Peanut Butter Banana Cake

I've had this well-worm recipe for as long as I've been married. I often make it for potluck functions. The ladies love it, but the heavy texture is a real favorite with men.—Lee Deneau, Lansing, Michigan

    My family & I didn't really like the combination of the peanut butter & banana. I wound up throwing it out.
