A tender, ultra-moist banana bread made with very ripe bananas, a touch of sour cream, and a balance of butter and oil for richness. Simple, forgiving, and perfect for breakfast or snack time.
Preheat oven to 350°F (175°C). Grease a 9x5-inch loaf pan and line it with parchment paper, leaving an overhang on the long sides for easy removal.
In a large bowl, mash the ripe bananas until mostly smooth. Stir in melted butter and oil. Add sugar and whisk lightly. Beat in eggs one at a time, then fold in sour cream (or Greek yogurt) and vanilla.
In a separate bowl, whisk together flour, baking soda, baking powder, salt, and cinnamon.
Add the dry ingredients to the wet mixture and stir gently until just combined. Fold in any optional mix-ins like chocolate chips or nuts. Avoid overmixing to keep the crumb tender.
Pour batter into the prepared pan and smooth the top. Bake for 55–65 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs. Tent with foil if top browns too quickly.
Cool in the pan for 10–15 minutes, then lift out using the parchment and transfer to a wire rack to cool completely. Slice and serve at room temperature or slightly warmed.
Notes
Use very ripe, spotty bananas for maximum flavor and moisture.
Substitute plain Greek yogurt or buttermilk for sour cream if needed.
To make muffins, bake at 350°F (175°C) for 18–22 minutes.
Store wrapped at room temperature for 2 days, refrigerate up to 1 week, or freeze sliced for up to 3 months.
