chocolate cake made with mayo

I am looking for a recipe for a choc. cake using mayo.  For a 9X 13 pan.  My mother made one back in the 60's.  Thanks

We always called this Miracle Whip cake. 

Very moist and tender.  It doesn't really need any frosting.

Is this recipe for a 9X13 pan?

Yes, sorry.  I guess I didn't realize the recipe didn't specify.

I always grease and flour the pan before adding the batter also.

Not sure if it's really necessary though.
