Learn the quick and easy method to make oat flour at home to use in baked goods (or as instant baby oatmeal!).


Oat Flour

It’s so easy and inexpensive to make oat flour at home that I never buy it at the store. And it’s such a great flour to use in baked goods to add fiber, flavor, and whole grains. It’s a staple in my pantry, is super quick to make, and is a good gluten-free flour option if you or someone in your family eats GF.

TIP: I use it in baked goods like muffins, bars, and cake, but you can also use oat flour as instant oatmeal.


Ingredients You Need

To make this homemade oat flour, all you need is oats. That’s it!


Step-by-Step Instructions

These steps will have you with oat flour in no time.

  1. Add oats to a blender.
  2. Starting on low and moving up to high, blend the oats into a flour-like consistency.
  3. Store!

Can I use a food processor?

You could use a food processor to make this oat flour, but I’d recommend a blender. The food processor won’t grind your oats into as fine of a texture.


How long can I store oat flour?

You can store your oat flour in the pantry for up to a month in an airtight container, or freeze it for up to a year in a zip top freezer bag.
