Greek Walnut-filled Chocolates (Kariokes)

My Kariokes will make you sing! Nope, I’m not going to wail at you at the top of my lungs (no one deserves that) - I’m talking about Greek Kariokes, a walnut-filled chocolate treat. This recipe is the perfect easy-yet-stylish dessert for a dinner party, and looks so special - even though you can get all the work done in advance!
