1 1/2 cups whole wheat flour
3/4 cup ground flaxseed
2 tsp baking powder
1 tsp baking soda
1 tsp cinnamon
1/2 tsp salt
3 very ripe, medium bananas, mashed
6 tbsp brown sugar
3/4 tbsp lemon juice plus enough skim milk to make 3/4 cup (or use 3/4 cup buttermilk)
4 egg whites
1 tsp vanilla
3/4 cup chopped walnuts
Preheat oven to 180 (350) degrees. Spray loaf pan with non-stick spray. Measure 1 tbsp lemon juice (freshly squeezed is best) into a measuring cup and pour in skim milk for a total of one cup. Do not stir. Allow to sit for 5 minutes. Alternatively, you can simply use 1 cup of buttermilk if you have this ingredient on hand.
In a large bowl, blend flour, flaxseed, baking powder, baking soda, cinnamon and salt and set aside.
Beat egg whites and sugar. Add bananas and vanilla and beat lightly.
Pour wet ingredients into dry ingredients and combine until well mixed. Add walnuts and stir until combined.
Pour mixture into loaf pan and bake 40 to 50 minutes.
