To Make the Frozen Yogurt: While tortillas are cooling make the frozen yogurt by placing everything in the blender, and blending until creamy.
To Make the Waffle Bowls: Preheat the oven to 375F degrees. In small bowl mix together sweetener and cinnamon. Microwave tortillas for 30 seconds until warm. Place tortillas draped over bowls on the baking sheet, lightly pressing them down, forming them around the bowls. Spray the tortillas lightly with cooking spray, and sprinkle with cinnamon mixture. Bake in hot oven for 10-15 minutes, or until the tortillas are lightly brown, and/or starting to get crispy. (Will crisp up as they cool). Remove from oven and let cool completely.
To Serve: Divide the frozen yogurt mixture among the cooled tortillas and top with fresh berries if desired!
(Note: If you are not eating the frozen yogurt right away, place in a covered container in your freezer. Don't leave it in the freezer for more than a few hours, or it will start to get icy.)
