If you have a regular blender, slice strawberries. If you have a nice heavy-duty blender, just halve the berries. Place in a bowl, sprinkle with vanilla extract and coat with sugar. Let sit for at least 20 minutes (can be refrigerated for later).
Place the following ingredients in the blender in this order: Milk, Ice, Ice Cream, then Strawberries. Blend well.
This recipe made four 10-oz milkshakes.
