Oh wow! I just read this recipe half hour ago and just HAD to try it! I used
1 medium egg,
2 oz cream cheese,
3 tsp splenda,
and a dash each of lemon and vanilla essence.
Nuked in microwave for about 2 mins, stirring every so often.

I thought it was gorgeous! And enough for 2 portions definately! Cant wait to try it with other flavours now!
