I've tried several recipes for using up past-their-prime bananas, and this is my favorite. I altered a recipe I found online. It has buttermilk in it which I have come to believe makes any baked goods ten times better.
Sorry I don't have any artsy pictures to share with you...
2 eggs
1/3 cup buttermilk
2 mashed overripe bananas
1/2 cup butter
1 1/2 cups brown sugar
1 tsp vanilla
1 3/4 cup flour
1 tsp baking soda
1/2 tsp salt
1 tsp cinnamon
Preheat oven to 375 and grease your bread pan. Cream butter and sugar. Add eggs, bananas, vanilla and buttermilk and mix well. In a separate bowl mix dry ingredients and then add to wet and mix until well incorporated. (I am very lazy and reluctant to dirty another bowl so I usually just dump everything into my stand mixer together.) Bake until the top doesn't jiggle when you give the pan a good shake. Sorry I don't have an exact time frame for you...I also think the addition of nuts or chocolate chips or even a cream cheese icing would be delicious if you want to get fancy!
