3. Pour Mixture: Pour the butter and brown sugar mixture into the prepared cake pan, spreading it evenly.
4. Arrange Pineapple: Arrange the pineapple slices on top of the brown sugar mixture. Place a cherry in the center of each pineapple slice. Sprinkle optional chopped walnuts around.
5. Mix Dry Ingredients: In a medium bowl, combine flour, baking powder, baking soda, and salt.
6. Cream Butter and Sugar: In a large bowl, cream the softened butter and granulated sugar until light and fluffy.
7. Add Eggs and Vanilla: Beat in the eggs, one at a time, followed by vanilla extract.
8. Combine Mixtures: Gradually add the dry ingredients to the butter mixture, alternating with the reserved pineapple juice. Mix until just combined.
9. Pour Batter: Pour the batter over the arranged pineapple and cherries in the cake pan, spreading it evenly.
10. Bake: Place the pan in the preheated oven and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
11. Cool: Once baked, remove the pan from the oven and let it cool for 15 minutes. Then, carefully flip the cake onto a serving plate.
