Okay, just made these (2 batches in fact) and they were terrific!
I made mine with Keto Orange Creme shake mix (only kind I had) and boy are they good. Can't wait to try different flavors.
My only concern is:
I put the recipe into Mastercook, the exact ingredients you had (except using orange flavor shake instead of vanilla). Mastercook tells me there are 24 gr carbs minus 7 gr fiber still leaves 17 gr. carbs!? Am I missing something??
How did you come up with 5.5 gr. carbs??
