The oat flour carrot muffins I shared last month turned out so well I couldn’t wait to make another oatmeal muffin. These gluten free banana oat muffins are soft and tender, lightly sweetened with maple syrup, filled with wonderfully juicy blueberries, and are perfectly crunchy from the granola on top. Oatmeal banana muffins are a gluten-free, dairy-free, egg-free breakfast or snack made with whole food ingredients. And they are absolutely delicious.

These muffins don’t have any refined flours or wheat, just blended whole grain oats. Oats are a good source of vitamins, minerals, antioxidants, and fiber. They are also higher in protein and fat than many other grains. I make my own oat flour by blending certified gluten free oats in the blender. One question I always get asked:

Are oats gluten free?

Yes and no. Oats are naturally gluten free, but are often contaminated during processing. Always look for certified gluten free oats if you have an allergy or intolerance. In this recipe I’ve used certified gluten free oats as well as certified gluten free Honey Nut granola from Back to Nature. Another interesting fact I learned recently is that oats cannot be labeled gluten free in Australia. Here’s more information on why. Some people with gluten sensitivities also cannot tolerate oats. If that’s you, you’ll need to skip this recipe or substitute your favorite gluten free flour blend.

How to Make Oat Flour

Oat flour can be purchased at many natural foods stores, but why not just make it? Add the oats (I used old fashioned but quick oats are fine too) to a blender or food processor and blend until very finely ground into a flour. This takes about 20 seconds in my Vitamix blender. I add the other dry ingredients like baking soda and baking powder in with the oats because it’s just so quick and easy.

How to Make Gluten Free Banana Muffins

Like most banana bread and muffin recipes, this one starts with three very ripe bananas. Banana muffins are a great solution for bananas that are just past their prime. The bananas get smashed up with a fork, which is a fun task for kids to help with. I tried making this recipe entirely in the blender by tossing the bananas in with the other ingredients and found they the muffins didn’t get quite as fluffy, so we’re sticking keeping the wet and dry ingredients separate until the end. Healthy ingredients like mashed bananas, flax meal, and maple syrup get mixed together for homemade gluten free banana muffins.

Flax meal, which works as a binder and adds nutrition, maple syrup, coconut oil or melted butter, and vanilla get mixed in with the smashed bananas. The dry ingredients get gently folded in with the wet. A white bowl of gluten free banana muffin batter.

I made this banana muffin recipe a couple of different ways during testing. My favorite was definitely with blueberries and walnuts. I love the sweet juiciness of the blueberries and the crunch of the walnuts. Walnuts have great nutrition too. A small bowl of granola and blueberries.

For even more crunch, I love a sprinkle of granola. I used Back To Nature Gluten-Free Honey Nut Granola. My family loves this granola on smoothie bowls and with almond milk or coconut yogurt. Bag of back to nature honey nut gluten free granola

This granola is made with honey that is sustainably sourced around the world and certified by GloryBee®. Their partnership supports their SAVE the BEE® initiative which supports the research, awareness and education needed to protect honeybees and promote healthy honeybee colonies! It’s nice to know these tasty products are non-GMO, inspired by nature, and made with real ingredients we can actually pronounce.

Banana oat flour muffins are so delicious that you would never guess they are made with such wholesome ingredients. They not only taste great, but make me feel so much better than any store bought muffin that’s filled with refined sugar, white flour, and loads of oil.

I like these muffins best slightly warm from the oven. Enjoy!
