This is not seriously low-carb, but it sure is lower carb than most coffee shop drinks. Some do have sugar-free syrups, but if you’re also avoiding artificial sweeteners, those won’t do. This will! Feel free to make this a cup at a time using 6 ounces of half and half, 6 ounces of coffee, about 18‑20 drops of chocolate stevia extract, and a teaspoon of cocoa powder. You’ll just have leftover whipped cream. Which means you’ll need to keep it in the fridge, ready to make another cup. Shucky‑darn.
If you like, make this with English Toffee flavored liquid stevia instead, leaving out the cocoa powder.
