Take a half cup of milk or little lesser than half ..
Take around 2 medium scoops of vanilla ice cream x)
I usually take 2 Oreos ... You can take more or less .. Depends if you want your milkshake to be thick or thin
Pour the milk, vanilla ice cream and Oreo into the blender x)
Start the blender and when you think your Oreos are mixed well .. Stop the blender .. And there you go with your easy homemade milkshake x)
