Mix together the flour, sugar, powder, soda, and salt.
In a separate bowl mix together the butter, bananas, eggs, and milk.
Pour into a greased bread pan. Bake at 350F for about 50 minutes or until a toothpick comes out clean.
Make sure you let it cool in the pan a little while before you take it out otherwise parts of the sides or bottom might come off because they are too hot.
