This is a great banana nut bread recipe with banana flavor concentrate added.  It was a good recipe before added the flavor but the flavor makes it better.

Ingredients

2 cups all-purpose flour
1 teaspoon baking soda
3/4 teaspoon salt

1 3/4 cups ripe mashed banana
3/4 cup granulated sugar
1/3 cup plain yogurt (not low fat)
1/4 cup vegetable oil
3 large egg yolks
1/2 teaspoon vanilla extract
1 teaspoon banana flavor concentrate

1 cup pecan or walnut pieces

Directions

Preheat the oven to 350 degrees.

1. Mix the flour, baking soda, and salt together in a large bowl.
2. In another bowl, mix the mashed banana, sugar, yogurt, vegetable oil, egg yolks, vanilla, and banana flavor together.
3. Add the wet ingredients to the dry and stir just until the ingredients are mixed well.  Fold in the nuts.
4. Spoon the batter into a well-greased and floured 9 x 5 loaf pan.  Bake for 45 to 55 minutes at 350 degrees or until it tests done with toothpick.
5. Let sit for five minutes in the pan on a rack and then remove the loaf from the pan and place on a rack to completely cool.   For the best flavor, wrap tightly in foil or plastic and store overnight in the refrigerator.
