1/3 cup whole flaxseeds (see Ingredient note)
1 cup whole-wheat flour
3/4 cup plus 2 tablespoons all-purpose flour
1 1/2 teaspoons baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
1 teaspoon ground cinnamon
2 large eggs
1/2 cup pure maple syrup
1 cup buttermilk (see Tip)
1/4 cup canola oil
2 teaspoons freshly grated orange zest
1 tablespoon orange juice
1 teaspoon vanilla extract
1 1/2 cups fresh blueberries
1 tablespoon granulated sugar

Ingredient Note: Flaxseeds, valued as a source of omega-3 fatty acids and fiber, can be found in the natural-foods section of large supermarkets and health-food stores. You must grind the seeds for your body to absorb the benefits.

Tip: You can use buttermilk powder in place of fresh buttermilk. Or make "sour milk": mix 1 tablespoon lemon juice or vinegar to 1 cup milk.
