Chocolate Cake Again

I just baked a chocolate cake using canola oil instead of butter. I hope it turns out good. It is still in the oven baking. I prefer using oil as it is cleaner and the untensils are easier to clean. The downside is that butter gives better aroma. Normally I can smell the cake while it is baking however I cant smell anything right now (the cake is going to be done in another 10 mins).
