This creamy cheesecake takes less than an hour to mix, assemble, and bake--but you'll need to wait at least four hours for it to chill properly before serving. The taste and texture only improves over time, so make it a day ahead, if possible. Yogurt replaces some of the cream cheese for a lighter, tangier result; espresso lends deep flavor to the filling. This is a no-crust cheesecake, meaning it's gluten free. Chocolate syrup is drizzled over the top, or you could melt dark chocolate and use that instead.
