Add eggs one at a time while the mixer is going
Then add vegetable oil slowly while mixing.
In a separate bowl, mix dry ingredients including whole wheat flour, salt, baking soda, and cinnamon
Blend or Whisk dry ingredients together until homogenous
Combine dry ingredients 1 cup at a time while blending, adding when fully incorporated

In a separate bowl, mash bananas with a fork and add walnut pieces
