Buttermilk Devils Chocolate cake

Okay so I don't have pictures of this one but I've made it several times and it's definitely a keeper so I'll take a pic next time I use it. It's so easy and make a plain devils chocolate mix so much better. I also love these because they come out shaped perfectly with raised, round tops.

1 box Devils chocolate mix
1 1/3 C buttermilk
1/2 c veg oil
2 T cocoa powder (if you want it REALLY rich, use dutch process cocoa, they have it at most grocery stores)
3 eggs
1 t vanilla (I did almond extract once)

follow same directions as all my other cupcakes, or you can use it for making cakes too.
