During the descent into DEN; I was aware of the fuel temperature and the fact that we were tankering a significant amount of fuel. I mentioned to the First Officer that we would not be loading much fuel to raise the fuel temp and would probably have CSFF [Cold Soaked Fuel Frost]; with probable de-ice requirements.  Fifteen minutes after arrival; I checked both wings and it appeared as if we had CSFF.  I planned on checking the condition of the wings prior to departure.  Due to a very early arrival and an already long (55 min) turn we had almost 1.5 hours in DEN.  I guess I had too much time on my hands; as I forgot to re-check the condition of the wings prior to departure. I realized my mistake after takeoff.  It is possible that I departed with cold soaked fuel frost on one or more wings; but I don't know.
[Report narrative contained no additional information.]
After landing with nearly full fuel tanks in just above freezing conditions the flight crew of a B737NG planned--but failed--to check the tops of the wings for cold soaked fuel frost prior to their subsequent takeoff.  A lengthy layover permitting intervening distractions may have been a contributing factor.
