GASP!! A cake mix, Jen?? Just kiddin with ya. One of my favs is the Darn Good Choc Cake from the Cake Mix Doctor. Pair it with a good ganache and I am in heaven.
Do you use all of the butter in the WCCC BC? I made it the first time yesterday to pair with the Silver Palate Carrot Cake that Jeanne posted. I will post a review on the carrot cake post later. Anyway, on its own I tasted the butter a little too much for my liking but less when I tried it with the cake. But I think I could still stand to reduce the butter a little. And it turned out a little thin for me. But it could have been a combination of me rushing and not letting the WC cool enough and my butter being too soft.
My fav RV recipe is from Marcy Goldman. I hesitated posting this since you have to pay to get the recipe from her website. But let me know if you are interested and I can ask her if I can post it. It has quite a bit of cocoa and you can taste it but not so much that it tastes like a chocolate cake. I think the debate on whether or not RV should taste like vanilla or choc (or whether it should have cream cheese or old-fashioned frosting) will go on forever. I don’t know which is correct but I just know what I like. This one also has sour cream and butter in it and no buttermilk or vinegar.
