Use frozen berries to give these ice cream shakes an extra chill.
1quart vanilla ice cream
6ounces unsweetened frozen berries (such as strawberries, blackberries, and blueberries)
2cups whole milk
In a blender, combine half of the ice cream, berries, and milk. Purée until smooth, stopping occasionally to stir with a spoon. Pour into glasses. Repeat with the remaining ingredients.
