I know better than most people how expensive baking can be, but that shouldn't stop your passion! It can seem a waste of money to buy a whole pack of something when you just need a little bit, which is why I've made this quick and easy recipe of how to make oat flour.
While oats are naturally gluten free, sometimes the process which dries and rolls them can contain gluten, so if you need gluten free oat flour, just make sure you buy oats which are certified gluten free. This definitely makes a cheaper alternative, as companies love to charge more for foods they know people with intolerance's will be forced to buy. So here's to you, gluten-free vegans, and all your baked goods!
The chances are, you will already have everything you need to make oat flour, and the only machine youll need if a blender or food processor. It's also worth mentioning that 1 cup of oats = 1 cup of oat flour, so this makes it nice and easy to use in a recipe. (1 cup oats =90g)
1 cup/90g oats (or gluten-free certified oats)
1.) Place your oats in your food processor, the smaller the container the better this will work, I've noticed that this works well if you use a smoothie blender if you're doing 1 cup or less.
2.) Pulse your oats until they form a floury powder-like constancy, this will probably only take about a minute, but don't worry if it takes longer, it all depends on the power and capacity of your blender.
3.) Give the oat flour a stir to make sure no pesky oats where stuck to the sides, if they are, just blend again for another few seconds.
4.) Store any oat flour you don't need in an airtight container in a cool dark place until you use it.
