Chocolate babka is made from a rich, tender dough that is similar to brioche or challah bread. The dough is swirled with rich dark chocolate, resulting in a delicious treat for breakfast or brunch. In this online cooking class, we will show you how to bake this New York City favorite at home. The bread's richness comes from butter and egg yolks. The filling is made from a combination of bittersweet chocolate and cocoa powder, which creates full chocolate flavor and a fudgy texture. Our instructor will walk you through how to shape and swirl the bread so that it looks beautiful when you slice into it.
