Preheat oven to 375 degrees F and grease one 9x5 inch loaf pan or three smaller 3 1/10" L x 1 1/5" W x 1 2/5" H loaf pans.
In a large bowl, mix the brown sugar, maple syrup, yogurt, apple sauce, oil, egg. Add the rolled oats and let it sit for ten minutes.
In a separate bowl, combine the all-purpose flour, whole wheat flour, baking powder, baking soda, cinnamon and salt.
After the rolled oats have sat in the wet mixture for at least ten minutes, mix the wet and dry ingredients until just combined. Gently fold in the apples and pecans, being careful not to over-mix.
Slowly spoon mixture into your prepared loaf pans and sprinkle with rolled oats.
Bake in preheated oven for 40 minutes or until toothpick inserted into the center comes out clean.
