Peanut Butter Banana My Bad Bread

I was going to complain about this recipe I just tried to make for Peanut Butter Banana Bread. My result was a lump of glop with a crust around the edges. Could have sworn I followed every step, but I checked the recipe one last time to see what I might have left out. Probably including 1 and 2/3 cups of flour would have made a difference.
