Instructions 

Prepare a pan and preheat the oven:

Prehend the oven to 175°C (350°F). For simple removal, grease and flour a 9-by-5-inch loaf pan or line it with parchment paper.

Combine the all-purpose flour, baking powder, baking soda, and salt in a basin by sifting. Discard this powdery mixture.

Compot the sugar and butter:

Using a hand mixer or stand mixer, blend the softened butter and granulated sugar in a separate large mixing basin until light and airy.

Incorporate vanilla and eggs:

Gradually incorporate the eggs, ensuring thorough blending following each addition. After that, incorporate the vanilla extract by stirring.

Integrate the moist and dry components:

Combine the blended bananas. Subsequently, incorporate the flour mixture and basic yogurt (or sour cream) in tripartite successions, with the flour portioning off last.

Combine just until incorporated. Avoid overmixing.
