Looking at my ingredient bags, cans, and fitday this is what I came up with.

Just for the carrot cake alone.
It gave me 12 servings in a 8x11.5 cake dish

butter- no carbs
splenda- not sure so this is not added in
1tsp. cinn. 2
1tsp. nutmeg 1
4 eggs raw-2
1 1/2 grated carrots 17
2/3 c. walnuts 11
1 cup soy flour- 32 - fiber= 16 carbs
protein powder 4 carbs

Total= 53 divided by 12 servings = 4.42 carbs. This is taking out the fiber from the soy flour and not adding the carbs from the splenda. I have no idea what that would be since on the box is says less than on carb per tsp.
If someone knows how many carbs are actually in 1 cup of splenda I would love to know!
( I have another recipe using 1 1/2 cups splenda and a whole bunch of other junk like cornstarch, and milk, and that carb count is only 2g. so it can't add much!
Later,
