Preheat oven to 350°F. Grease and flour a standard sized loaf pan.
In the bowl of a stand mixer with the paddle attachment, beat sugar and butter on high speed until fluffy and fully mixed. You can't over mix it at this point in the recipe. Beat in eggs 1 at a time on low speed. Add vanilla.
In separate bowl, combine flour, baking powder and salt. Gradually add to sugar mixture, scraping down sides to ensure everything is fully mixed. Pour batter into prepared pan.
Bake 1 hour or until toothpick inserted in center comes out clean. Set loaf pan on a cooling rack and as soon as the pan is cool enough to handle, remove cake from pan and turn out on rack to cool completely.
Top with Sweetened Whipped Cream and fresh fruit, if desired.
