Recipe like Entenmann's Butterscotch Cake?

I used to LOVE Entenmann's butterscotch cake. I think it was just a yellow cake with butterscotch frosting but i'm not totally sure. Now they don't carry it anymore and I have been craving it for years. Does anyone else remember this cake? Is there anywhere to still get it or does anyone have a copycat recipe that tastes the same? Thanks!
