recipes, but they may require different adjustments depending on the specific recipe and desired outcome.
Baking with oat flour vs fava bean flour
Oat flour and fava bean flour can be a bit trickier to work with compared to all-purpose flour, as they don’t contain gluten and won’t rise as much. I recommend adding a binding agent like xanthan gum or psyllium husk to help oat or fava bean flour hold their structure.
Both flours are also a lot more absorbent than all-purpose flour, similar to coconut flour, so they can be great choices for recipes that require a denser, more substantial texture, like muffins or bread.
However, due to fava bean flour’s stronger taste, it’s best to only use 25% fava bean flour in a gluten-free flour mix of different types of flour. In addition, make sure to cook fava bean flour since it’s not suitable for no-bake recipes!
Ingredients in oat flour vs fava bean flour
Oat flour is made by grinding oats into a fine powder, so its only ingredient should be whole grain oats.
Fava bean flour, on the other hand, is made by grinding fava beans into a fine powder. So, its 100% dehulled fava beans, which are a legume.

Oat flour vs fava bean flour storage
Both oat flour and fava bean flour should be stored in airtight containers in cool, dry places, away from moisture and heat. In my experience, oat flour remains usable for several months, but has the best quality within the first 2 months. Fava bean flour typically lasts a bit longer (up to 6 months). Always check your expiration dates to know for sure!

Nutritionally speaking, fava bean flour wins because it’s high in plant protein and fiber! However, it has a stronger earthier flavor that I like better for savory recipes like flatbreads, crackers, and pizza crusts. Oat flour has a more versatile flavor and smooth texture that is ideal for baking!
