Preheat oven to 350°F. Spray an extra large bundt pan (12-16 cup) with Pam Spray with flour. Line 6 cupcake liners in muffin pan.
In a small bowl, combine the flour, baking powder and salt.
In a large bowl, on the medium speed of an electric mixer, cream the butter until smooth. Add the sugar gradually and beat until fluffy, about 3 minutes. Add the eggs, 1 at a time, beating well after each addition. Add in the Nutella and mix. Add half the flour mixture and half the milk and mix. Add in remaining flour mixture and milk and mix until batter is smooth. Fill 6 cupcake liners about 2/3 full of batter. Pour remaining batter into bundt pan.
Bake for approximately 55 minutes until a toothpick inserted comes out clean for the bundt cake. Bake about 18-22 minutes for the cupcakes.
When the cake is cooled, you can melt some Nutella in the microwave to use as frosting.
