Preheat the Oven: Start by preheating your oven to 350°F (175°C). This ensures that your cake will bake evenly.
Prepare the Pan: In a round cake pan, melt the 1/4 cup of butter over low heat. Once melted, sprinkle the brown sugar evenly over the butter.
Arrange the Pineapple: Next, arrange the pineapple slices on top of the brown sugar mixture, allowing them to overlap slightly, and sprinkle shredded coconut over the pineapple for that tropical touch.
Mix Dry Ingredients: In a medium bowl, combine the all-purpose flour, baking powder, and salt. Set aside.
Mix Wet Ingredients: In a separate large bowl, whisk together the granulated sugar, milk, eggs, and vanilla extract until well combined.
Combine Ingredients: Gradually add the dry ingredients to the wet mixture, stirring gently until everything is just combined.
Pour the Batter: Carefully pour the batter over the arranged pineapple and coconut in the pan, making sure it spreads evenly.
Bake the Cake: Place the cake in the preheated oven and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
Cool and Serve: Once baked, allow the cake to cool for a few minutes before carefully inverting it onto a serving plate.
Enjoy Your Creation: Slice and serve warm or at room temperature—enjoy every delightful bite of your homemade cake!
