Creating Chocolate Nutella Rolls can be fun and straightforward if you follow these steps closely:

1. Prepare the Dough: In a large mixing bowl, combine the warm milk, sugar, and yeast. Let it sit for about 5-10 minutes until frothy.
2. Mix Ingredients: Add melted butter, eggs, and salt. Gradually incorporate the flour, mixing until a soft dough begins to form.
3. Knead the Dough: Transfer the dough to a floured surface and knead for about 5-7 minutes until smooth and elastic.
4. First Rise: Place the kneaded dough into a greased bowl, cover it with a kitchen towel, and let it rise in a warm place until doubled in size (about 1 to 1.5 hours).
5. Fill the Dough: Once risen, punch down the dough, and roll it out into a rectangle. Spread Nutella evenly across the surface and sprinkle with chocolate chips if desired.
6. Roll and Cut: Starting from one short end, tightly roll the dough into a log. Slice the log into even rolls, about 1 to 2 inches thick.
7. Second Rise: Arrange the rolls in a greased baking dish. Cover and let rise again for about 30 minutes until puffed up.

8. Bake: Preheat your oven to 350°F (175°C) and bake the rolls for about 25-30 minutes, until golden brown.
9. Cool and Serve: Remove from the oven and let them cool for about 10-15 minutes. Optionally, dust with powdered sugar before serving.

By following these straightforward steps, you can create an incredible batch of Chocolate Nutella Rolls that are sure to impress any chocolate lover.
