Babka is a sweet, twisted bread that is popular during Purim. With a food processor, you can easily make the dough for a chocolate babka. In the food processor, combine flour, sugar, yeast, salt, eggs, and butter until the dough forms. Let it rise until doubled in size. Meanwhile, prepare the chocolate filling by blending together melted chocolate, sugar, and cinnamon. Roll out the dough, spread the chocolate filling, and roll it up tightly. Cut the roll in half lengthwise and twist the two halves together. Bake until golden brown and enjoy this decadent chocolate babka!
