Let the ice cream soften just a bit.

Spread the nuts out on a large plate.

Scoop ice cream on a cookie bottom. You want enough so that it just sticks out around the edges when you press the other cookie down on top of it. If you have to, run a knife along the edges to smooth them a little.

Roll the edges in the nuts, pressing down slightly.

Wrap in small pieces of foil or plastic wrap and return to the freezer for 10-15 minutes to harden.
