When making Chocolate Babka, a few steps will go a long way. First, prepare the dough. Yeast is a basic baking ingredient. Then, add eggs, sugar, butter, and chocolate. Stir until smooth. Refrigerate for at least 20 minutes, then divide the dough into two equal parts. Once chilled, cut into triangles with a sharp knife. Once cooled, place the pieces on a wire rack to cool.
