Avocado Smoothie

- 1 ripe avocado
- 1 cup 1/2 and 1/2, or 1/2 cup whipping cream plus 1/2 cup water (I suppose something like carb-countdown milk would work here, too, but I can't find it in any stores in SF)
- 1 cup ice cubes
- 2 tbs Splenda or 3 drops EZSweets
- 1/2 tsp vanilla extract

Blend until smooth and enjoy!
