I have used chocolate flavor cookies here, you can use any flavor of your choice.
Take a cookie and layer the inner surface with 2 spoonful of icecream.
Cover it with another cookie and press it slightly.
See to it that the icecream is filled from all sides.
Repeat this with the remaining cookies.
Keep the sandwhiches in freezer and quick freeze for 10 mins.
Top the icecream layer with edible sprinkles from outside before serving.
