Here's a link to a recipe from Gourmet that definitely has low-carb possibilities: http://www.epicurious.com/run/recipe/view?id=106125

It's a baked custard made with cream and milk that has been flavoured with tea, cinammon stick, cardamom, cloves, and fresh ginger. To make it low carb you would just have to substitute cream for the milk and sweetener for the sugar. I haven't tried it. I can't get whipping cream that doesn't contain dextrose, and things are going so well that I don't want to risk it. However, our 18% coffee cream is dextrose-free, and I might work out the carb count based on that.

Reviewers said that it had a pumpkin pie taste that some disliked, but then spiced chai has a pumpkin pie taste.
