*Lebni is strained keifer so its basically yogurt but it has the exact consistency of cream cheese and just about the same flavor; lebni has a bit of a lighter flavor with less bite. That makes it perfect for recipes like this. Bonus: its full of probiotics.
**Using Stevia as a Substitute:
1. Take 2 packets of stevia with 1 cup of arrowroot or potato starch and process them in a food processor.
2. Alternatively, you can process 4 packets of stevia with 1 cup of arrowroot or potato starch and 1 cup of whey protein powder.
3. Finally, you can process 4 packets of stevia with 1 cup of arrowroot or potato starch and 1 cup of powdered milk.
Ask someone at your market where to find the starches. Sometimes they're in baking, sometimes they're in health food... save yourself half an hour and ask.
I doctored this a bit and it was lovely! I replaced the cream cheese with lebni* which is available at any middle eastern market, (google your city name and "middle eastern market"). I used homemade stevia powdered sugar** and Safeway's O Organics fat free Vanilla because it tastes like crème fraîche.. I highly encourage using cubes of angel cake instead of lady fingers as the recipe suggests. It got really quiet at the table after I served it. :-D
