Oat Flour Blueberry Muffins (Gluten-Free, Dairy-Free, and Low-FODMAP)

The fluffiest blueberry muffin you’ll ever know. Gluten-free, dairy-free, and FODMAP-friendly too!

I started trying to make this recipe happen about a year ago. And after many, many attempts, it’s here: oat flour blueberry muffins!

And they’re sooooo fluffy!

But seriously. I’m rather proud of my accomplishment here, considering how very unfluffy my first batch turned out. (Lesson learned: a little bit of xantham gum goes a long way.)

You can’t see from the photo here, but they rose up high just like wheat-based muffins, too. Yaaasss!And it’s good timing. Even though blueberries are definitely summer produce, I think of them as a year-round option, since they’re usually so available and so much cheaper frozen. Plus, I definitely associate baked goods with winter.

I originally wanted to make muffins that tasted just like my mother’s. I should have known better. These muffins good in a different way than Mad Bad Mommy’s are good. Which makes me a tiny bit sad. Oh, how I miss my mom’s yummy wheat-y breakfast treats.

On the other hand, I’m not only all about the taste and texture of whole grain oat flour, but it’s actually quite high in fiber and protein. Plus, if you use gluten-free oat flour, these little guys are gluten-free and dairy-free too.

Which is not to say that traditional, bakery-style muffins with all-purpose flour and butter and all the good stuff aren’t great. Definitely eat those too, if you can tolerate wheat and dairy. But even if you’re not a FODMAPer, I’d still recommend giving these treats a try for a change of muffin pace. I had mine for  breakfast this morning with cottage cheese and a clementine!Enjoy!

    These look delicious! And baked goods most definitely are associated with winter. So much comfort and coziness.

    You get PROPS. How did you get ANYTHING to be fluffy with using rice flour!? Rice flour is my nemesis. But I’m determined to let it have a rebound, so, I truly can’t wait to make these. My chickpea blueberry muffins and your oat blueberry muffins can be friends.
