Oat flour is made from rolled oats that have been ground into a fine powder. It's a great source of fiber and nutrients, and it can add a nice texture and flavor to your baked goods. But, because oat flour doesn't contain gluten, it can be a bit trickier to work with.
One of the quickest ways to substitute oat flour for regular flour is to use it in pancakes and waffles. Just replace up to 25% of the regular flour with oat flour, and you're good to go! You can also use oat flour to make delicious cookies and muffins, but you may need to adjust the liquid content to get the right consistency.
