Preheat oven to 350˚F
Melt ¼ cup butter in 10 inch cast iron skillet. Add ½ cup brown sugar, mix and spread evenly.
Drain sliced pineapple well. Pat dry a bit. Set aside.
In a medium bowl whisk together flour, baking powder and salt. Set aside.
In a large bowl, cream butter and slowly add sugar until white and fluffy.
Add eggs one at a time and beat in between each addition.
Alternate adding dry ingredients and cream, beating well after each. Add vanilla.
Add pineapple slices to skillet, add maraschino cherries and sprinkle with chopped pecans.
Carefully pour the cake batter over pineapple.
Bake 25-30 minutes. Check early for doneness. If a toothpick inserted in the center comes out clean, it is done.
