In a cold bowl, whip the heavy cream until soft peaks form. Set it aside in the refrigerator until you're ready to serve.
If you're using an espresso machine, place a cardamom pod in the filter. Pack with the espresso, compact and brew. Alternatively, if you're using the instant espresso powder, bring 1/2 cup of water to a boil in a saucepan with the cardamom pods. Then whisk in the espresso, strain, and discard the solids.
To assemble: Place a generous scoop or two of ice cream in the bottom of 4 small glasses. Pour a shot of espresso into each glass, and top with a dollop of cream. Crumble the cookies over the top and sprinkle with grated dark chocolate. Serve immediately.
