Moistest Banana Bread Ever

This has become my go to banana bread recipe.  I love it.  Seriously, the moistest banana bread ever.

2 cups sugar
1 cup softened butter
5 eggs
2 cups flour
6 T buttermilk (or regular milk will work too)
2 t. baking soda
1 1/2 cups ripe bananas (4-5 bananas)
1 t. vanilla

Optional:  I usually throw in some chocolate chips too.  Maybe 3/4 cup or so.

Mix all the ingredients together until just blended.  Cover the mixture and place it in the refrigerator for an hour.  Pour mixture into a greased bundt pan.  Bake for 40-55 minutes at 350, until a toothpick comes out clean when checking near center.  Let cool and then invert onto a plate.
