Gluten free steel-cut oat banana breakfast muffins

Gluten free steel-cut oat banana breakfast muffins are simple to bake, healthy and gluten free, naturally sweet and easily adaptable!

IMG 0352I whipped up these absolutely delicious and healthy bakery-style muffins that will be sure to impress your taste buds while making you feel satisfied at the same time. The secret ingredient is steel cut oats; soaked overnight in almond milk (or water) which helps give this already high fiber treat an extra dose of filling nutrients like protein, calcium, magnesium & iron so after one serving our bodies can immediately start reaping all their benefits.

This muffin is naturally sugar-free, sweetened with honey and extra ripe bananas. They come together thanks to the pre-soaked steel cut oats making them moist and filling. This has been a favorite in my household! It wasn't long at all before they were gone, so I already have another batch in the oven as I create this blog post. We also love variations of this recipe like my Blueberry steel cut oat muffins, Peach apricot steel cut oat breakfast muffins or my Maple Pumpkin steel cut oat breakfast muffins.

You can add in berries or seasonal stone fruit if you desire. Keeping in mind they may need to bake a few minutes longer, as the fruit will add moisture to the batter. You can also add in anything else your heart desires, on this particular day - we added some chocolate chips to ours.

Tips for preparing to bake these gluten free steel-cut oat banana breakfast muffins:

Soak your steel cut oats overnight in water or milk. This will create a super thick batter, allowing your muffins to rise into bakery-style muffins. No dry or flat muffins here! This adds such a good, hearty texture. This step is necessary, as you want the oats to absorb the liquid. I've tried to simply skip this step and heat the oats before, but it results in a less than desirable texture in the muffin.

I hope you enjoy this high fiber treat with an extra dose of nutrients like protein, calcium, magnesium and iron. Send your family off to work or school with a breakfast that our bodies and tastebuds enjoy! 

Now let's get to baking!
