This tastes so much like a chocolate milkshake right after making it. If you allow it to melt more it then tastes similar to chocolate milk.
3/4 cup chocolate syrup
1 12-oz. can fat-free evaporated milk
3/4 teaspoon vanilla extract
4-5 cups ice cubes
Combine all ingredients in a blender until smooth.
Pour into glasses and garnish as desired.
