Preheat oven to 350 degrees F. Coat two 9-by-5-inch loaf pans with cooking spray.Advertisement
Stir all-purpose flour, whole-wheat flour, baking powder, baking soda and salt in a large bowl. Whisk eggs, egg whites, brown sugar, pumpkin and oil in another large bowl. Add the pumpkin mixture to the dry ingredients and mix until just combined. Scrape the batter into the prepared pans and smooth the tops.
Bake the loaves until the tops are golden brown and a cake tester inserted in the center comes out clean, 50 to 60 minutes. Cool in the pans for 10 minutes. Turn the loaves out onto a wire rack to cool completely.
Tips: White whole-wheat flour, made from a special variety of white wheat, is light in color and flavor but has the same nutritional properties as regular whole-wheat flour. It is available at large supermarkets and natural-foods stores and online at bobsredmill.com or kingarthurflour.com. Store it in the freezer.
