- Preheat oven to 350°.
- Combine first four ingredients in a large bowl; beat with a mixer at medium speed. Beat in sugar.
- Combine flour and next four ingredients (flaxseed through cinnamon). Add flour mixture to banana mixture; mix just until blended.
- Spoon batter into a 12-count muffin tin filled with nonstick paper liners. Sprinkle each muffin with 1 teaspoon walnuts and bake at 350° for 20-25 minutes or until a wooden pick inserted in center comes out clean.
- Remove from oven; cool 5 minutes in pan. Remove muffins to wire rack and cool completely.
Bake time may take 20-25 minutes.
