How do you substitute oat flour?

There is a long list of flour substitues that people have tried to market, but oat flour is a simple and great substitute for wheat flour. Since oat flour is gluten-free, you find some of the drawbacks that come with all gluten-free flours. Whatever you are making will be a little more delicate than it's glutenous relative, as the binding activity of the gluten is absent.

Can you substitute oat flour for wheat flour 1:1?

Yes, BUT you want to make sure to substitute the same weight of oat to flour to wheat flour, not volume. Oat flour will be a little less dense than wheat flour, so if you use the same volume of flour, you won't have enough flour for you recipe. For this you will want to use a scale to measure out your flour.

If you don't have a scale you can use an approximation. Generally you want to increase the volume by a little less than half. So if you need 1 cup of wheat flour, use 1 cup plus a not so full 1/2 cup scoop.
