Preheat the oven to 350°F (180°C) and grease a round cake pan.
Melt 1/2 cup of unsalted butter in a saucepan over low heat, then add 3/4 cup of brown sugar and stir until dissolved.
Pour the butter and sugar mixture into the cake pan, spreading it evenly.
Arrange the pineapple slices on top of the sugar mixture, placing a cherry in the center of each slice if desired.
Set aside while you prepare the cake batter.
In a mixing bowl, cream together 1 cup of melted butter and 1 cup of granulated sugar until light and fluffy.
Add the eggs one at a time, beating well after each addition, then stir in 1 teaspoon of vanilla extract.
In a separate bowl, sift together 1 1/2 cups of all-purpose flour, 1 teaspoon of baking powder, and 1/2 teaspoon of salt.
Gradually add the dry ingredients to the wet mixture, alternating with 1/2 cup of milk, until well combined.
Pour the batter over the pineapple slices in the cake pan, spreading it evenly.
Bake for 40-45 minutes or until a toothpick inserted into the center comes out clean.
Allow the cake to cool in the pan for 10 minutes, then invert it onto a serving plate.Elvis Presley CakeCreamy Treats
