Melt in Your Mouth Banana Bread: The Tenderest, Most Buttery Loaf You’ll Ever Bake

Extra fat from butter AND oil – Butter for flavor, oil for tenderness that lasts for days

Buttermilk or yogurt – The acid tenderizes gluten for an impossibly soft crumb

Brown sugar – More moisture than white sugar alone

Very ripe bananas – The darker, the better (we’re talking black-peel territory)

Gentle mixing – Overmixing develops gluten, which makes bread tough
