Put the whole milk and flavoring (vanilla extract, chocolate sauce, chopped Oreos, or sliced strawberries) into the blender. When making a chocolate milkshake, mix the milk and chocolate sauce until combined. Then add the vanilla ice cream.
Blend until smooth.
Pour into two chilled glasses.
Top with whipped cream, a maraschino cherry, and garnishes of your choice.
