Zucchini Bread

Preheat oven to 350 degrees F. Coat two 9-by-5-inch loaf pans cooking spray. Spread oats and pecans on separate parts of a baking sheet and bake until lightly toasted, 5 to 10 minutes; let cool. Chop the pecans.

Stir together all but 2 tablespoons of the toasted oats, the pecans, white and whole-wheat flours, baking powder, cinnamon, nutmeg, cloves and salt in a mixing bowl. Whisk together brown sugar, eggs, egg whites, apple butter and oil in another bowl; stir in zucchini. Stir the wet ingredients into the dry ingredients just until well combined.

Divide the batter between the prepared loaf pans, smoothing the tops. Sprinkle 1 tablespoon of the reserved oats on top of each loaf. Bake until the tops feel firm when lightly pressed and a skewer inserted in the center comes out clean, 45 to 55 minutes.

Let the loaves cool in the pans for 5 minutes; turn them out onto a wire rack to cool completely.
