Homemade Oat Flour

Oat flour is super healthy and a great grain and gluten-free alternative to many recipes.

You only need one ingredient…oats! (Duh, right?)

Tip: Oat flour isn’t just for baking. Adding it to a bath is very soothing to your skin! 

Oat Flour Recipe

You can purchase oat flour at the store or on Amazon, but if you need some in a pinch or want to save a little cash, homemade oat flour is VERY simple to make.

If you have a high-powered blender like a Vitamix, the oats will grind up into a flour super quickly…within a few seconds! I have a Ninja blender, which is pretty powerful, but takes about thirty seconds or so to blend up into the texture that I want.

Sometimes I take a knife or spoon and move the oats around so they blend up more evenly.

Oat flour has a more rough and grainy texture than regular flour. It isn’t the best gluten-free flour alternative to use for cakes or pastry dough, but it is perfect for homemade muffins and pancakes!

Psssst: If you are gluten-free, make sure that you are buying high-quality, organic oats avoid cross contamination issues. Many companies will label their oats as gluten-free, so opt for those when possible.

You can make just as much oat flour as you need for a recipe, or make a large batch to store away in a glass jar in your pantry. I love having ingredients on hand to use and cutting down on prep work in the kitchen, so I usually make a bunch in bulk.

4 cups of rolled oats makes slightly over 3.5 cups of oat flour.

I always recommend buying organic ingredients when you can. Read: Why Should You Buy Organic?
