In a 10 inch cast iron skillet, melt the butter and remove from heat.You can use a cake pan if you prefer. Use a pastry brush to coat the sides of the skillet with some of the butter.
Add the brown sugar to the butter in the skillet and combine well. Then spread it evenly over the bottom of the skillet.
Evenly distribute the drained pineapple over the brown sugar mixture.
If you use rings, arrange them to cover the brown sugar in any formation you wish.
If you’re using cherries, put as many as you want on the crushed pineapple and press gently.
If you’re using rings, place a cherry inside each ring and in between them as you desire.
In a small bowl, combine the flour, salt, and baking powder.
In a medium to large mixing bowl, cream the butter and sugar until light and fluffy. This usually takes 4-5 minutes
Add the eggs to the creamed sugar mixture one at a time incorporating well in between.

Bake at 350F for 30-35 minutes or until a knife or toothpick inserted halfway from the center comes out clean.
