Place the coconut, dates, and walnuts in a food processor. Process the ingredients until they’re finely chopped.

The mixture will be crumbly if you leave it like this, so add about a tablespoon of water a little bit at a time. Process after each addition of water. Once the mixture starts to clump into a ball as it’s spinning around in the food processor, it’s done. If you add too much water, you can put in a little more coconut and/or walnuts to dry it out.

Transfer the mixture to a loaf pan lined with wax paper. Press down to make an even layer, then cover the pan and refrigerate for at least an hour.
