This is the one we've been using:

1/4 cup Splenda (6 carbs)
1/4 cup Sugar Twin (2.16 carbs)
3/4 cup butter, softened
6 eggs (3.6 carbs)
2 tsp. vanilla (ours has 0 carbs)
1.5 cups soy powder (12 carbs)
1.5 cups flaxseed meal
2 tsp. baking powder (2.4 carbs)
1/4 tsp salt
1 cup cream (6.4 carbs)

Preheat oven to 350 degrees F. Heavily grease a loaf pan (we use olive oil). Beat moist ingredients, including butter, for 5 minutes. Add dry ingredients and beat on low speed till well-blended. Pour into pan. Bake for 50-60 minutes, using toothpick test to determine when done. Cool for at least 20 minutes before attempting to remove from pan. (32.56 carbs/loaf) We usually get at least ten slices, sometimes more, from each loaf which works out to about 3 carbs/slice or less.

This began as a pound cake recipe but works better as a nutty-flavored bread.
