Preheat oven at 350°F/180°C
Butter and flour 2 standard loaf pans. You can use baking spray or any baking pan release.
Peel, mash and messure the bananas
Sift all the dry ingredients and set aside.
Place the butter and sugar on the bowl of your stand mixer. Let it mix until light and fluffy. It will take around two to three minutes. With a rubber spatula, scrape the sides and bottom of the bowl to ensure the ingredients are incorporated.
With the mixer on low to medium speed, start adding the banana puree, mixing until well combined. Don't over mix.
Add the eggs one by one, mixing after each addition.
Add the vanilla, and go ahead and scrape all sides again.
Turn your mixer down to low speed and start adding thr dry ingredients little by little. I use one of the measuring cups. This way I dont make a mess or get covered in flour. Continue to add the dry ingredients and mix until well combine. Make sure to not overmix. This step can even be done by hand.
