How To Substitute Oat Flour For Regular 

Oat flour is a great addition to bread and muffin recipes because it soaks up moisture and expands to make baked goods fluffy and tender. It also adds a hint of nutty flavor that I absolutely love in breakfast foods specifically.

While you can’t substitute oat flour for regular on a 1:1 ratio, you can substitute 1/4 of the total flour in the recipe with oat flour. So for example, if a recipe calls for 2c of flour, I’ll use 1 1/2c of regular or gluten-free flour blend and 1/2c of oat flour.

Is Oat Flour Gluten-Free?

Sort of. While oats themselves are naturally gluten-free, many facilities process them using the same equipment used for non-gluten-free foods. So if you or someone you cook for has Celiac’s Disease, you’ll want to choose certified gluten-free oats.

I particularly like adding oat flour to gluten-free recipes because it creates a heartier crumb. My chief complaint with many gluten-free flour blends is that the crumb is so fine that it either dries out or seems under-baked. Adding oat flour using the substitution instructions I described earlier usually solves this problem.

You’re not going to believe how simple this is.

  1. Place oats in food processor.
  2. Blend into a fine flour.

THE END.

Stupid easy, right?

Making Oat Flour Without A Food Processor

I prefer to use my food processor because it allows me to make bigger batches without stopping to scrape the sides of the bowl every two seconds. But if you don’t have a food processor, a blender can work just fine. I’ve made oat flour with a Vitamix by working in smaller batches to cut down on scraping. I found that blending 1c of rolled oats at a time yielded the fastest results with the finest grain of flour.
