This shake makes two servings.
4 scoops vanilla ice cream
4 cream filled chocolate or chocolate & vanilla cookie sandwiches
1 c milk
First break the cookies in half then in half again. Drop them in the bottom of the blender and hit the pulse until they are no longer in big chunks (yes pulse them dry). Then add in your ice cream and milk, you may want to add the cup of milk gradually, some ice creams won't need as much, and depending on how you like the consistency of your milkshake.
I do recommend getting the ice cream out about 5 minutes prior to making the shakes, it blends easier.
