When I use my blender to make these things, I can add lots of stuff. Add apples with skins, zucchini, nuts, almost any fruit. I put all wet ingredients in the blender, holding back a little of the milk or whatever liquid I am using. Stir together all the dry ingredients in a large bowl. Pour the wet stuff from the blender into the dry stuff. Pour that reserved liquid into the blender to "wash" it. Now add that to the big bowl, mix it up and pour into pans.
