Preheat oven to 350.

In a large mixing bowl, mix together the butter and sugar til it is a crumbly semi creamy texture.

Beat in the egg then add the mashed bananas.

Mix in the flour, baking soda, and salt.

Make sure all the other ingredients are mixed together well, then add the splash of milk. Not too much, but just enough so the batter isn't too thick.

Then mixed in any desired add on ingredients, like chocolate chips or walnuts.

Grease a 8x4 in loaf pan and pour batter inside. Bake in heated oven for approximately 1 hour.
