Start with two large cookies of your choice.
Soften the ice cream slightly at room temperature for about 5 minutes.
Place one cookie on a flat surface.
Scoop the ice cream onto the cookie, about 1 cup or more as desired.
Spread the ice cream evenly across the cookie.
Top with the second cookie, pressing down gently.
Roll the edges in chocolate chips or sprinkles if desired.
Wrap the sandwiches in plastic wrap.
Freeze for at least 1 hour to firm up.
Unwrap and serve chilled for the best experience.
