newton's law of cooling |
To put it simple newton's law of cooling states that objects cool/heat
faster when the temperature difference with their surroundings is
greater....so I assume that cooled/frozen chocolate would melt quicker
than chocolate at room temperature?

Newton's Law of Cooling
http://scienceworld.wolfram.com/physics/NewtonsLawofCooling.html
"For a body cooling in a draft (i.e., by forced convection), the rate
of heat loss is proportional to the difference in temperatures between
the body and its surroundings."

No, because they're not starting at the same point.
If you have a dragster going 250 mph and a VW going 30 mph and they
are both headed for the same parking spot, but the dragster is
starting from further away, can you tell from this information which
one is going to make it to the parking spot first?
