Preheat oven to 350˚F. Cream the butter until light and fluffy, about 5 minutes.  Sift the cake flour, salt, baking powder and baking soda together.  In a food processor, pulse the macadamia nuts and sugar until roughly chopped.   Place the butter in a mixer, fitted with the paddle attachment.  Mix until smooth, and then add the sugar and nut mixture.  Add the eggs one at a time, scraping the sides of the bowl in-between additions.  Add the vanilla extract; scrape the sides of the bowl.  Then, alternate the dry ingredients with the sour cream, starting with the dry ingredients.  Mix until well combined, being careful not to over mix.  

Mix the butter topping, by mixing the melted butter with the brown sugar.  Prepare the cake pan by spraying it with pan spray.  Lay thin layer of the butter topping down inside the pan.  Arrange the sliced pineapple in the bottom of the cake pan.  Pour the cake batter over the pineapples, trying not to disturb them.  Bake for 15 minutes then rotate the cake.  Bake for another 10- 15 minutes or until the top is golden brown and a toothpick comes out clean once inserted.  Let cool completely inside the pan.  Use a knife to loosen the cake from the pan and place a dinner plate, larger than the cake on top.  Invert the cake and remove the pan; cool. Serve topped with Butterscotch Sauce and (optional) with a side of “Soybet” and Pineapple Curd.
