September 3, 2019 / Updated on September 9, 2019 By Leanne 39 Comments

Healthy Banana Nut Muffins are soft and hearty, with bananas and walnuts, and wholesome ingredients including steel-cut oats and whole wheat flour. They come together in just one bowl with vegan, gluten-free and nut-free options included.

It’s back-to-school week in many places so I thought it was a good time to share a few of my go-to healthy snacks. First up are these banana nut muffins made with overnight oats. They’re wholesome and filling, and perfect for an afternoon snack or quick breakfast as you’re heading out the door.

And I’ve included a nut-free version in the notes so they can also be packed in school lunches.

Ingredients for making these easy banana nut muffins:

Steel-cut oats
Nut milk
Overripe bananas (mashed)
Egg
Extra virgin olive oil
Honey
Whole wheat flour
Coconut sugar
Baking soda, cinnamon and salt
Walnuts

How do you make these banana nut muffins with overnight oats?

This is a one-bowl situation so these healthy banana nut muffins come together easily.

Start by adding your oats and nut milk to a large bowl and let them soak until the nut milk is fully absorbed (I usually do this overnight).

Once the oats are soaked, whisk in your mashed bananas, egg, oil and honey. Next, add the flour, sugar, baking soda, cinnamon and salt. Stir until just combined. Fold in the walnuts.

Divide the batter evenly into a 12-cup muffin pan and bake at 425F for 16-18 minutes.

Let cool and store in a container. Or slather on some butter or honey and enjoy warm!

How can I make these banana nut muffins nut-free?

To make these muffins nut-free, just substitute dairy milk for the nut milk, and replace the walnuts with pumpkin seeds, raisins or chocolate chips. The nutty texture of the steel-cut oats will still give these banana muffins a nutty vibe.

How can I make these banana nut muffins gluten-free?

If you’d like to make these muffins gluten-free, you can substitute the whole wheat flour for gluten-free flour. You’ll also want to make sure the oats you’re using are certified gluten-free. The muffin texture will be a little different, and the tops will bake up a little crackly instead of dome-shaped. But they will still turn out soft and hearty.

How can I make these banana nut muffins vegan?

For a vegan version of these muffins, replace the honey with maple syrup and use a flax egg instead of an egg. I always refer to this How to Make a Flax Egg tutorial.

Some more tips and substitutions for making these healthy banana nut muffins:

If you’re pressed for time, or don’t have steel-cut oats, you can use quick cooking rolled oats and soak them for 30-60 minutes. They won’t create the same nutty texture, but they still work well in this recipe.

I usually make muffins with whole wheat flour, but if you only have all-purpose white, it will work in this recipe too.

If you don’t have coconut sugar, you can substitute brown sugar.

I always find that dark coloured pans brown the muffins faster, especially on the bottom. So if you’re using a dark pan, just keep an eye on the muffins as they near the end of their bake time.
