Olive oil is a type of vegetable oil - it has aricher taste and I think it's actually better for you than regular veggie oil (more monounsaturated fats!). I have used olive oil in recipes calling for veggie oil without too much noticeable difference. I would use the same amount of olive oil as veggie oil. Good luck!
you can, however extra virgin olive oil does have a specific taste to it. The difference between the two is olive oil comes from olives and vegetable oil is made from soybeans. You would use the same amount. Chocolate is a very powerful flavor and may over power the flavor of the olive oil. Other than that it is okay. Happy baking.
