I haven't seen this mentioned in a very long time, but there is a brand of sugar-free chocolate powder called Gosh That's Good, and it is my saving grace. I drink plain coffee all week, and then on the weekends I NEED a mocha - it's just been a habit for over a decade!
Anyway, so I go to a drive-thru coffee place and they had this "Gosh That's Good" SF Chocolate option listed, and I went for it. Seriously, this stuff tastes AWESOME.
I'm diabetic and it causes absolutely no blood glucose spike. It also doesn't affect ketosis!
NO Traces of Sugar
NO Hydrogenated Oils
NO Corn Syrup
Now - I won't lie, it's not cheap, but you only use 1T, and there's 170 servings per 2 pound bag.
OH, and they also have a White Velvet Chocolate, too
Gosh That's Good
Well, I hope you like it as much as I do
Maybe you can get your local coffee shop to carry it! I had mine make iced mochas all summer, but now I've switched back to hot ones
(My coffee shop charges an extra 75 cents for adding it in.)
