Spread 1 heaping tablespoon of Nutella on the bottom side of each cookie. Transfer the cookies to a baking sheet and freeze for 15 to 20 minutes or until the chocolate has firmed up completely.

Using a medium size ice cream scooper, place one scoop of ice cream on half of the cookies. Place the remaining cookies on top of the ice cream to form a sandwich. Transfer the sandwiches back to the freezer to firm up.

Wrap the ice cream sandwiches individually and store in a resealable container or bag in the freezer for up to 2 months.
