A Labrador retriever can eat a tractor tire without any consequences... They are truly a miracle of digestion!

That said, the effects won't start for a quite a while, like 6 or 8 hours. So call your vet to be safe. if you can't get the vet, induce vomiting (hydrogen peroxide will make them vomit). About a teaspoon per ten pounds of weight of 3% solution. Use a turkey baster. If you haven't done this before, this is my preferred method. Have the dog sit backside toward a wall. Straddle the dog, facing same direction as the dog. Use left hand to point the head up toward you, slide the dog's lips over their teeth with the left hand. They'll open the mouth right up. In goes the turkey baster, give it a blast and clamp the mouth shut, rub their throat. They'll swallow. They'll be a pit pissed, but they'll get over it. Usually puke a few minutes later.

I really doubt that there is enough chocolate in that cake to cause an 85 pound dog any problems, especially a Labrador retriever which I swear to God can eat anything. But if you are really concerned... proceed with the above.
