Best Substitutes for Oat Flour
Below is a breakdown of oat flour substitute solutions and tips on how to use them in and baking!
1. Gluten-Free Flour Premix
This one is my favorite substitute for oat flour and seems to work great in baking with a similar consistency.
Gluten-free flour blends and oat flour are interchangeable and can be substituted for oat flour in a 1:1 ratio in most cases. Since some gluten-free flour blends are lighter and do not absorb as much liquid, I recommend substituting one that contains no dairy and is made with rice flours (rather than quinoa flour blends). If using glute-free flour in place of oat flour I suggest Bob’s Red Mill 1-1 Baking (affiliate link).
Play around with this one as slightly more flour (a tablespoon at a time) may be needed.
2. Almond Flour
Almond flour is slightly heavier than oat flour as it contains natural oils but makes baked goods light and fluffy and is a wonderful alternative to oat flour!
This sweet nutty flour is made from blanched almonds that are ground down into a fine flour and add lovely natural sweetness to baked goods in gluten-free baking.
Alternatively, you can use almond flour in combination with coconut flour (which is a heavier flour) for a sweeter treat. For 1 cup of oat flour, substitute it with ½ cup almond flour and ½ cup coconut flour. Or use almond flour in a 1 to 1 ratio to oat flour.
Almond flour is nuttier in flavor and has a different texture than oat flour so the taste and result will be different.
3. Brown Rice Flour
Rice flours are a commonly used gluten-free flour in baking. Brown rice flour makes a great substitute you can use instead of oat flour but not in an equal ratio.
Brown rice flour is very different than sweet rice and white rice flour. It has its husks and is less processed so it contains more fiber and nutrients and not as much sugary starch like sweet rice contains. More water may be required when using it in baking due to the high absorption of liquids.
In gluten-free baking, brown rice flour mixes best with other gluten-free flours and light starches and works well to thicken soups when used in the beginning of cooking.
To use brown rice flour in place of oat flour use ¾ cups of brown rice flour in place of each cup of oat flour.

4. Coconut Flour
Coconut flour has a beautiful aroma with natural sweetness that adds beautiful flavor to baked goods, granola bars, and desserts. It is also loaded with fiber, which may promote healthy blood sugar levels. Coconut also contains MTC oils and fats that are healthy and known to boost the metabolism. Coconut flour is a great oat flour substitute you can use in its place.
I suggest mixing coconut flour with equal amounts of almond flour. So if a recipe calls for 1 cup of oat flour, use ½ cup coconut flour combined with ½ cup almond flour. This works beautifully for cakes and cupcakes!
To use just coconut flour in place of oat flour, more liquid or less coconut flour might be needed, depending on the recipe. Coconut flour is heavy and absorbs more liquid.
What is oat flour
What exactly is oat flour and how do you use it? Oat flour is steel cut oats or old fashioned rolled oats ground in a food grinder, mill, or coffee grinder into a fine flour. It makes a wonderful substitute for flour in gluten-free baking. Make sure the oats specifically say “certified gluten-free”. Some oats when farmed and harvested are cross contaminated with wheat.
Oat flour is one of the healthiest flours to use with amazing benefits as they contain healthy carbohydrates and are an excellent source of important vitamins, minerals, fiber, protein, and antioxidants.
Tip: Oat flour in baking absorbs more liquid than some flours. When using a substitute, the alternative flour may not absorb as much liquid so play around with the texture and amounts.
