It’s hard to beat the convenience of a grab-and-go treat, and these banana olive oil muffins check all the boxes: They can be a quick breakfast, a midday snack, or a simple dessert. They’re accidentally vegan, relying solely on overripe bananas and bright, citrusy extra-virgin olive oil for a moist, tender crumb. Warm spices like cinnamon, nutmeg and vanilla are added to enhance the sweet banana flavor, alongside molasses-packed dark brown sugar. A sprinkle of turbinado sugar and flaky salt sprinkled over the muffins before baking ensures an irresistible sweet-and-salty crunch in each bite. For the perfect level of sweetness, using very ripe, soft and spotty bananas is a must, as they come with a significantly higher sugar content.

Preparation

  1. Step 1

    Heat the oven to 425 degrees. 

  2. Step 2

    Lightly brush a standard 12-muffin pan with olive oil and line with muffin cups. 

  3. Step 3

    In a large bowl, combine the mashed bananas, olive oil, dark brown sugar, vanilla extract, cinnamon, nutmeg and 1 teaspoon flaky salt. Stir until combined. 

  4. Step 4

    Add the flour, sprinkle with the baking soda and baking powder and lightly stir just the dry ingredients to evenly distribute the leavening agents through the flour. Stir the wet ingredients and flour mixture together until there are no visible dry flour spots. 

  5. Step 5

    Using a ⅓-cup measure or ice cream scoop, divide the batter among the 12  muffin cups. Sprinkle the turbinado sugar on top of the muffins. Add the remaining 1 teaspoon of flaky salt to your palm and sprinkle it over the muffins. 

  6. Step 6

    Place in the oven and immediately reduce the heat to 350 degrees. Bake for 20 minutes, until a knife comes out clean when inserted in the center of a muffin. Cool the muffins for a few minutes before serving. Muffins will keep, covered at room temperature, up to 3 days.

half the amount of sugar is definitely sufficient here. used half almond flour to make them more substantial.

Something is definitely off with this recipe - I had a whole batch of these sitting in the kitchen, and every time I would walk in there, more and more pieces would be missing. One even looked like a bite had been taken out of it! My fiancee is just as perplexed as I am. Maybe it's the way the ingredients are interacting.

@Cassie I made these using Bob’s Red Mill 1-for1 gluten free flour and it was successful. I would expect same from KA. Not sure if it had a significant impact, but I did accidentally tweak the recipe (grabbed the wrong measuring spoon, so I added 2/3 tsp each of baking powder and baking soda instead of the 1/2tsp specified in the recipe). I also added about 1/2 tsp psyllium husk out of habit from my usual GF vegan bakes. I also made a point of mashing the bananas extra smooth (almost a purée) to try to mitigate the gumminess tendency of GF bakes. Was very happy with the muffins and will bake again.

I have made these muffins several times and discovered the first time, when I heated the oven to 450 and was supposed to turn the heat down but didn’t, that 20 minutes at 425 made wonderful muffins that weren’t at all charred but sightly browned on top and full of flavor. We love these muffins. I also use half almond flour and half whole wheat. They are delicious.

Seems like 20 mins wasn’t nearly long enough for us, either! Got confused between the “20 mins” as written in the recipe instructions and the “35 mins” referenced in the time summary at the top of the recipe. Accidentally cooked them for 35 mins, and they are absolutely fabulous. Best banana muffins I’ve ever had.

Made these and swapped half the flour for almond flour. I also used whole wheat flour for the other half. They are delicious but also a bit wet and oily. Perhaps next time I would use regular vegetable oil instead of olive oil which I can’t taste in the final product (unlike, say, a lemon olive oil cake) to see if it make it less greasy. They are also super sweet. Overall ok.
