1 1/4 cups all-purpose flour
1/2 cup whole wheat flour
3/4 cup ground flaxseed
3/4 cup packed brown sugar
1 teaspoon baking powder
1 teaspoon baking soda
1/4 teaspoon salt
1/2 cup 1% low-fat milk
1/2 cup orange juice
1 tablespoon butter, melted
1 teaspoon vanilla extract
2 large eggs, lightly beaten
2 cups finely chopped Granny Smith apple (about 1 large apple)
1/2 cup golden raisins (optional)
cooking spray

Preheat oven to 35o degrees. To prepare muffins, lightly spoon flours into dry measuring cups; level with a knife. Combine flours, flaxseed, and next 4 ingredients (through salt) in a medium bowl, stirring with a whisk. Make a well in center of mixture.

Combine milk, orange juice, melted butter, vanilla and eggs, stirring with whisk; add to flour mixture, stirring just until moist. Fold in apple and raisins. Spoon batter into 18 muffin cups coated with cooking spray.

To prepare streusel, combine walnuts, 2 tablespoons brown sugar and chilled butter in a small bowl, stirring fork until crumbly. Sprinkle streusel evenly over batter. Bake at 350 degrees for 20 minutes or until muffins spring back when touched lightly in center. (If you use convection oven bake at 325 degrees. If you use convection microwave back at 350 degrees.) Remove from pans immediately; place on a wire rack. Serve warm or at room temperature.
