You want COMPLETE mix only requiring added water. If you buy a pancake mix that requires eggs, then you will need to add eggs (follow directions for # of eggs per 2 cups of mix). Complete pancake mix includes several of the ingredients in a banana bread recipe...all purpose flour, baking powder, sugar, salt...all pre-measured and combined for you.  NOTE: I used Aunt Jemima Complete Pancake Mix Buttermilk.  I also tried Maple Grove Farms Complete Pancake Mix and both worked great.
