Karithopita is a classic Greek walnut cake baked in a sheet pan and finished with a fragrant honey-cinnamon syrup poured over the cake while it’s hot. Cut into diamonds for a beautiful make-ahead dessert that’s perfect for holidays and gatherings.
For best texture, let the cake rest a couple of hours after adding the syrup so it soaks in evenly before slicing.
