A little crescent moon of tender pastry, swirled with chocolate and hazelnuts – this is my favourite holiday cookie. Rugelach are Jewish in origin, and can be filled with pretty much anything, from jam, nuts and cinnamon sugar, to chocolate and poppy seeds. Because I am constantly looking for more ways to bring chocolate into my life, I fill mine with chocolate, hazelnuts and a slick of chocolate–hazelnut spread. The real genius here is the cream cheese dough, which is indestructible and so easy to work with. The richness and tenderness of the pastry is what makes these cookies.
