By: Chris Freytag, CPT

Oat flour is a budget-friendly and delicious whole grain option for baking. We think you are going to love these wholesome and healthy oat flour banana muffins.

If you’re looking for a healthier muffin to pair with your morning cup of coffee or as an afternoon snack – try these healthy oat flour banana muffins! We love cooking with oat flour since it makes a great alternative to all purpose flour in baked goods like muffins and breads. 

Plus, oats are a whole grain and packed with fiber. In addition, they are a much more affordable gluten-free flour option for gluten-free baking when compared to almond flour or coconut flour. You can even make it yourself in 5 minutes or less!

    Ingredients You’ll Need

    top view of raw ingredients laid out on counter to make healthy oat flour banana muffins
    • Old Fashioned Oats: we like the texture of old-fashioned oats in this recipe, but you can use quick oats as well. You just want to avoid using steel cut oats as they would be too chewy for this recipe. 
    • Oat Flour: to save yourself a step when making this recipe, you can purchase pre-made oat flour in the store. However, we find it cheaper to make our own homemade oat flour – plus, it’s easy to do! 
    • Bananas: for best results, use extra ripe bananas since they are sweeter and have more intense flavor – both of which work well for baking! Plus, they are much easier to mash when they are more ripe. 
    • Monk Fruit Sweetener: we love using monk fruit in baked recipes like these muffins. This zero calorie sweetener is a more natural alternative to other zero calorie sweeteners available at the grocery store since it is extracted from the monk fruit. 
    • Baking Powder and Eggs: add lift and structure to these muffins so they get surprisingly fluffy for a healthy muffin made from oat flour.


    • Add Chocolate Chips: add ½ cup of chocolate chips 
    • Add Blueberries: instead of chocolate chips, add fresh or frozen blueberries to these healthy muffins. 
    • Add Dried Fruit: dried cranberries are one of our favorite mix-ins for these muffins. 
    • Add Nuts or seeds: we love the crunch (and healthy fats) that a handful of chopped nuts adds to these muffins. We recommend: pecans, almonds, pumpkin seeds, or walnuts. 
    • Pumpkin Muffins: instead of the banana, use 1 (15 oz) can pumpkin puree and add ½ teaspoon of pumpkin pie spice for oat flour pumpkin muffins. 
    • Gluten Free: use certified gluten-free oats and certified gluten-free oat flour to make gluten-free banana muffins.
    • Dairy Free: use dairy free chocolate chips or omit and add fruit or nuts instead.

    Mix the wet ingredients and monk fruit together: in a separate small mixing bowl, mash the bananas with a fork and add the monk fruit sweetener, eggs, and vanilla extract. Whisk well to mix. 

    Combine and add to muffin tin: add the banana mixture to the dry ingredients in a large bowl and stir well. Add the chocolate chips and stir again.

    Bake and serve: transfer batter to a muffin tin lined with paper liners. (Try not to let your batter sit out for long as it can make your gluten-free muffins more dense.) Bake for 15 minutes or just until the tops are set. If you think they aren’t done – they are!

    Don’t over bake or else they will settle and get way too hard.
