Add the vanilla ice cream, whole milk, and vanilla extract to a blender. Make sure to use good quality ice cream, as it will make a big difference in the flavor and texture of your milkshake.
Blend the mixture until it is smooth and creamy. You can adjust the amount of milk to your liking, depending on how thick or thin you prefer your milkshake.
Pour the milkshake into a tall glass. If you want, you can top it with whipped cream for an extra special touch.
Serve and enjoy your delicious vanilla milkshake!
