That really depends on which desert and what you consider "really cold". As an example: Antarctica (the coldest region on the earth) is considered a desert and no matter what you consider "really cold" Antarctica is probably colder than that during the winter!
For comparison...
Sahara Desert average winter temperature: 13 ºC (55 ºF)
Arctic Desert (North pole area) average winter temperature −40 °C (−40 °F)
Arabian Desert average winter temperature 41 °F (5 °C) - with frequent frosts
Gobi Desert average winter temperature ~ -13 °F (-25 °C) - but reaching -40°F/-40 °C at times
Kalahari Desert average winter temperature ~32 °F (0 °C)
Patagonian Desert average winter temperature 34 °F (3 °C)
Great Victoria Desert average winter temperature 41 °F (5 °C) - with frequent frosts
Great Basin Desert average winter temperature ~32 °F (0 °C)
Note that even within these deserts there are considerable variations, especially with altitude; higher altitudes are colder. Deserts also characteristically have wider temperature swings than more humid areas. Temperature swings of 95 °F (35 °C) in 24 hours are not uncommon in the Gobi Desert. The Saraha has seen daytime to nighttime temperature swing from 37.5 to -0.5 °C (100 to 31 °F).
While the Taklamakan Desert can get quite hot during the summer it can also get bitterly cold in the winter. It is classified as a cold winter desert.
