Preheat the oven to 350°F (175°C).

In a mixing bowl, mash the bananas until smooth.

Add melted butter to the mashed bananas and mix well.

Stir in the sugar, beaten eggs, and vanilla extract.

Sprinkle the baking soda and salt over the mixture and mix in.

Add the flour and dates, and mix until just incorporated.

Pour the batter into a greased loaf pan.

Bake for 60 minutes or until a toothpick inserted into the center comes out clean.

Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
