Here is a simple egg custard that I make all the time.

5 large eggs (sometimes I use more, sometimes less, up to my chickens)
3 c Carb Countdown milk (or you can replace half this with heavy cream)
1/2 c splenda or 6 packets (or 1 tsp stevia powder or 5 packets)
3 tsp vanilla extract
1/2 tsp salt

Editing this now, I forgot to mention that you should grease the custard pan with butter or coconut oil.

Preheat oven to 350

Combine all and mix well with whisk. Pour into pan. Sprinkle with nutmeg if you like.

Place this pan in another bigger pan, I use a 13x9 inch glass baking dish. Pour boiling hot water in the bigger pan so that it comes up 1/2 to 3/4 the outside height of the pan containing the custard. (The secret to a good custard is baking it with water surrounding the pan it is in so that it bakes evenly.)

Bake for 40 to 60 minutes or until a butter knife inserted in center comes out clean.

Perfect every time.

Entire recipe has 12.8 carbs, therefore, 1/8 serving would have 1.6 carbs.
