Preheat the oven to 350F (177C).

Prepare a loaf pan, greased and lined with parchment paper.

Place the butter and sugar into a bowl and cream together using electric beaters or a stand mixer with the paddle attachment.

Add the eggs one at a time and mix, scraping down the sides of the bowl between each addition. Add the vanilla and mix.

Add the mashed banana and mix gently.

In a separate bowl, sift together the flour, salt and baking soda.

Add the dry ingredients into the wet mixture and mix until just combined, taking care not to over-mix the batter.

Pour the batter into the prepared loaf pan and bake for 60 minutes or until a toothpick comes out clean.

Remove the loaf from the pan and cool on a wire rack.
