How to Store Oat Flour Banana Muffins

After the muffins have completely cooled, you can store them in an airtight container in the fridge for up to 5 days. You can eat them cold, but I love them reheated just slightly.

Can I Freeze Oat Flour Banana Muffins?

Yes, oat flour banana muffins are a great recipe to freeze! I love making a double batch and putting half in the freezer for later.

To freeze, once they have fully cooled, place the muffins in an airtight container or ziplock freezer bag, and freeze for up to 3 months. When you’re ready to eat them, thaw in the fridge.

Frequently Asked Questions

How do I keep oat flour banana muffins from sticking to the pan?

Before baking, make sure to grease the muffin pan well. I like to rub avocado oil into each of the cups with a napkin. The muffins also pop out much more easily if you let them fully cool before removing them from the pan.

Is oat flour gluten free?

Oats are naturally gluten free, however, some may be contaminated with gluten. If you’re sensitive to gluten, make sure to use certified gluten-free oats.

Can I make these muffins with another type of flour?

No, this recipe was created for oat flour, so you can’t use wheat flour, almond flour, or any other flour to make these muffins.

Are oat flour banana muffins healthy?

While they do have a little bit of added sugar, these muffins are primarily made with simple, healthy ingredients.

Tips for the Best Oat Flour Banana Muffins

Use older bananas – Bananas with lots of brown spots have more sugar and flavor. Sometimes I’ll use bananas that hardly look edible! Just make sure the inside isn’t black and there’s no mold.

Add walnuts or other add-ins – Walnuts are a classic addition to banana muffins! Other chopped nuts or even chocolate chips are delicious as well.

Generously grease the pan – This will help your muffins come right out without breaking or sticking.

Don’t over bake – When you insert a toothpick to check for doneness, there can still be a few moist crumbs on it.

Let cool before removing from the pan – If you can be patient, these muffins will pop out of the pan perfectly!
