Grate the peeled carrots, drain as much liquid out of them as possible, and then place in a towel and wring out any remaining liquid. Add to mixing bowl along with the ginger, sweetener, spices & lemon zest, mix well.
Separate the egg yolks and add to mix, beat the whites until stiff then fold into the mixture.

Place on the middle shelf for 40 mins, insert a metal skewer into the middle of the cake and when you pull it out and it comes out clean, the cake is done.
