Preheat oven to 350 F. Thoroughly butter a large loaf pan and then dust with flour {you can use 3 small loaf pans instead}, knocking all sides and dumping out loose flour.

In a medium mixing bowl, combine first 5 ingredients and set aside. In a separate bowl or stand mixer, combine the next 5 ingredients up to the nuts. Add wet and dry ingredients and stir just until combined. Fold in nuts.

Spread batter evenly in prepared pan. Drizzle Nutella on top of the batter, and then use a knife to swirl Nutella into the batter. Bake until a toothpick inserted into the center comes out clean, about 50-55 minutes. Let cool for a few minutes and then remove from pan to cool completely on wire racks. Enjoy.
