I just got back from a whirlwind business trip to San Francisco and I got to hang out with alllll my blogging besties, as well as, make a few more blogging besties. I even got to stay an extra day to do some exploring thanks to the crazy winter storm the snuck up on the east coast while I was there. I did allllll the eating and drank all the wine in California so I’m glad to be back so I can start to get myself back to a regular routine….if you know what I’m saying. It was a ton of fun, I’ll try to do a recap post by the end of the week. It was an amazing trip and I was so sad to leave.  AND we have more snow coming in a couple days so it looks like I may have a ton of time to write, cook, eat and write some more. But now….I give you a recipe I’ve been sitting on for a few weeks because it’s embarrassingly easy to make and it’s not that pretty to look at but I absolutely LOVE having this in my pantry at all times. Homemade Oat Flour will soon be your new favorite, too.

This Homemade Oat Flour recipe starts with just 2 cups of either regular old fashioned oats or instant oats.  I tried to make it with steel cut oats but it ended up being pretty course and more like a cornmeal than flour so I suggest just sticking with old fashioned or instant. Place the oats in your food processor and process until powdery…..like flour.

You’ll still have a few grainy pieces and that’s totally cool…you can either sift them out or leave them in.  I think they add a nice nutty texture to baked goods but if smooth is where you’re heading a quick sifting will lift them right out.

Store your Homemade Oat Flour in an airtight container at room temperature (your pantry works well for this) until ready to use. I love to sub out the regular flour in these Oatmeal Raisin Cookies for an extra oat-y cookie or you can nix the regular flour in this pancake mix with your homemade oat flour for quick weekday Oat Pancakes! Your kids won’t even know you made the switch! And if you decide to try this recipe be sure to post a pic over on Instagram….tag @thesuburbansoapbox….and I may share on my Instastories!!!

  1. Is oat bran different than oat flour?  I use oat bran to make blueberry muffins and I can’t help but
    wonder if I can use oat flour instead?
    Thanks for all the wonderful recipes.
