healthy banana muffins

i found the recipe here and then tweaked it a bit.  these are super moist and super tasty.  i didn't add the chocolate chips or pecans, but i'm open to adding them a different time for a treat.

1 1/2 cup all-purpose flour

1/4 C whole wheat flour
1/4 cup light brown sugar
1 teaspoon baking powder
1 teaspoon baking soda
1/2 teaspoon salt
2 tablespoons ground flax seed
1 egg
1/4 C oil
3/4 C applesauce
1 teaspoon vanilla extract
3 ripe bananas, mashed
3/4 cup chocolate chips (I use at least 60% cacao)
1/2 cup pecans, chopped

bake @ 350 for 20 minutes.
