Whole-wheat flour and flaxseeds give these maple syrup-sweetened blueberry muffins a delicious, nutty flavor. Compared to a traditional version of the recipe, they have four times the dietary fiber and substitute healthful monounsaturated fat (canola oil) for saturated fat (butter).
- Preheat oven to 400°F. Coat 12 muffin cups with cooking spray.
- Grind flaxseeds in a spice mill (such as a clean coffee grinder) or dry blender. Transfer to a large bowl. Add whole-wheat flour, all-purpose flour, baking powder, cinnamon, baking soda and salt; whisk to blend. Whisk eggs and maple syrup in a medium bowl until smooth. Add buttermilk, oil, orange zest, orange juice and vanilla; whisk until blended.
- Make a well in the dry ingredients and stir in the wet ingredients with a rubber spatula just until moistened. Fold in blueberries. Scoop the batter into the prepared muffin cups. Sprinkle the tops with sugar.
- Bake the muffins until the tops are golden brown and spring back when touched lightly, 15 to 25 minutes. Let cool in the pan for 5 minutes. Loosen edges and turn muffins out onto a wire rack to cool slightly.
