Sock It to Me Cake

I remembered my mom making this when I was little. I went searching for a recipe and thought this sounded like the one closest to what she made. The original recipe didn't call for the vanilla, that was my addition. I like to add vanilla if I'm using a box mix. When I took her some and asked if it was as good as she remembered, she said it was better.
