This is so easy to make at home, it almost sounds silly to call it a recipe. Let’s call it a tip, okay? There are no exact measurements. Basically, you make as much as you need. One cup, or 3.5 ounces of old-fashioned oats yield 3.5 ounces of oat flour. The process is simple, requiring nothing more than a food processor. Add the oats to the bowl of yours, pulse a couple of times to break the oats down a bit. Then set your food processor to the “on” position and let it go 1 to 2 minutes until you have a fine powder-like flour.
There’s an awesome recipe coming soon for Oat Soda Bread, inspired by Heidi Swanson’s forthcoming book Super Natural Every Day. Her recipe was originally for rye soda bread. I didn’t have rye flour on hand but wasn’t willing to call it a day either. So stay tuned, but first make your oat flour so you’ll be ready to go! And while oat flour is readily available, oats in bulk only cost $1.50 a pound—a big savings indeed, considering it’s so easy to make yourself. Just be sure to seek our gluten-free oats if you plan on using this flour in gluten-free cooking or baking.
