I’ve been talking a lot about getting our dinner game to be a little stronger, and you know what? It made me realize that our breakfast game is a little pathetic too. There’s lots of scrambled eggs, toast, and cereal going on, and not much else.

But I’m a baker, for goodness sake! Why am I relying on boxed cereals and toast, when I could be making a weekly batch of muffins, scones, and quick breads instead? Especially when I can customize them to our liking, and they’re super portable when we’re heading out the door as we run to the Little Gym or swimming lessons.

Olive Oil Banana Muffins are the perfect way to start your day! Loaded with banana flavor and crunchy walnuts, they're the perfect portable breakfast!

I’ve also been experimenting a little more with other kinds of fats in our baked goods. Don’t get me wrong, I’m still a dessert blogger, and there’s no way I’m giving up butter. But it’s kind of fun to switch up your routine and try something new.

Thus was the case with these Olive Oil Banana Walnut Muffins. My friend Amber mentioned making them a time or two for her hubby, who has some cholesterol issues. His doctor told him olive oil is a better fat for him to ingest than butter, with his particular issues, so she started making these regularly, and couldn’t get over their buttery, but also extremely nutty flavor. The kind of flavor that pairs perfectly with toasted walnuts.

Olive Oil Banana Muffins Ingredients Picture

Now, I use walnuts, pecans, and almonds in a lot of my baking, and there’s a lot of research around walnuts and their healthy Omega-3 fatty acids. I’ll certainly let you do the research for yourself and talk to your doctor too – but I also just happen to love walnuts. And I choose to work with Fisher nuts because it is one of the only brands of recipe nuts entirely without preservatives. Nuts are perfect as they come off the tree, so I don’t see why we would ever need to mess with them.

Everyone’s got bananas hanging around longer than they expect to. It happens to us almost weekly. And I really, really dislike throwing away food. So I decided to do something about it, and whip up these Olive Oil Banana Walnut Muffins.

Olive Oil Banana Walnut Muffins are a light and sweet start to any day. Walnuts add a crunch that makes them a little more special!

Let me tell you something about olive oil in muffins. It turns downright browned butter-esque. If you’ve ever browned butter to make a baked good, you understand what I’m talking about. There’s a toasty quality that keeps you coming back again and again, for just one more bite. And olive oil does the same thing, without the extra work and dirty saucepan!

I won’t lie, I was a little worried about my muffins tasting like olives, but they definitely do not. They taste toasty, nutty, with the perfect amount of bite added from toasted walnuts.

Breakfast just got epic around here, and I hope it’s going to around your house too, because YUM!

For the Muffins

  • 1 ¾ cup white whole wheat flour see not below
  • 1 teaspoon baking soda
  • ½ teaspoon ground cinnamon
  • ½ teaspoon salt
  • cup olive oil
  • ½ cup granulated sugar
  • ¼ cup packed light brown sugar
  • 2 large eggs
  • 1 cup mashed ripe bananas
  • 1 teaspoon vanilla extract
  • ¼ cup hot water
  • 1 cup chopped Fisher Nuts walnuts or pecans

For the Crumb Topping:

  • cup packed light brown sugar
  • ¼ cup white whole wheat flour
  • ¼ cup oatmeal
  • ¼ cup chopped Fisher Nuts walnuts or pecans
  • 3 tablespoons olive oil


  • Preheat oven to 325°F. Line a standard muffin tin with paper liners.
  • In a medium bowl, whisk together the flour, baking soda, cinnamon and salt.
  • In the bowl of a stand mixer, or in a large with an electric mixer, combine olive oil and sugars until thoroughly combined.
  • Beat in eggs until incorporated and stir in bananas, vanilla and water.
  • Add dry ingredients to the wet ingredients and mix until just combined and gently stir in chopped nuts.
  • Use a large cookie scoop to evenly distribute the batter between the prepared muffin wells.

For the Crumb Topping:

  • Stir all ingredients together in a small bowl. Make sure the olive oil is thoroughly incorporated.
  • Sprinkle each muffin with the crumble topping, pressing it in gently.
  • Bake in preheated oven for 20-23 minutes, or until the muffins are golden brown and slightly firm to the touch.
  • Allow to cool for 5 minutes in the pan, then remove to a cooling rack and allow to cool completely.


  • If you would like to substitute the white whole wheat flour for all-purpose flour, simply add in the same amount, but eliminate the hot water. If you're batter seems a little dry, add the water into the batter one tablespoon at a time until it is moistened.

    I made these muffins today :) I followed the recipe but substituted all purpose white flour for the whole wheat flour. I did add 3 Tbls hot water as suggested in using white flour and they turned out perfect. I wondered if I should use either light or full bodied olive oil, but ended up using full bodied and there was no heavy olive oil taste. I did not add the additional crumb topping (will try next time) and muffins were super delicious just plain! They baked up nice and tall and were moist. Thanks for a great recipe :)

      So glad you enjoyed, Kay! Thanks so much for stopping by and sharing your feedback. Happy baking!

  2. Janet says:

    For the Crumb Topping, you have oatmeal listed in the ingredients – do you mean quick cooking oats or rolled (old fashioned) oats? Thank you!

    1. Jamie says:

      Hi, Janet! You can actually use either. The old fashioned oats will give you a heartier texture. I hope you enjoy them!

  3. Kathie says:

    Hi Jamie
    I love these, they turned out great! Do you think this could be made in a loaf pan instead of muffins?

    1. Jamie says:

      I’m so glad you liked them, Kathie! I think you could definitely make these into a loaf/quick bread. You’ll probably have to bake it close to an hour and tent foil over the top to prevent the streusel from browning too quickly. Let me know how it goes!

  4. Anina says:

    Hi Jamie! 

    It has been a long while since I’ve visited your blog, and today I made these muffins for my very fussy 6 year old. You have a sure hit here, girl! 

    My new go to recipe for sure! I normally  use my banana bread recipe for my muffins, and mine asks for butter (didn’t have any) and wonderful google directed me here!


    1. Jamie says:

      I’m so glad to hear that, Anina! Best wishes!

    One can’t ever give up butter…never! 
    But I would eat the whole pan of these muffins…no issue!

    1. Jamie says:

      You and me both, Girl! Thanks so much for stopping by!

  6. Gina @ Running to the Kitchen says:

    I’ve done an olive oil zucchini lemon cake before that is the moistest most delicious thing ever so I can just imagine how these muffins are. Plus, that crumb topping is on point!

    1. Jamie says:

      I’m pretty convinced that crumb toppings make everything amazing. Thanks for stopping by, Gina!
