Grandma's Banana Bread (Updated)

I grew up on this banana bread.  My mom made it whenever there were overripe bananas to be had but the original recipe came from my grandma.  I've always loved this banana bread both because it's delicious but also because it reminds me of childhood and my mom and grandma.  Recently, however, I tried to update it a bit from it's original form to cut back on the amount of butter and sugar.  As it is now written, the recipe has half the amount of butter and a quarter less sugar than the original. I think it turned out really well without sacrificing the original flavor.  This is how I make it all the time now.  Delicious!

Banana Bread
1 loaf

1/4 c. butter
1/4 c. applesauce (or 2 T. non-fat plain greek yogurt)
3/4 c. sugar
2 eggs (or 1/2 c. egg substitute)
1 t. soda dissolved in 1 T. sour milk
3 ripe bananas
2 c. flour
1/2 t. baking powder
pinch of salt

Cream butter and applesauce and then add in sugar.  Beat in eggs and the soda dissolved in sour milk.  Finely mash the bananas and add to the mixture.  Add remaining dry ingredients and combine.  Pour into a bread loaf pan sprayed with non-stick cooking spray.  Bake at 350 degrees for 1 hour.
