Preheat the oven to 350 degrees. Prep a sheet pan that is approximately 11×17 inches in size. Line with a sheet of parchment, spray with some non-stick spray and sprinkle with a little bit of flour.
In the bowl of a stand mixer, combine the sugar, softened butter, and cream until smooth. Add in the egg whites, oil, milk, baking powder, salt and cake flavoring. Mix well.
