Preheat oven to 400°F (200C/180C Fan) and line an 8" springform cake pan with parchment paper. This should be a large piece of parchment paper, crumpled into the pan and overhanging the lip by a couple of inches (see images in post).
In a large mixing bowl, beat together the cream cheese and sugar. Add the eggs one at a time, beating well after each addition.
Add the flour and whisk into the mix, followed by the eggnog.
Pour into the prepared cake tin and bake in the centre of the oven for about 45 minutes, watching for it to be risen, jiggly and well browned on top.
Remove from the oven and allow to cool at room temperature for an hour before placing in the refrigerator for at least four hours (or overnight).
When ready to serve, carefully remove from the springform pan and transfer to a serving plate. You can leave the parchment paper around the cake for presentation. Slice and dust with freshly grated nutmeg.
