Ingredients

2 cups oats old-fashioned, quick cooking, or *steel-cut

Instructions

Fill a blender or food processor about halfway with oats.
Blend until the oats turn into flour-like consistency, with no whole oats. This could take anywhere from 30-60 seconds. (I usually repeat this a second time for extra smooth flour.)
Use oat flour immediately for baking, or store for later use.

Notes

*Steel-cut oats will yield four cups of oat flour.

RECIPE NOTES

Oat flour doesn't contain gluten, so you may need to add other ingredients (like baking powder/soda in combination with apple cider vinegar or lemon juice) to help create a light and fluffy texture.
I've developed many recipes specifically for oat flour, so if you follow these recipes, you can be sure the final results will turn out! (Linked above!)
Remember that if you want to keep a recipe gluten-free, you need to by certified gluten-free oats for making your own oat flour.
I prefer using old-fashioned oats for homemade oat flour. If you use steel-cut oats, note that it will make double the amount of oat flour.
