Place the cookies on a flat surface with their bottoms facing up.

Scoop a generous amount of ice cream onto the flat side of one cookie.

Gently press another cookie on top to form a sandwich.

Smooth the edges of the ice cream with a knife or spoon.

Roll the edges of the ice cream in chocolate chips, sprinkles, or crushed nuts if desired.

Place the assembled sandwiches on a tray lined with parchment paper and freeze for at least 1 hour to set.

Serve directly from the freezer for a cool and satisfying treat.
