What is oat flour

Oat flour is the by-product of blended oats (quick or rolled old fashioned oat) to a powdery form which is then incorporated into everyday cooking and even used for skincare.

Oat is an essential pantry staple in every home, it is a simple ingredient that makes delicious breakfast in form of oatmeal, this is the popular way of eating it or baked treats as oat bread, cookies and many more.

Types of oat

There are about 7 types of oats and they are basically oats in different forms, texture, flavour and their different cooking times. Here in the UK, we love and mostly use the following

Instant oat

Rolled old fashion oat

Scottish oat

Other types include

Steel-cut oats: this is extremely popular in United states

Whole oat grout: the first result after hulling raw oat, still in its whole form just like brown basmati and pure basmati rice.

Then Oat flour, there is also raw oats but this is when it is freshly harvested and this won’t be sold for consumption until it has been processed to the types mentioned above.

How to make oat flour

This is a simple and straight to the point DIY procedure, depending on the quantity you need I usually start with about 2 cups, I add it to a blender and blitz until the desired texture is achieved. 2 cups of rolled oat would yield 2 cups of oat flour

You do not need to use a high-speed blender for making oat flour, although it makes the job quicker and faster. I sometimes use my small smoothie blender which is 250W for this too when I am making a small batch.

It is a great first meal for kids as well, instead of spending a lot of money on jarred toddlers’ oatmeal that is packed full with preservatives, simply make yours at home and it keeps in the fridge for up to 48 hours

How to store

Store your DIY oat flour in an airtight container for up to one month. I prefer storing mine for few days or two weeks at most as it is easy to make and that way, the oat flour stays always fresh
