We have just started making this healthy banana bread recipe from Whole Foods - a great source for kid-friendly healthy recipes. My daughter loves it and it comes out moist and yummy ... and very tasty. Has flax seed, yogurt, etc.
Oh, we also use whole wheat flour for the whole thing ... no all-purpose at all and have had no issues.

Light-n-Luscious Banana Bread
1 1/2 cups unbleached all-purpose flour
1/2 cup whole wheat flour
1 teaspoon baking soda
2 tablespoons ground flax meal
1 tablespoon ground cinnamon
1/2 teaspoon salt
1/2 stick (1/4 cup) unsalted butter, softened
1/2 cup granulated sugar
2 eggs
1/3 cup fat free or low fat plain yogurt
3 very ripe bananas, smashed (about 1 1/2 cups)
2 teaspoons vanilla extract
1 tablespoon turbinado sugar
Method
Preheat oven to 350°F. Spray an 8-inch x 4-inch metal loaf pan with cooking spray; set aside.
Whisk together both flours, baking soda, flax meal, 2 teaspoons of the ground cinnamon and salt; set aside.
Cream together butter with sugar using a mixer. Add eggs, one at a time, beating well after each addition. Mix in yogurt, bananas and vanilla. Fold in flour mixture and mix until just incorporated. Spoon batter into loaf pan.
Stir together turbinado sugar and remaining 1 teaspoon cinnamon. Sprinkle over the top of the banana bread. Bake 55 to 60 minutes or until a knife inserted in the center of the loaf comes out clean. Allow to cool slightly, then remove from baking pan.
Chef’s Tip: If using a glass baking pan, decrease cooking time by 5 to 10 minutes.
