My mix, not Jello Brand, says 1 serving of 1/2c when prepared w/ 2% milk contains 8g carbs. It only gives the prepared nutritional info on my package, not the mix info. I'm looking at it again now & it says "mix prepared w/ 2%" & is followed by the info. So thought it would be around 4g w/ heavy cream vs. milk. Maybe I'm wrong, if so sorry.
God Bless,
