Peel the ripe bananas and mash them up in a large mixing bowl.

Next, you'll need to mix the wet ingredients. To the bowl of bananas, add the olive oil, brown sugar, vanilla, salt, and eggs. Stir everything until it’s nicely mixed.

In another bowl, whisk together the whole wheat flour, cinnamon, baking powder, and baking soda.

Slowly mix the dry ingredients into the wet ingredients. Stir it all together, but don’t overdo it - just mix until it’s combined.

Preheat your oven to 350 degrees F (that’s about 175 degrees C). Then, get your muffin pan or loaf pan ready. You can grease it up with butter or oil, or use paper cups for muffins.

Pour your batter into the pan or scoop it into the muffin cups. If you’re using it, now’s the time to sprinkle that turbinado sugar on top.

Place the tray into the oven. Muffins will need about 25 to 30 minutes to cook all the way through, and a loaf might need a bit longer. You’ll know it’s done when the top is nicely browned, and it feels firm if you give it a gentle poke. You can also insert a toothpick into the center to see if it comes out clean. 

Remove from the oven and cool at room temperature before serving.
