Make a simple syrup by dissolving a 1/2 cup of sugar in the water in a small saucepan. Bring to a boil and remove from heat to cool.
Combine the strawberries, ice cream, milk and vodka in a blender, and blend on high speed until smooth.
Chop the shortcake into breadcrumb-sized pieces. Toast in an even layer on a parchment lined baking sheet in a toaster oven or in a standard oven at 200º F for 3-4 minutes until golden and slightly dry.
Add a shortcake rim to your glasses by dipping the glasses into a 1/4 inch of simple syrup and immediately rolling the rims in the shortcake crumbles.
Fill the glasses with the strawberry milkshake and top with a generous dollop of whipped cream. Garnish with a strawberry slice.
