And just such a cake has been found in Cape Adare, East Antarctica, by the Antarctic Heritage Trust.
The conservators believe the cake was brought by British explorer Robert Falcon Scott during the 1910-1913 Terra Nova expedition.
A team from the Canterbury Museum in Christchurch has recently finished a 14-month project conserving nearly 1,500 artifacts from Cape Adare.
According to experts, the cupcake was part of the provisions of the Northern party of the expedition, "Terra Nova", the members of which lived at Cape Adair.
"It's an ideal high-energy food for Antarctic conditions, and is still a favourite item on modern trips to the ice". But the most surprising is definitely the century-old fruit cake.
A fruitcake was found in the coldest and driest place on Earth, Antarctica.
Lizzie Meeks, the trust's artefacts manager, said the cake was found among a stock of food supplies abandoned by... "The cake itself looked and smelled (almost) edible" and was in "excellent condition", the researchers claimed.
The delicacy, made by British cake makers Huntley and Palmers, was still wrapped in paper and encased in the remains of a tin-plated iron alloy tin, the researchers at the Antarctic Heritage Trust in Christchurch said in a statement on Thursday.
Scott's famous Antarctic expedition was both scientific and powered by a desire to be the first person to reach the South Pole. Conservators are now planning to conserve the huts that were built in 1899 by Norwegian Carsten Borchgrevink and used by Captain Scott in 1911.
"Great God! this is an bad place and terrible enough for us to have laboured to it without reward of priority", Scott wrote in his diary.
