Process all ingredients in a food processor until the mixture combines and becomes more or less uniform and begins to lump together.
Transfer the mixture into a 5" springform pan (or a small parchment-lined tupperware container of a similar size). Press the mixture down to pack it in with the back of a spoon as evenly as possible. Cover with another piece of parchment paper and press down with a flat-bottomed object (like the bottom of a measuring cup, etc.) to pack it down even more.
Freeze for 4-5 hours or overnight. Remove from pan, cut into pieces, dust with additional carob (use a small sieve for even dusting), and enjoy! Keep leftovers frozen, or refrigerated if you prefer a softer consistency.
