Preheat oven to 350°. Grease a 9-inch loaf pan with butter
In a large metal bowl, combine the flour, cinnamon, baking powder, baking soda, ginger, and salt; set aside
Use a stand mixer to cream butter, vanilla, and sugar until light and fluffy, about 5-7 minutes
Beat in eggs, one by one, and then add the pumpkin. Gradually add the flour mixture into the pumpkin mixture until blended
Transfer ½ a cup of the batter into the prepared pan. Drizzle 1 tablespoon of Nutella over the batter. Repeat layers; swirl the Nutella into the batter with a knife
Bake for about 45 minutes or until a toothpick inserted in center comes out clean
Cool in the pan for 10 minutes before removing to a wire rack. Cool completely
Serve and enjoy!
