Heat oven to 350 and prep a loaf pan by spraying cooking spray on the inside.
Cream room temperature butter and sugar until fluffy.
Add eggs to butter and sugar mixture. Mix until eggs are completely combined and mixture is smooth.
Add milk and vanilla to mixture.
Add bananas. I use a stand mixer, so I just throw the bananas in. If you're hand mixing, I suggest mashing them before adding to the mixture. Mix until smooth.
Whisk together flour, baking soda, and salt. Slowly add dry ingredients to mixture.
Add cinnamon to taste. I love lots and lots of cinnamon.
Pour batter into prepared loaf pan.
Bake for 55-65 minutes. Bake until the top of the loaf is golden brown and a toothpick inserted into the middle comes out clean.
Let loaf cool in the pan for 15 minutes.
Remove loaf from pan and allow to cool. Enjoy!
