How to Make Oat Flour

Oat flour is becoming more and more popular for home bakers. It is mild-tasting and extremely finely powdered, making it a good replacement choice for all or part of your favorite baking recipes. It is simple enough for anyone to do.
Prep Time 5 minutes
Total Time 5 minutes
Servings 1 cup


  • 1 cup old fashioned oats or rolled oats


  • Pour the rolled inside the blender and blend till floury smooth.
  • Depending on the power of your blender this process should take about 30 seconds to a minute.
  • Stop and stir in between to ensure that all the oats are evenly ground.
  • Store unused portion in an airtight container for up to 3 months.


  1. For this recipe I used the old-fashioned (rolled) oats, however, quick-cooking oats or steel-cut oats can also be used.
  2. One cup of old-fashioned or quick-cooking oats will yield approximately one cup oat flour, while one cup of steel-cut oats will yield approximately two cups of flour.
