Oh dear! You're right that cocoa powder can certainly be toxic to dogs; coffee can as well, since they don't tolerate caffeine very well. But the good news is, I would not expect a single prepackaged coffee drink like this to contain enough of either one to cause any serious toxicity issues in a large-breed dog. It's possible that he may have some mild stomach upset if he isn't used to eating things like this, but otherwise I would not expect to see any serious problems. To be safe, it would be best to monitor him for the next 12 hours for any signs of toxicity - which would include repeated episodes of vomiting or diarrhea, restlessness or hyperactivity, muscle tremors, or even seizures. If you see anything that concerns you, you can always take him to the vet to be checked.
