Easiest Homemade Oat Flour

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.

Tips for Making the Best Oat Flour

• Store for 1 month in an airtight container at room temperature or up to 1 year in a zip top freezer bag in the freezer.
• You can use a food processor, though it will not grind into as fine of a texture.
• To make gluten-free, start with certified gluten-free rolled oats.
• Use as instant oatmeal for babies or toddlers by mixing with a 2:1 ratio of hot water to oats. Add cinnamon or fruit as desired.
• Use in recipes like Healthy Breakfast Bars, Vanilla Oat Smash Cake, Blueberry Banana Muffins, and Soft-Baked Granola Bars.
