Susan - I got this recipe off Dotties Weight Loss zone, not core, but maybe you can adapt it.
Makes 1 serving
1/2 cup low-fat (1%) milk
1/2 cup sugar-free vanilla nonfat frozen yogurt
1/4 cup brewed espresso, cooled to room temperature
3 ice cubes
1/2 tsp superfine sugar
1/4 tsp cinnamon
In a blender, combine all ingredients; puree until smooth. Pour into a tall,
chilled glass; sprinkle with additional cinnamon, if you like.
