Place pitted dates in the food processor and process until broken down, next add the Tahini. Once that is well blended add the Coconut, process. Finish by adding the Lime juice. Once it is all well combined remove dough-like batter to a bowl, and using a spoon mix in Cocoa Nibs (amount you desire).
Roll the dough into a large ball and place between 2 sheets of parchment paper, using a rolling pin - roll flat until about 1/4" thick.
Place in freezer for a few hours, then carefully use a knife or cookie cutter to cut them into desired shapes.
Store in freezer.
Notes
Feel free to experiment, instead of cocoa nibs - use vegan chocolate, add in some dried fruit - let your imagination run wild!
